What Is a Functional Tester?
A functional tester is a device that performs a functional test to determine whether an electronic board works properly.
Electronic control of any device is achieved by incorporating electronic boards. The safe and correct operation of a device is verified by first inspecting the electronic board for defects.
There are two types of electronic board defect inspection: off-board inspection and functional inspection.
- Off-Board Inspection
Inspection of whether the components on the board are properly installed without defects. Also called board inspection or mounting inspection. Board visual inspection equipment is used. - Functional Inspection
Inspection of the actual proper operation of the device after the off-board inspection.
Functional tester is used to perform this functional inspection.
Uses of Functional Testers
Functional testers are used to verify that the electronic board for which a functional test is performed outputs the expected behavior when input signals are sent to it.
Since the output behavior differs for each electronic board, it is important to select functional testers that matches the expected behavior.
For example, a power supply board is tested to see if the expected voltage and current flow when the board is switched on, and an LED lighting test is used to see how much output the corresponding LED lights up in response to the input current.
In recent years, general-purpose functional testers that support various types of boards have become available.
Principle of Functional Testers
In function testing, the board to be tested is attached to functional testers to see if it actually works.
To operate an electronic board, an actual operating current is applied to induce the output operation.
Therefore, if the board has soldering defects, the board itself may be damaged due to a short circuit within the board.
Therefore, it is important to carefully inspect the board appearance to ensure that there are no mounting defects prior to functional testing with functional testers.
The functional testers only tests whether the board can actually output operation, which is distinguished from a detailed inspection of the electrical characteristics of each component (resistance values, diode characteristics, etc.).
In this case, it is called in-circuit testing and is performed by energizing a current that is much weaker than the operating current.
These are sometimes combined, and many general-purpose functional testers has built-in function to perform in-circuit testing.
