Basic Knowledge of In-Circuit Testing: What is an In-Circuit Tester?
*Free materials available now! A must-see for those who don't know the basics of in-circuit testers that you can't ask about anymore!
To ensure that electronic devices function correctly, the electronic circuit board within the device must operate normally. The electronic circuit board operates when electronic components are correctly mounted on a printed circuit board (PCB) and power is supplied. The inspection of the electronic circuit board in the state where these electronic components are mounted is called In-Circuit Testing (ICT). An in-circuit tester is a testing device aimed at checking the connection reliability between electronic components and the board, as well as detecting component errors. By inspecting the values of individual electronic components (such as resistors and capacitors) and diode characteristics with minute electrical signals, the board can be tested for quality without imposing unnecessary loads on it. It is also referred to as MDA (Manufacturing Defect Analyzer). Main inspection items: ● Solder shorts and opens ● Pattern disconnections ● Missing components ● Incorrect component values ● Reverse insertion of polarized components ● Lifted leads of ICs and connectors ● Operation verification of digital transistors, optocouplers, and Zener diodes ● Other simple function tests
