ABSTRACT:
Apparatus for the automatic inspecting, programming and testing of programmable read-only memory (PROM) devices. Under computer control, this PROM Handling System will test a sequence of PROMs against new part specifications, program them in any sequence of bit patterns required by the next piece of machinery on the assembly line, mark the PROM with a four digit part number identifying the bit pattern contained therein, dry the ink in a heated chamber for a fixed amount of time, dynamically test each PROM bit for access time in a hot and cold environment, program and test replacement PROMs for the ones that had failed at any point in the process, sort the PROMs into the correct order as required by the next assembly line machine and output said tested and ordered parts into output sticks for manual delivery or automatically deliver them by a track arrangement to the next machine. The programming apparatus can produce any type of electrical programming pulse and can test the device's access speed through the use of programmable circuitry which can be automatically reconfigured by the computer to accomodate the various vendor specifications.
