How the PCBA Functional Tester Works?
PCBA functional tester can also be called a Test fixture or test jig, and it is a highly efficient but simple principle. It uses metal probes to connect the pad or test point on the PCB. When the PCB is powered on, the tester can get the PCB voltage, current, and other values from the test circuits
These values are monitored via ammeters, voltmeters, or automated test equipment to determine whether the circuits are working properly. This principle forms the foundation for subsequent testing methods, including ICT (in-circuit test) and FCT (Functional circuit test)
Why we need to use the PCBA function tester?
Firstly we need to know FCT-PCBA functional testing is a kind of simulated test after the PCBA production is finished, and this test needs to program the IC to verify the entire PCBA board function, then you can find the potential hardware and software issues. So any problems detected during testing can be reported to the design and production departments in time, and the problem can be solved accordingly. To complete the PCBA function test, you need to use the tester to complete it.
How to make the PCBA function tester?
1, PCBA files: PCBA factory will send the PCBA board, PCBA Gerber file, and test requirements to the tester factory.
2, Design the PCBA function tester: The tester factory will make the design for the test fixture based on the structure, connection, position and etc.
3,Material preparation: The PCBA test fixture uses acrylic, bakelite, plastic, metal probes, display screens, wiring, and a simple circuit board to manufacture.
4, Manufacturing Process: Produce the PCBA function tester by drilling, cutting, and assembling the material per the drawing.
5， Calibration &Verification: Once the tester is assembled, we still need to calibrate and verify the test jig to confirm compliance with test specifications, ensuring reliable accuracy and stability.
When we make the PCBA function tester, we should do some protection to avoid damage to the test board. Meanwhile, the smooth connector mating and accurate transmission of testing are very important, and it also needs to be designed to accommodate various testing requirements and ensure the PCBA testing equipment will be easily operated and maintained.
How long can the PCBA function tester be done?
The PCBA function tester’s production time is hard to give the exact delivery time, as the simple one can be finished in several days, and the complicated one may need several weeks. You can confirm the delivery time with your PCBA supplier after discussing the requirements.
