As a final manufacturing step of PCBA,function test(FCT) provides a pass/fail determination on finished PCBA before they are shipped to customer.A purpose of FCT in manufacturing is to verify if the hardware has any defects,otherwisre,it will bring bad influence for the product function in in a system application
In a word,FCT can validate a PCBA’s functionality and behavior. It is important to emphasize that the requirements of a functional test, its development, and procedures vary widely from PCBA to PCBA and system to system.
During the bare PCB production, E-test and flying-probe test are necessary.
Besides laser test for chips, AOI and Eye-test, after the assembly process we test the boards according to customer's request. Only if you offer the test file, the test could be done.
