What tests are usually essential for electronic components?

What are electronic components?

Electronic components are referred as parts to develop electronic, radio, or electrical devices.

Electronic components include transistors, capacitors, diodes, potentiometers, resistors, inductors, connectors, electron tubes, electromechanical components, heat sinks, semiconductor discrete devices, electronic display devices, electro-acoustic devices, switches, power supplies, laser devices, optoelectronic devices, microphonics, sensors, crystal, quartz, piezoelectric, ceramic magnetic materials, varied circuits, printed circuit boards, electronic transformers, integrated circuits, relays, printed circuits with substrate substrates, electronic chemical materials and components, electronic adhesive (tape) products, electronic functional process special materials, etc.

What is the history behind the development of electronic components?

The invention of electronic components marks the advent of the electronics sector. Between the end of the nineteenth century to the beginning of the twentieth century, the electronics sector started developing rapidly. This is where the electronic components were used widely that marks the beginning of modern science and technology development.

In 1906, Lee De Forest, the American Scientist, invented the electron tube (vacuum triode). The electron tube acts as the core to develop the first-generation electronic products.

At the end of the 1940s, the first semiconductor transistor was invented. It had the following features such as - small size, portable, long life, power-saving, lightweight, etc. This transistor replaced the use of electronic tubes quickly in a widespread range.

At the end of 1950s, the scientists developed the world's first integrated circuit. It integrates various transistors and other electronic components in a silicon chip. This development has marked the advent of miniaturized electronic products.

Later, these small-scale integrated circuits quickly developed into large-scale and ultra-large-scale. The aim of this transformation is to develop highly qualitative electronic products with greater efficiency, improved precision, lower consumption, improved stability, and better intelligence.

Hence, these are the four stages of development in electronic technology in four eras that lead to the invention of computers as well.

When it comes to the 20th century, there was a rapid development of the electronic components industry. It’s because these components were used in all the electronic products that we use.

What are the tests to be done for electronic components?

The quality test of electronic components is the mandatory step that determines their efficiency and accuracy. This testing helps to predict whether these components are working normally or not.

Here are the three major types of testing electronic components:

1. General test

This is the preliminary test used to check the size, appearance, performance, and safety of electronic components.

Other basic parameters such as pin pull, pin bending, resistance to soldering heat, HFE, VCEO, ICBO, VCES, RoHS, etc. are also checked according to the user’s requirements.

2. Reliability test

This reliability test helps in determining the life span as well as the environmental test of electronic components.

Other basic parameters such as low temperature test, high temperature test, durability test, vibration test, moisture test, maximum load test, etc. are also checked according to the user’s requirements.

3.DPA analysis

This DPA analysis is used mainly to check the internal size and structure of the device as well as its process control.

What is the best inspection method for electronic component testing?

There are various inspection methods to test the internal structure and packaging procedures. The list includes X-ray inspection, acoustic scanning monitoring, open monitoring, etc.

Among them, X-Ray real-time imaging technology is used widely due to its features like quick, easy to use, non-destructive, relatively low-cost, etc.

A good PCB X-ray inspection machine can successfully test the internal components, such as solder ball (lead), chip layout, lead frame design, lead arrangement, etc.

If the components are complicated, it is possible to adjust the angle of the X-ray tube, current, voltage, image brightness, and image contrast of a good PCB X-ray machine to get a high-resolution image.
