Method and system for synchronizing lead scanners and laser marker modules

Abstract

A method and system for synchronizing a laser marking device with a lead scanner is disclosed. The laser marking device includes an unloader coupled to the lead scanner and is for marking each of a plurality of semiconductor packages including a plurality of leads. The lead scanner performs a test on the plurality of leads for the plurality of semiconductor packages. The unloader is for containing a portion of the plurality of semiconductor packages that passed the test. The method and system include providing an input receiving circuit, a reset circuit and an output relay. The input receiving circuit is coupled with the unloader and is for receiving an indication of a particular number of the plurality of semiconductor packages received by the unloader. The reset circuit is coupled with the lead scanner and the input receiving circuit and is capable of generating at least one reset signal for resetting the lead scanner in response to the particular number of the plurality of semiconductor packages being reached. The output relay is coupled with the lead scanner and the reset circuit. The output relay is for temporarily precluding the lead scanner from providing a semiconductor package to the unloader.
