Hardware checker module

Debugging hardware (ex. Device-Interface-Board or DIB) is very difficult especially if it is not your hardware design or set-up problems during production. ATE has their own checker to identify the problem of the instruments cards. Is your own designed test hardware or production released hardware has its own checker? If none, then you need a hardware checker module. A hardware checker module helps engineers/technicians to easily identify the problem of a typical set-up. The module consists of either a checker program or a resistor-insert or both. A checker program can be developed either an open loop or a closed-loop (with resistor-insert). It can also be a stand-alone program or embedded on the production released FT/WS program. The benefit of this practice is faster debugging. Faster debugging means faster cycle time to release of a new or down/defective hardware. It will also benefit manufacturing OEE. It will help identify the problem of the set-up either ATE or test hardware.
