Advanced Soldering Materials for PCB Assembly

Table of Contents

With the advent of increasingly intricate and compact electronic devices, the demand for sophisticated soldering materials for Printed Circuit Board Assembly (PCBA) has skyrocketed. The extensive miniaturization of electronic devices necessitates soldering materials that can withstand the challenges of PCB assembly while ensuring robust performance, longevity, and overall device integrity. This article delves into the fascinating realm of advanced soldering materials and their impact on the evolving landscape of PCBA.

Traditionally, soldering has relied on alloys like tin-lead. The industry has switched towards lead-free alternatives due to the necessity to comply with environmental requirements, particularly the Restriction of Hazardous Substances (RoHS) directive. The most widely accepted alternative today is the tin-silver-copper (SAC) alloy. Yet, as device dimensions shrink and complexity escalates, the search for more efficient materials is relentless.

Advanced Soldering Materials

Innovations in the sphere of soldering materials have given birth to a number of promising substances designed to answer the emerging challenges of PCBA. Two particularly intriguing advancements are nano-solders and composite solders.

Nano-solders

Nano-solders are a new breed of soldering materials that contain nanoparticles. These nanoparticles dramatically modify the microstructural characteristics of the solder joint, resulting in improved mechanical properties, better wetting characteristics, and lower melting temperatures.

A comprehensive study of nano-solders involves observing the interactions at a microscopic level. This knowledge is vital for understanding their behavior during the soldering process and subsequently their performance in PCB assemblies. For instance, the addition of ceramic nanoparticles to a solder matrix can improve its resistance to electromigration – a critical problem in high-density PCBs.

Composite Solders

Composite solders are another revolutionary development in the PCBA industry. They consist of traditional solder alloys, such as SAC, combined with other materials (usually in particulate form) to enhance certain properties. For example, the addition of nickel particles to a SAC solder can significantly improve the solder’s shear strength.

Composite solders bring forth the possibility of tailoring solder properties to match specific PCBA requirements. This adaptability makes them a promising option for high-performance applications, including aerospace and medical devices.

High-Reliability Alloys

For applications where reliability under extreme conditions is a must, such as aerospace, automotive, or military electronics, high-reliability alloys have been developed. These include the tin-antimony (SnSb) and tin-bismuth-silver (SnBiAg) alloys. The latter is a low melting point alloy, particularly suitable for delicate, heat-sensitive components.

Low-Temperature Alloys

The demand for low-temperature alloys, which can solder at decreased temperatures to protect heat-sensitive components, has grown in tandem with the miniaturization of electronic equipment. Tin-bismuth (SnBi) alloys, for instance, have gained popularity due to their lower melting point compared to traditional SAC alloys.

Indium Alloys

Indium alloys are another category of advanced soldering materials that offer unique properties. Indium-based solders have excellent thermal and electrical conductivity and are particularly useful when the solder joint needs to be a good conductor. Moreover, they can resist thermal fatigue better than many other solders, making them a top choice for high-temperature applications.

Micro-alloyed Solders

Micro-alloyed solders are those that incorporate a small amount of a distinct element to the base alloy to improve its properties. This category includes the likes of doped SAC alloys, where trace elements like manganese or nickel are added to the SAC base. These elements improve the drop-shock resistance and can also mitigate the occurrence of tin whiskers.

Bi-Ag Alloys

One of the rising stars of the advanced soldering materials sector is the bismuth-silver (BiAg) alloy system. This system is receiving much attention as an alternative to high-lead soldering alloys, which are exempt from RoHS but still pose an environmental hazard. BiAg alloys exhibit high thermal and electrical conductivity, good wettability, and high shear strength. They offer a greener, yet high-performing option for soldering applications demanding superior mechanical and thermal reliability.

PCBA

Factors Impacting the Choice of Soldering Materials

A significant element to consider is the solder’s melting temperature. The working environment’s thermal conditions should align with the solder’s melting point to avoid premature failure. Another vital aspect is the material’s mechanical properties. A PCB in a high-vibration environment, for instance, needs a solder with high shear strength to ensure the joints remain secure.

Towards a Sustainable Future

Despite the dazzling prospects offered by these advanced materials, there remains an elephant in the room – sustainability. The electronics industry, including PCBA, must grapple with the environmental implications of their processes and products. Thus, finding sustainable soldering materials is as crucial as improving performance metrics.

For instance, the incorporation of recycled materials into solders is an emerging trend. Some companies are exploring the potential of using recycled tin and other metals in solder alloys to reduce the environmental impact.

The Future of PCBA with Advanced Soldering Materials

The future of PCB Assembly, with advanced soldering materials, paints a vivid picture. The integration of nano and composite solders promises not only better device performance but also greater customization, fitting the specific needs of various applications.

Further, the ongoing research and development in this field open doors to a world of potential. PCBA could see breakthroughs in reliability, miniaturization, and sustainability, all thanks to these cutting-edge soldering materials.

PCBA has come a long way from its humble beginnings, with soldering technology integral to this journey. As we stand on the precipice of a new era, advanced soldering materials hold the promise of propelling PCBA into an exciting future filled with endless possibilities.

While the challenges are significant, the potential rewards are greater. As we continue to explore these materials, we can expect to see a profound impact on the PCBA industry. Here’s to the future of PCBA and the soldering materials that will lead us there!

9 Must Know PCB Assembly (PCBA) Equipment

As the lifeblood of numerous modern devices, printed circuit board assembly (PCBA) has revolutionized technology as we know it. PCBs, or printed circuit boards, are complex electrical pathways that breathe life into your phones, computers, and a whole gamut of electronics. However, the quality of such complex gadgets depends on the machinery employed in their construction. Let’s uncover nine key types of PCBA equipment vital to the process.

FX PCB can provide the ALN(Aluminum oxide) and AIO203(Aluminum Nitride) Ceramic PCB, we can make ENEPIG, ENIG, Immerison silver surface,you can check the material datesheet and our capability from the below tables.

Ceramic PCB is actually made of electronic ceramic materials and can be made into various shapes.

The ceramic circuit board has the following characteristics: high-temperature resistance, high electrical insulation, low dielectric constant, low dielectric loss, high thermal conductivity, good chemical stability, and the thermal expansion is almost can be coefficients of components.

1. Screen Printer

A good journey begins at the base. The initial step in PCB assembly is applying solder paste to the board, and for that, we need a screen printer. With its metal stencil, a screen printer ensures the solder paste is applied uniformly and precisely where required. Without this, the components wouldn’t stick to the board or form good electrical connections. It’s an essential part of PCBA, without which your devices might end up being just a jumble of parts.

2. Pick and Place Machine

Next in line, we have the pick and place machine—a true marvel of precision and speed. This device automatically picks electronic components from a feeder and accurately places them on the solder paste on the PCB. Considering the intricate design and minute size of many components, this equipment requires exceptional precision and reliability. Just imagine; a standard PCBA can have hundreds or even thousands of components, each of them having their rightful place on the board.

3. Reflow Oven

Ever baked a batch of cookies? The reflow oven does something similar, just not as delicious. After the components are meticulously placed on the board, the entire assembly goes into the reflow oven. Here, the solder paste melts, or “reflows,” effectively bonding the components to the PCB. This intricate baking process is critical as it dictates the quality and durability of the final assembly.

4. Automatic Optical Inspection (AOI) Machine

In any production process, quality assurance is indispensable, and that’s where our fourth equipment, the AOI machine, comes in. After the soldering process, the AOI scans the PCB for any potential defects. These can range from incorrect component placement to insufficient soldering. 

5. Wave Soldering Machine

The wave soldering machine is a tried-and-tested veteran of PCBA. It’s primarily used for through-hole component soldering, a type of assembly where components are mounted by inserting leads into holes drilled into the PCB. The machine works by sending a “wave” of molten solder that washes over the bottom of the board, soldering the leads in the process. This method, although a bit old-school, is efficient and effective for certain types of PCBs.

6. Solder Paste Inspection (SPI) Machine

SPI machines evaluate the quality of the solder paste application after the screen printing phase. With the help of high-precision 3D sensors, they detect any discrepancies in the volume, area, and height of the solder paste deposits. This meticulous attention to detail allows for the early identification of defects before the components are placed, thereby preventing potential complications further down the line.

Given the tiny margins of error in PCB assembly, the role of the SPI machine cannot be overstated. It’s more than simply a piece of hardware; it plays a crucial role in preventing errors in the PCBA process and ensuring the highest possible quality of the end product.

PCBA

7. X-Ray Inspection Machine

Some defects are not visible to the naked eye, or even the AOI. Enter the X-Ray Inspection machine. This equipment enables a non-destructive method to view solder joints under the surface of the board. It’s like giving the PCB a CT scan to check the integrity of solder joints, especially for components like BGA (Ball Grid Array) that have hidden connections underneath.

8. Rework Stations

Rework stations are equipped with advanced tools and technology to perform precise desoldering and resoldering of components that need to be replaced or removed. Their precision is of paramount importance, as they need to extract components without damaging the PCB or surrounding elements.

Moreover, rework stations have a critical role in managing fine pitch components—those with leads too close together for conventional soldering tools. By efficiently handling these delicate components, rework stations ensure they do not become a bottleneck, thereby preserving the overall speed and efficiency of the assembly process.

9. PCB Router Machine

Once all the components have been successfully placed, soldered, inspected, and reworked if necessary, the assembly process enters its final stage. Now, it’s time to separate individual PCBs from the large panel they were assembled on.

Imagine the PCB Router machine as a skilled surgeon performing a delicate procedure. It meticulously cuts the panels, freeing the individual boards while ensuring clean edges and minimizing potential damage to the finished product. This is achieved through a process called ‘routing,’ where high-speed spindles precisely mill the panel along the pre-determined paths.

The router machine’s accuracy plays a crucial role in the final presentation of the product. A slip-up here could damage the meticulously assembled PCBs. Thankfully, these machines boast a high degree of precision, ensuring that the fruits of the entire PCBA process are preserved in their prime condition, ready for their role in powering our modern world.

Bottom Line

Remember, a good PCBA process is like a well-conducted orchestra. Each instrument, or rather equipment, plays its role at the right time, leading to a harmonious symphony of technology that powers our modern world.

So, you’ve been introduced to the remarkable world of PCB Assembly equipment, each playing its pivotal role in bringing our beloved electronic devices to life. It’s an intricate dance of precision and quality, with no room for error. Now, where can you find such exceptional quality PCBA?

Difference Between PCB And PCBA

The Key Difference Between PCB And PCBA: What You Need To Know

Modern-day smartphones are doing wonders with the developed camera, higher refreshing rate, and hardware improvement. Similarly, contemporary warfare has seen tremendous use of drone helicopters to spy on enemies.

All these have been made possible because of the advancement of PCB and PCBA. These two technologies have changed the communication, electronics, military, medical device, etc. industries dramatically.

Yet we found that many people consider the PCB and PCBA the same thing. Hence, we decided to discuss the difference between PCB and PCBA in a way so everyone can understand it.

PCB is a bare circuit board consisting of only the signal transmitting and heat dissipation substrate. The PCBA, on the contrary, consists of different electronics components including ICs, resistors, etc.

Ceramic PCB is actually made of electronic ceramic materials and can be made into various shapes.

What Are PCB and PCBA?

PCB, as we all know, stands for Printed Circuit Board. It is the fundamental of modern-day and highly complicated electronic devices. It is made for both electrical transmission and mechanical support to the other components.

The base is made of different metals, ceramics, or other elements and it works as the substrate. It dissipates the heat to reduce the temperature of the components mounted over it. This is the mechanical support of the PCB. And electronic transmission refers to the data transfer from one component to another through the base.

However, the PCB is a bare electric circuit board. It has only the substrate and conductive parts. The electronic device manufacturer will mount the electronic components over the bare PCB. This process is called the PCBA which stands out for the PCB Assembly.

The PCBA has a different layout and uses a soldering process to complete the entire component mounting and assembly process.

The Key Difference Between PCB And PCBA

Although you might not understand, PCBA and PCVB comes with subtle differences. If you are in the PCB and PCBA industry or electronic device manufacturing, understanding these distinctions between the two essential parts of your electronic device production is important.

The key differences are-

  1. PCB is made to dissipate the heat generated during electrical signal transmission. It has a heat-dissipating layer and an insulation layer on its top. However, it doesn’t contain any wiring or electric components. The PCBA is the next part of device manufacturing that follows PCB production. It has various components including ICs, registers, transistors, SMD capacitors, etc.
  2. The PCB is made of scratch using various metal or non-metal surfaces. On the contrary, the PCBA is built upon the PCB. This is a key distinction between the two parts of device production. Once the PCBA manufacturer gets the PCB ready at his hand, he can work over it to assemble the various components on it.
  3. The printed circuit board is of various types and it is determined, mostly, by the material used in its substrate. Thus, you have to look at the substrate material to find the actual type of the PCB. The list includes FR4, ceramic, or metal PCB. PCBA, however, doesn’t have such classification based on the materials.
  4. PCB can also have single or multiple layers of substrate. Thus, it is also classified as single, dual, or multi-layered PCB. There are also flexible and rigid PCBs. Nonetheless, PCBA doesn’t have such types of variety. Its classification comes from mainly the components mounted over it.
  5. PCB has one standard manufacturing process. However, PCBA follows multiple ways to mount the components on it. You may follow the automatic reflow soldering or wave soldering for PCBA manufacturing.
  6. PCBA manufacturing needs a definite layout to mount the components according to the design. It differs due to the requirements of device variations. Also, the layout is a software-based design. PCB follows a generic design for all devices.

A Hint on the PCBA Manufacturing Process:

Different manufacturers follow a standard PCBA manufacturing process. The main difference comes in the soldering process primarily. Also, there are distinctions in the component types also mounted over the PCB.

The twocomponent types are-

  1. SMD components: SMD component refers to the standard surface mount electronic devices and components. Manufacturers use SMT or surface mount technology to mount the SMD components on the PCB. You have to count the number of actual pins attached to the components to identify the SMD ones.
  2. Through-hole components: It is also referred to as thru-hole components mainly because of their design. It has multiple leads on the base and these leads will be mounted on the PCB surface. You need to create holes using a drill machine to mount these thru-hole components on the printed circuit boards.

Another part of PCBA manufacturing is the soldering technique. Usually, the PCB and the required components to build the PCBA passes through the pick and place machine to initiate the actual soldering process.

When the PCB passes through the pick and paste machine, it places the components on the bar circuit board. It follows a design layout provided by the PCBA manufacturer to arrange the components in the proper way. The bare circuit board however has soldering glue pasted on it before it enters the machine for attaching the electronic parts.

These days, manufacturers like FX PCB usean automatic soldering process to mount the components safely over the circuit board permanently. It is also known as the reflow soldering system. It is a fast and safe process of manufacturing a bulk amount of PCBA without any faults.

Previously, manufacturers opted for the wave soldering mechanism. However, it has become outdated now. It has many flaws which have forced the PCBA producers to leave it forever.

Conclusion

The main difference between PCB and PCBA lies in the manufacturing mechanism and steps. PCB follows a generic manufacturing system. On the contrary, PCBA design varies according to the requirements of the device manufacturer. The layout is done in software and a machine is used to arrange the components according to the layout.

FX PCB manufactures both PCB and PCBA and also serves you with the design layout so you can build your device on it at ease. Also, our pricing is competitive and we offer delivery in any amount you need for the project.

PCBA Manufacturing Process

PCBA Manufacturing Process

PCBA Manufacturing Process

The modern-day electronics world depends heavily on the Printed Circuit Boards (PCBs) as its backbone. The miraculous invention has paved the advancement of electronics of all sorts. A PCB is a medium to transfer the current through its copper pathway and it dissipates the heat to keep the tiny yet highlycomplex electronic equipment on it in perfect condition.

The PCBs are arranged with various electronic components such as ICs, transformers, transmitters, etc. Once the PCB is mounted with these components, it is called the PCBA. Hence, the PCBA manufacturing process follows solder paste, picking and placement of the component, soldering, and final inspection stages.

If you are to get the best PCBA and PCB for your digital devices, you have to know this PCB assembly process thoroughly. FX PCB with its years of experience understands this need and thus, we present you the detailed guideline on the printed circuit board assembly process.

Table of Contents

What Is The Difference Between PCB and PCBA?

During our long working time in the PCB industry, we have seen a majority of people considering the PCB and PCBA the same thing. Thus, before we move to the PCBA manufacturing steps, let’s clarify the confusion you have.

The PCB is a bare substrate with copper or other metal on it working as a base to dissipate the heat. Also, it transfers and transmits data electronically. When a PCB is built, it is a bare component.

During the PCBA manufacturing, this bare PCB will be used as a base to mount various electric components. The list includes transistors, resistors, ICs, transmitters, etc. Once you mount the electric components on the PCB, it is called the PCBA.

You have to use soldering to complete the PCB assembly.

Steps to Follow For the PCBA Manufacturing Process

Almost all PCB and PCBA manufacturers follow a standard process to manufacture the PCBA. FX PCB is no exception to it. Our process includes solder pasting on the PCB base, placing the electronic components in the right place, soldering them with the PCB, checking the accuracy, final inspection, and delivery to customers.

The entire process is monitored closely to ensure 100% accuracy in the manufacturing process. Also, the automated engineering makes sure the entire steps are fast and quick for on-time delivery.

Solder Pasting:

When you get the PCB at hand, the temptation is high to instantly add the components to it. But, it is not possible and neither is a practical idea. You have to inspect the printed circuit board and add solder where it is essential.

Typically, you have to add the solder on the component pads using the solder screen.

If you don’t know what solder paste is, here’s the short answer-

It consists of flux and small solder grains to form a paste. The deposition of the solder paste on the specific process is similar to the printing process. Firstly, the solder screen will be placed right where you want to add the solder paste. The screen has a hole in it to see through it into the PCB. Then, a runner will move over the solder screen.

Finally, a small amount of solder paste will go through the screen hole and sit right over the PCB substrate. You have to control the solder deposition to ensure that the component pad isn’t clogged with too much of the solder paste.

Pick and Placement Process:

This process has two steps to follow-

  1. Adding the solder paste properly to hold the components.
  2. Passing the entire circuit board into the pick and place process.

The solder paste uses its tension and adhesiveness to accommodate the components right in their positions without movement. Also, you have to ensure that the circuit board isn’t jolted or the components will move and get out of their positioning.

Then, at the final stage, the circuit board passes through the pick and place machine. It has reels holding the components. As the circuit boards pass through it, the reel will correctly position the electronic components on the board. It follows the pre-designed model for each PCBA.

Some machines will add glue in doted form for additional security of the components. It is especially essential for wave soldering. Although the connection between the components and the circuit board is made secure with the glue, it makes any repairing process difficult.

You will have to drive the PCBA design information and program it to the pick and place machine properly. Otherwise, the assembly won’t be accurate.

PCB Manufacturing process

Soldering Process:

Once you have added all the necessary electric components on the circuit board using a pick and place machine, you have to solder them. Our engineers and workers will pass through the component added PCB through the automated soldering machine.

Many manufacturers will use the wave soldering process but these days it has become an outdated process. More importantly, the surface mount components (SMC) aren’t best for wave soldering. Hence, most PCBA manufacturers use the reflow soldering technique.

Note: If the assembly follows wave soldering, it doesn’t need any solder paste processing. The wave solder will add the essential soldering material to the circuit board.

Testing and Feedback:

Once the soldering is complete, the entire assembly of the PCB to its components is thoroughly observed and checked. The manual inspection isn’t a valid option here. The Surface Mount Components (SMC) has hundreds of various components and you can’t manually check them.

FX PCB uses automatic optical inspection (AOI) for the detailed and mostaccurate inspection of the soldered components. There are inspection machines that will check the soldering joints and report where the components need re-soldering.

Finally, the entire PCBA setup is tested before delivery. There are multiple ways and methods for testing the entire PCBA setup. Also, it is essential to monitor the component outputs after soldering. It will decide whether or not the entire assembly process is satisfactory.

The manufacturers use the optical inspection to find if the assembly has any connection failure. Once the inspection is completed and the performance is satisfactory, the PCBA is packed for delivery.

Final Words

In this guideline, we have simplified the PCBA manufacturing process, thanks to our engineering output. The entire process is optimized to keep the defects at the lowest level. Hence, FX PCB follows the standard and exceeds it to offer you the highest-quality PCB and PCBA manufacturing at the most competitive pricing.

What Is PCBA

What Is PCBA? : Its Benefits and Difference with PCBA

PCBA stands for Printed Circuit Board Assembly. Up to this meaning, it’s all fine. But the real problem starts right from here. Many, in fact, most people don’t understand the true meaning and purpose of the PCBA. And many would even confuse it with the PCB.

So, we decided to write on what is PCBA. Of course, it has a close connection with the Printed Circuit Board (PCB). A PCB refers to an electronic pad designed to transmit electronic signals while dissipating the heat generated due to the digital transmission.

And the PCBA refers to the complete electronic board after all of its components are assembled completely. It has several incredible benefits that make it a much sought-after element in the communicating and electronics industry.

However, it has key differences with the PCB. A PCB is void of any electrical components whereas the PCBA refers to the complete board assembly.

What Is PCBA?

A PCB consists of non-insulating and heat-resistant materials. It has a substrate that dissipates the heat to keep the entire setup cool and high-performing. The upper section has conductive materials such as copper to transmit the signal electronically from one part to another.

The substrate is made of different elements and it works to dissipate heat. However, the PCB is an incomplete construction as it doesn’t have the electronic components, not on it.

The PCBA, on the other end, is a complete assembly. You have to assemble the PCB, once it is ready. The assembling requires both passive and active components. The list of these electronic components include-

  • Resistor
  • SMD capacitor
  • Transformer
  • Diode
  • ICs
  • Transmitter

You have to mount these components on the printed circuit board to prepare the fully usable circuit boards. And this assembled circuit board is the PCBA we are referring to until now. Also, note that the electronic components can be of two types. These types are-

  1. SMD components: It refers to surface mount devices. You have to use the surface mount technology to install these components on the PCB. You can identify the SMD components by measuring the number of pins in the package.
  2. Through-hole components: Thru-hole or through-hole components have leads in them. The leads are inserted through the PCB board surface. You have to drill holes on the PCB surface to insert the thru-hole components into it.

The assembly of the printed circuit board is done in two ways. You may opt for automated soldering to mount the electronic components on the PCB. The most popular soldering technology is wave soldering. It is used for the conventional thru-hole components.

Another widespread technology to solder the components on the PCB is the Reflow soldering technique. It is used for SMD components mostly. You may also use mixed soldering technology. Some expert professionals will use hand soldering too. But it is a quite difficult task.

When you complete the soldering or assembling of the electronic components on the printed circuit board, it is referred to as the PCBA or Printed Circuit Board Assembly. Until you prepare the PCBA, the PCB isn’t ready for any application. And when you have prepared the PCBA, you can use it for use on different devices.

Difference Between the PCBA and PCB

PCBA

If you’re involved in the world of electronics, communication device production, or circuit board manufacturing, it’s absolutely crucial to understand the difference between PCBA and PCB. This knowledge isn’t just interesting; it directly impacts your ability to select the correct printed circuit board for your specific needs.

  1. It’s essential to know that they come in a variety of forms, dictated primarily by the material used for their substrate or base. There are metal-based PCBs, known for their robustness and durability. Ceramic-based PCBs, prized for their resistance to high temperatures and high-frequency performance, and FR4 PCBs, made from glass-reinforced epoxy laminate material, are commonly used for their good insulating properties and relatively low cost
  2. In addition to the material choice, PCBs can also differ in flexibility and the number of layers they possess. This adaptability is really handy for gadgets that come with intricate designs or tight space constraints. Conversely, there are rigid circuit boards that stand out for their strength and durability, making them a perfect choice where mechanical sturdiness matters the most.
  3. Circuit boards can be of two types: single-layered (one-sided electronic parts) or dual-layered (double-sided electronic parts). Deciding between the two largely depends on the intricacy and specific needs of the electronic device being designed.

Many manufacturers will outsource the PCB from different companies and finish the PCBA on their own. Also, only a few companies are capable of completing the assembly of electronic components assembly on the PCB.

Nonetheless, you can depend on us to get your PCB and PCBA done. FX PCB with 10+ years of useful experience in printed circuit board manufacturing, we also prepare PCBAs. It will surely cater to your device-making needs.

What To Consider For the Best PCB for PCBA Manufacturer

When you outsource the customized PCB prototype to prepare the PCBA, you have to look at a few factors closely.

  • Manufacturing Printed  Circuit Boards

    When you’re out there hunting for the best circuit board manufacturing company, it’s important that their main business is about creating printed circuit boards and not just being a broker or middleman. A company that just brokers orders may not have the same level of commitment or expertise as the ones that also manufacture circuit boards, which could lead to potential issues with the quality or delivery of the printed circuit boards.

  • No MOL

    Furthermore, a reputable printed circuit board manufacturer will not restrict the number of PCBs you can order, a practice often referred to as the Minimum Order Limit (MOL). The company should give its customer the leverage to order pieces as per their needs. Else, it can restrict customer flexibility and ultimately cause dissatisfaction.

  • Different PCB soldering techniques

    When it comes to PCBA (Printed Circuit Board Assembly) manufacturing, the company should be well-versed in various PCB soldering techniques, such as Surface-Mount Technology (SMT), thru-hole, and hand soldering. These methods each have their specific applications and advantages, and a good manufacturer should have the expertise to choose and execute the right technique for a particular project. This know-how is crucial for ensuring the effectiveness and reliability of the assembled boards.

  • Lead Time

    Lead time, or the time it takes from placing the order to delivery, is another key consideration when selecting a PCBA manufacturer. The company must guarantee timely delivery of the assembled boards, as delays could disrupt your production schedules or product launches. Along with prompt delivery, the manufacturer should also provide a detailed Design for Manufacturability (DFM) report. This crucial document offers recommendations to enhance the manufacturability of your design, helping you avoid potential manufacturing issues and costs down the line.

  • Pricing 

    Lastly, pricing plays a significant role in your selection process. The costs quoted by the PCBA manufacturer should be competitive, in line with the market rates, and subject to negotiation. A rigid pricing structure might limit your ability to maximize the value of your investment. Discussing and bargaining with the manufacturer to achieve the best possible pricing can help you manage your budget while ensuring you get a high-quality product.

Are you wondering where to get a PCBA supplier who puts tick marks in these requirements? Well, FX PCB is here to meet your demands. Our professional engineering and the working team prepares various PCBs and assemble them with electronic components.
