Types of components of an electronic board

The most used methodology for wiring in the construction of electronic circuits is the printed circuit board. This is normally made of a material called fiberglass that is reinforced with epoxy resins, a thermosetting polymer that becomes hard on contact with a catalyzing agent.

This card is subsequently covered, either on one or both sides, with a copper coating that will then be removed with a photochemical process. Why is this done? In this way we get that only the tracks we need on the circuit remain on board.

In each electronic board we can also find a series of components that will always be present and whose correct assembly depends on the operation of electronic devices.

The types of components that we can find are the following:

Resistors

These electronic elements have the ultimate goal of putting barriers to the passage of electric current through them. The most important characteristic of these is their ohmic resistance, which is given by the physical qualities of the materials present in their composition and which means that their values ​​remain unchanged for both direct and alternating currents.

Another of their peculiarities is the maximum power at which they can dissipate you, depending on their physical construction.

Resistors can be fixed or variable depending on their resistive value.

Capacitors

It is a passive device , used in electricity and electronics , capable of storing energy by sustaining an electric field. Its composition is as follows: two parallel metal frames that are normally made of aluminum, separated by a dielectric material.

Transistors

Transistors are devices that regulate current or voltage flows in an electronic circuit, acting as switches and/or amplifiers of electrical or electronic signals.

Diodes

These elements are also known as rectifiers, since they carry out the transformation from an alternating current to a pulsating direct current. Diodes are semiconductor mechanisms that act as unidirectional current switches, classified according to type, voltage and current capacity.

The reels Placement on Printed Circuit Board

 

Inductors or coils are passive components with the ability to store energy in the form of magnetic fields. They are formed by a hollow coil head of a conductor made mainly of two materials, enameled copper wire, or thread.

The switches

The switches are positioned in an electronic circuit controlling the flows of electricity, stopping the circulation of electrons allowing switching on/off. Its operation depends on whether if they touch a metal contact, being closed when yes and open when not.

The fuses

A fuse cuts off the passage of electrical current by burning the filaments or metal sheets of which they are composed. Its location in an electrical circuit is at the beginning, avoiding that if its current increases it reaches the circuit ruining the device.

What are different types of PCB Components in 2022?

PCB components are available in many different types to control and regulate electrical flow through a specific circuit. Resistors, capacitors, diodes, transistors, and integrated circuits (ICs) are the most common of all components used in almost every electronic device, from a cell phone to a portable radio. These components must be placed in strategic positions along the surface of the printed circuit board (PCB) to create a useful electronic circuit.

Circuit boards contain insulators and other tiny electronic components.

A resistor is a tubular component that typically has specifically colored stripes along its outer surface. Its main purpose is to prevent excessive electrical current from entering the circuit area. Each resistor can only stop a certain amount of current, based on the component’s resistance rating.

The outer stripes signify a resistance values that assemblers reference when building a PCB. Improperly placed resistors can result in damage to other components on the circuit board from high current flows.

Circuit boards include an insulated board equipped with electronic components that have been soldered together.

The Role of Capacitors

Capacitors look like small cylinders that normally protrude from the surface of a PCB. These PCB components use the cylinder to store electrical current; the capacitor allows some current to flow out of the storage area to create a stable power supply for the rest of the PCB.

The electronic device may not function properly if the capacitors are placed incorrectly.

As a result of poorly placed or incorrectly placed capacitors, the electrical flow through the device circuits can have large variations that cause component failure.

Diodes protect the direction of flow of electrical current

Diodes protect the direction of flow of electrical current through PCB components. Since current flows in and out of the diode component, the electric flux cannot reverse direction through the same diode. The component’s internal design forms a barrier to reverse current flow; this obstacle is especially useful for protecting sensitive microchips that can easily fail due to excessive electrical flows.

Transistors are printed circuit board components that can amplify electrical current or switch it to a different part of the circuit. They usually have three legs that connect to the PCB instead of the typical two-leg design.

Electricity can be multiplied inside the transistor and directed to a specific region of the circuit. It can also change the direction of current flow to power a different circuit area, such as when buttons are pressed on a television remote.

Conclusion: 2022 Best PCB Board Manufacturing at FXPCB China

Integrated circuits are essentially small PCBs inside a tiny microchip. These square PCB components have allowed electronic devices to become smaller as more circuitry can be contained in a smaller package. As a result, remote controls and cell phones have become progressively smaller over time.

A resistor is an electronic component that can decrease the voltage of a circuit and its flow of electric current, and a capacitor is a component that can store electrical charges.
