Pass Marking Unit

A device which, upon receipt of a test pass signal, will scribe a permanent circular mark onto the unit under test

The BMP-1 test pass marking unit is intended for installation into test fixtures and production equipment. Upon receipt of test pass signal it will rapidly scribe a permanent circular mark onto the unit under test removing the risk of human error. This compact unit requires a footprint of less than 15mm square on the test board. The spring loaded carbide tip is longlasting and its hardness will mark bare fibreglass (FR4), solder mask over glass or copper, bare tinned copper, plastics & metal castings. The BMP-1 is supplied with a mounting receptacle with knurled fitment, cables and a plug/socket kit allowing easy connection to the jig’s internal wiring. The scriber can easily be unscrewed from its receptacle so it can be transported for use in other positions. Extra receptacles, an insertion tool and tip replacement parts are available as spares and these are listed within the specifications.
