Abstract
A system for connecting a test pin of automatic test equipment (ATE) to devices for testing includes a first handler for manipulating a first portion of the devices and a second handler for manipulating a second portion of the devices. The system includes a first socket for testing devices of the first portion, which is connected to a first wire, and a second socket for testing devices of the second portion, which is connected to a the second wire. A controller multiplexes the two handlers, or dual manipulators of a single handler, to operate the handlers asynchronously in coordination with testing, such that while the ATE is testing devices for one handler, the other handler presents next devices to the ATE for immediate switch of testing between devices for each handler. The system is suitable for conventional handlers and ATE.
