The Main Process of PCBA Testing

June 02, 2022

PCBA testing refers to the testing of IC programming, circuit continuity, current, voltage, pressure and other aspects of the PCBA board. There are many uncontrollable factors in the production process of PCBA. It is difficult to ensure that the PCBA is an intact product. PCBA testing is a necessary link to strictly control the quality of shipments.

PCB test

PCBA test generally formulates a specific test process according to the customer's test plan. The basic PCBA test process is as follows:
Program burning→ICT test→FCT test→aging test

1. Program burning
After the PCBA board completes the front-end welding process, the engineer begins to program the microcontroller in the PCBA board, so that the microcontroller can achieve specific functions.

2. ICT test
The ICT test mainly realizes the test of the circuit open circuit, short circuit and the soldering of electronic components through the test probe contacting the test point of the PCBA. The ICT test has high accuracy, clear instructions, and a wide range of uses.

3. FCT test
The FCT test can test the PCBA's environment, current, voltage, pressure and other parameters. The content of the test is relatively comprehensive, which can ensure that the various parameters of the PCBA board meet the designer's design requirements.

4. Aging test
The aging test can ensure the stability of the product by continuously energizing the PCBA board, simulating the user's use scenario, detecting some difficult-to-find defects, and inspecting the service life of the product.

After the PCBA has undergone a series of PCBA tests, the PCBA board without problems can be labeled as qualified, and finally can be packaged and shipped.
