PCB Testing Methods

Printed circuit boards are found in many of the devices we use at home. Unfortunately, very few people understand the technology behind them. As a result, we must understand what electronic components are and what they do. This is critical for anyone interested in knowing how PCBs work and their application. This post looks at some of the Circuit Board Components used to make PCBs.

Resistor

It is one of the most critical components of PCBs. It is used to control voltage and the current flowing through a circuit.

We use a resistor to control the voltages and the winds in a course. If connected in series with a load, it can control the current flowing through the circuit and reduce the chances of the bag burning out.

Capacitor

The component is mainly used to stabilize the voltage supplied to a circuit. It behaves like a battery that can store charges and introduce some time delay in the course.

Capacitors can be divided into polarized and non-polarized capacitors.

Light Emitting Diode (LED)

It is a component that gives light and can give visual feedback from a circuit. It can be used to make fantastic light show circuits. Diodes allow current to flow in one direction.

Transistors

It acts like a switch that is controlled by an electrical signal. Transistors can be used in amplifiers since they amplify charges.

Inductor

It is a coil of wire that is used as a filter.

The work of an inductor is to stop the change of current and store charges.

An integrated circuit

It consists of an electrical circuit that has been shrunk to fit on a chip. It could be an amplifier, a microprocessor, or a USB to a serial converter.
