  • Patent number: 5313156
    Abstract: An integrated circuit (IC) device test handler which is adaptable to receive various customer tray configurations and automatically test the ICs within. The test handler comprises a customer tray magazine input area, a load section, a soak chamber, a test section, an unsoak chamber and an unload area. Two magazines containing customer trays with IC devices are input to the handler. An elevator mechanism raises the customer trays within one magazine at a time to a position which can be accessed by the loader of the test handler. A catcher device moves the trays to a buffer platform where the trays can be accessed by a transfer arm. The transfer arms moves the customer trays to one of two load stages. A pick and place apparatus removes the IC devices from each customer tray on the load stages and transfers them to a precisor for alignment and then to a test tray.
