Introduction to the basics of electronic components in PCBA process


Electronic components are part of small machines and instruments.Besides, almost all electronic circuits and PCBA processing are inseparable from electronic components, which play an important role.This shows that electronic components play a very important role in the circuit and electronic products. In this article, we will take a comprehensive look at the various aspects of electronic components.

What are electronics components?

What-are-electronics-componentsElectronic components are fundamental parts that are utilized to produce electronic circuits, which in turn generate an electronic device that can carry out the specific task for which it was designed. These electrical components, which are available in single-unit configurations, are used to regulate the movement of electrons so that the user can create the circuit of their choice.

Electronic components are extremely affordable and portable, and they are very small in size. These parts have two or more terminals that are utilized to link with a wire, which in turn joins all of the discrete small electronic parts into a circuit with a specific function usually on PCB through PCB soldering. There are several sorts of electronic components that can be categorized, however electronic components are distributed into three main classifications.

What are the 3 classifications of electronic components?

Electronic components fall into one of three primary groups: passive, active, or electro-mechanic components.

Passive components

Electronic parts that can only receive energy and then dissipate, absorb, or store that energy as magnetic or electric field are known as passive components. Passive electronic components can affect the flow of electricity going through them but cannot amplify or regulate it because they do not use any energy source except the AC circuit to which they are connected. These parts mostly consist of two-terminal devices like capacitors and resistors.

Active components

Active components in electrical devices work as an AC circuit as they can amplify electric signals and produce power, unlike Passive electronic components. Active electrical components can carry out their specific function as they consume energy, and the direct current circuit serves as the source of this energy. Majority characteristic active components consist of an oscillator, transistor, and integrated circuit.

Electro-mechanic components

Electromechanical components are those type of electronic components that use electric current to perform a mechanical task. Usually, to produce movement, these components utilize electrical current to produce a magnetic field. These components can make use of a wide range of switches and relays.

What is an example of an electrical component?

What-is-an-example-of-an-electrical-componentThere are many electronic components, and they are all distinctive from one another. An excellent example of an electronic component is a resistor, which is frequently used in electronic circuits. Resistors are employed in circuits, as their name suggests, to prevent the flow of current. Each resistor has a particular resistance value, which indicates the maximum amount of current it can withstand.

While diodes are used in electrical circuits to allow current to flow only in one direction and avoid backflow, capacitors are also passive electronic components that are used to store charges in electrical circuits. Transformers, inductors, and other components are other examples of electronic parts.

Why are electronic components important?

As technology develops, electronic devices become more and more indispensable to everyone since they make daily life easier. All electronic devices are made by combining electronic components in a way that allows the device to perform a specific set of tasks. Electronic components are crucial in today’s world because electronic gadgets are widely used in industries and for personal use and producing them can have an impact on a nation’s GDP.

Electronic devices cannot be produced without the use of electronic components. In essence, this means that electrical components are more essential than ever in today’s environment.

How do I identify electronic components?

There are many various types of electronic components, and since each one serves a distinct purpose, it is necessary to check for each component’s distinctive markings on the body or on the package in order to distinguish between them. Component number, value and tolerance, polarity, and color-coded bands to denote resistance are all included in the particular mark or code. A component can also be identified by using digital multimeter tests.

How many components are in a PCB?

The various electrical components that make up Printed Circuit Boards and they all are essential to the operation of the device to which they will be attached. A specific circuit is created by connecting the seven electronic components that make up a PCB. Included in these seven electronic components are
● Resistors
● Inductors
● Diodes
● Transformers
● Sensors

How are components connected in a PCB?

All of the electronic components are connected via traces on PCBs, which are used to join them all together to form an electronic circuit. They communicate with one another by sending electrical impulses through the traces that link them together.

How do you test electronic components in PCB?

To ensure that the electrical circuit designed works properly, electronic components in the PCB should be tested. A digital multimeter should be used to test the components. The knob of the instrument should be oriented at the appropriate unit for each component, and the two probes should be put on the component’s terminals. The component is functioning properly if the outcome is near to the calculations done; else, it is defective.

How to choose a best electronic components manufacturer?

It can be challenging to find the best manufacturer for electrical components, but you can be sure of it by choosing a manufacturer who complies with all legal and quality criteria. They should get their products ISO-certified for quality. The customer reviews can provide you a thorough understanding of the manufacturer. The ideal option is to go with a renowned and trustworthy manufacturer who offers parts at reasonable prices and is accessible. The supplier must provide the electronic components on schedule. These factors will all help to ensure that you are buying from the right supplier.
