DFT for In-Circuit Test: When Should Testing Be Considered

February 6, 2019

The success of the manufacturing process is based upon the execution and measurement of the health of each process step. The machines on assembly lines install thousands of parts every minute; therefore, throughout the assembly process, checks must be completed. DFT allows capability for testing which includes component connectivity, electrical value, and proper component orientation. However, final testing—in-circuit testing capability—must be designed into the PCB at the layout stage.
