ABSTRACT:
An LED array module for use in an LED array printhead is fabricated on a frame of tape-automated bonding (TAB) tape that provides all of the wiring for connecting the chips together, for connecting the module to one or more external circuit boards and for testing the module; thereby protecting the delicate components and allowing the module to be completely tested prior to excising it from the TAB frame and mounting it to the printhead support member.
