High Frequency PCB

High Frequency PCB

Hello folks, I sincerely hope you all are having a good time and enjoying your life. So, today, we have come up with an essential piece of write up for you. During our long career in PCB (Printed Circuit Board), we have seen many people with increasing confusion on High-Frequency PCB.

The confusion comes mainly from materials used to manufacture the various types of high-frequency PCBs and the benefits they bring in particular sectors.

So, we are going to prominently shed light on the same topic.

What is High-Frequency PCB?

As we all understand, PCB is an acronym for Printed Circuit Broad. It uses copper to create a conducive pathway. The copper is attached to the substrate material made of resin.

Similarly, high-frequency PCB uses the conduciveness of the copper material to enhance the performance.  The breakthrough technology is widely applied in various applications. It is a developing tendency for uses in radio frequency, mobile phone, microwave, and even in the newly developed high-frequency applications.

Now let’s see the laminates and bonding sheet used for the PCBs with high-frequency conduciveness and their benefits.

Types of Laminates and Bonding Sheet

When it comes to building substrates for PCB along with the bonding sheet, you will find two reliable and prominent manufacturers in the industry. They are SY and Rogers.

Both manufacture a wide range of laminates and bonding sheets necessary for the best PCBs. There are sincerely a few things you need to look at for the laminates and bonding sheets’ effectiveness.

First off, you should consider the resin. The resin is used to connect the copper coin with the substrate of the PCB. There are several kinds of resin that manufacturers use for the laminates. The most common resins are epoxy, Teflon, and hydrocarbons.

As you see in the table, there are three types of laminates that the manufacturers are using for Printed Circuit Boards. These are-

  • FR4
  • R04350B
  • R03003

We all discuss the details about them in the following sections.

Next, we would like to draw your attention to the DF and DK factor of the PCBs. Both DF and DK need to be smaller since high DF and DK might delay the signal processing time. The efficiency of DF and DK is further attributed to the water absorptivity. It also must be lower since high-absorptivity of water affects the DF and DK in wet conditions.

Now take a look at the table to see all these factors and choosing the right one you need for specific applications.

Our Standard Inventory

Here is the standard product inventory we have to offer for you. As you might guess, our list comprises of all the quality PCBs for high-frequency efficiency.

You just need to ardently pick the right one for your requirements. But if you want to know detailed about them, then look at our description in the following sections.

So, let’s begin it.

The R04350:

The R04350 high-frequency PCB material comes from the Series 4000 from Roger. It is manufactured using ceramic or hydrocarbon laminates that ensure stability on the substrate.

Rogers has designed the R04350 for enhanced performance sensitivity with high-volume applications. It has low dielectric tolerance. Also, every PCB material made from Rogers’ 4000 Series has incredible low-loss efficiency.

So, the R0400 Series is ideal for use in broadband applications. Some other typical and widely used applications of Series R04000 are described in the following parts:

  • Stationary antennas for cellular-based networks.
  • In extensive power amplifiers
  • Identification tags for RF markers.
  • Advanced sensors and radars used in the automotive industry.
  • Direct broadcast satellites use R 4000 Series for LNB’s.

The wide range of PCB applications is made possible for several incredible benefits the R04350 Series brings on in the practical usage. These benefits are:

  • It has a low-thermal co-efficiency.
  • It remains stable and sturdy for a temperature range while working with various circuit processing.
  • Rogers uses standard epoxy glass procedure to fabricate the R0400 Series, which is the successor of our R04350 lamination used in high-frequency PCBs.
  • The lamination has a brilliant electrical performance.

Since the lamination process has a fantastic range of applications and benefits, we have included three various lamination types from the R04000 Series.

Now take a look at these laminations. Our first product is a combination of R04350 and copper hybrid. It brings all the benefits of the R0400 Series and blends them expertly with the copper coin board. The hybrid copper has enhanced conduciveness that makes the signal transmission much faster and fluid. We have also introduced a cost-cutting version of the reliable and consistent R0400 Series in the form of the R04350 Hybrid. It has almost every benefit and application of the Copper Hybrid but comes in a cheaper price tag. The last one in our list from the R0400 Series is a low loss R04350 lamination. Its low loss performance makes it ideal for use in the broadband application. Also, it has enhanced performance ratings too.

The R03003:

R03003 Series provides consistency when it comes to mechanical properties. It largely remains unaffected by the DK (Dielectric) you select for the lamination. So, designers can create multiple layers of high-frequency PCBs where every layer has its own DK rating.

The benefits of R03003 include:

  • The DK range varies from the lowest 3.0 to the highest 10.2 offerings perfect selection.
  • The lamination is available ardently with or without the updated woven glass reinforcements.
  • The Z-axis CTE is lower enough to provide reliable plated through holes creation.
  • The laminates have the lowest loss in practical usage.

It has a broader application that you may not aware of consciously. Some useful applications are listed below.

  • Handheld Wifi and cellular antennas
  • Backhaul radios
  • Communication systems
  • Infotainment and telematics.

Since the R03003 Series brings such fantastic benefits and applications, our inventory covers two popular types of lamination from the same Series. The hybrid R03003 is an advanced high-frequency PCB with lower cost. So, it fits your budget with ease without compromising the quality, benefits, and applications. It also has a broader range of applications with extreme benefits. So, it will come in handy in its respective application area.


We now sincerely hope that the descriptive article has cleared your confusion on high-frequency PCBs. Now it is your ardent turn to choose the right one that matches your business style and applications.
