Program burning→ICT test→FCT test→aging test
1, program burning
After completing the welding process of the front end of the PCBA board, the engineer began to program the microcontroller in the PCBA board to enable the microcontroller to achieve specific functions.
2, ICT test
ICT test mainly uses the test probe to contact the test point of PCBA to realize the test of PCBA circuit open circuit, short circuit and welding condition of electronic components. The accuracy of ICT testing is relatively high, the instructions are clear, and the scope of use is relatively wide.
3, FCT test
FCT test can test the environment, current, voltage, pressure and other parameters of PCBA. The content of the test is relatively comprehensive, which can ensure that the various parameters of the PCBA board meet the design requirements of the designer.
4. Burn-in test
The burn-in test can ensure the stability of the product by continuously energizing the PCBA board, simulating the user's use scene, detecting some hard-to-find defects, and inspecting the service life of the product.
After a series of PCBA tests, the PCBA without any problem can be labeled with a qualified PCBA, and finally it can be packaged and shipped.
