What Kinds Of PCBA Testings Forms?
Apr 10, 2018

What is the PCBA testings?


The PCBA process is complex. During production and processing, various problems may occur due to improper equipment or operation, and it cannot be guaranteed that the produced products are all qualified. Therefore, PCB testing is needed to ensure that each product will not have quality problems.

For PCBA testings there mainly includes five types: ICT test, FCT test, aging test, fatigue test, and harsh environment test.


1. ICT tests mainly include on-off of the circuit, voltage and current values, and fluctuation curves, amplitude, and noise.


2. The FCT test requires IC program firing to simulate the function of the entire PCBA board, find problems in the hardware and software, and equipped with the necessary patch processing fixtures and test frames.


3. The test under harsh environment is mainly to expose the PCBA board to the limit values of temperature, humidity, drop, splash, and vibration to obtain the test results of random samples, thus inferring the reliability of the entire PCBA board batch product.


4. Fatigue testing is mainly on the PCBA board sampling, and the function of high-frequency, long-term operation, observe whether there is failure, determine the probability of the test failure, in order to feedback the performance of PCBA board electronic products.


5. The aging test is mainly to electrify the PCBA board and electronic products for a long time, keep their work and observe whether there are any failure failures. After the aging test, the electronic products can be sold in batches.
