PCBA (PCB assembly) refers to the process of mounting, inserting and welding the bare PCB board. The circuit boards we usually see are welded with components on the basis of PCB, namely PCBA, and PCB is "bare board" and "light board". Generally speaking, PCBA reliability test is divided into ICT test, FCT test, fatigue test, simulated environment test and aging test. Because the problem of any material will affect the overall result of PCBA board, which requires us to have sufficient material detection ability, supplier management ability, technical analysis ability and reliability testing ability.

PCBA reliability test

1. ICT test

ICT test is mainly the test of component welding, on-off of circuit, voltage and current value, fluctuation curve, amplitude and noise.

2. FCT test

The FCT test needs to burn the IC program, then connect the PCBA board to the load, simulate the user input and output, test the function of the PCBA board, find the problems in the hardware and software, realize the joint debugging of software and hardware, and ensure the normal manufacturing and welding of the front end.

3. Fatigue test

The aging test is mainly to sample the PCBA board, simulate the high-frequency and long-time operation of the function used by the user, observe whether there is failure, and judge the probability of failure in the test, so as to feed back the working performance of PCBA board in electronic products.

4. Simulated environment test

The simulated environment test is mainly to expose the PCBA board to the temperature, humidity, drop, splash and vibration of the limit value, and obtain the test results of random samples, so as to infer the reliability of the whole batch of PCBA board products.

5. Aging test

Aging test is a long-term power on test of PCBA board to simulate the use of users, keep it working and observe whether there are any failure faults. Only after aging test can electronic products be sold in batches.

I believe that by reading the above content, you have a preliminary understanding of the reliability of PCBA.
