Five test methods of PCBA.


PCBA process is complex. In the production and processing process, various problems may occur due to improper equipment or operation, which can not guarantee that the products produced are qualified. Therefore, PCBA test is required to ensure that each product will not have quality problems.


PCBA test mainly includes five forms: ICT test, FCT test, aging test, fatigue test and test in harsh environment.

1.ICT test: including on-off, voltage and current values, fluctuation curve, amplitude, noise, etc.

2. FCT test: it is necessary to burn ic program, simulate the function of the whole PCBA board, find problems in hardware and software, and equip necessary production fixtures and test racks. This test requires the functional description provided by the customer and the support of the customer tester to complete this test

3. Fatigue test: sample the PCBA board, operate the function at high frequency and for a long time, observe whether there is failure, and judge the probability of failure in the test, so as to feed back the working performance of Printed Circuits Board in electronic products.


4. Testing in harsh environment: the PCBA board is exposed to the temperature, humidity, drop, splash and vibration of the limit value to obtain the test results of random samples, so as to infer the reliability of the whole batch of PCBA board products.

5. Aging test: power on PCBA board and electronic products for a long time, keep them working, and observe whether there are any failure faults. Electronic products after aging test can be sold in batches.

This is all for PCBA test form today. I hope it will be helpful to you.
