Functional Test
Category: Testing
Description: Functional test (“FCT”) is typically performed in the last phase of the production line of a product, as a final quality control by emulating or simulating the operational environment of the product in order to check its correct functionality. Unlike
InCircuit Test which uses test points on the PCB, Functional Test uses the PCB connectors for test software to communicate between the PCB and external programmable instruments.
Major Cost Drivers -- PCBA Functional Test
Functional Test Cycle Time is a factor of the planned functional test time and the test yield.
Process Time = Functional Test Time*( Functional Test Yield/100)
Functional Test Time =(PSO)
