BMP – 4
ECT’s BMP-4 Board Marker Probe is designed for installation on bare board or loaded board test fixtures. When your tester is equipped with the appropriate electronics and software, the BMP-4 scribes a permanent circle on every “passed” PCB or device tested. Boards that fail the test are not marked. The risk of human error is eliminated in PCB testing and sorting.
When activated, the spring-loaded scribe tip contacts the PCB surface. The 12 V DC motor rotates the scribe in a counter clockwise direction and leaves a .050” (1.27mm) circle mark onto the PCB. The probe requires less than .400” (10mm) of fixture area when mounted into a threaded hole. It’s designed to mark board areas comprised of bare glass (FR4), solder mask over glass, copper, or bare tinned copper.
