Research Quality: 50% complete

The Rasco SO 1000 is a tri-temperature handler for semiconductor packages such as SSOP, SOIC, and TSSOP. The Rasco SO 1000 uses LN2 for cold temperature testing. The Rasco SO 1000 operates on a 230 V, 2300 W power supply and requires 5 to 10 bars of compressed air.[1]

What it is

General reference — not yet source-verified

Semiconductor test handlers are automated machines that transport packaged integrated circuits to a test station, where they are electrically tested and then sorted into bins based on test results.

How it works

General reference — not yet source-verified

A handler picks individual devices from input trays or tubes and places them onto a test track. The handler indexes each device through a temperature conditioning zone to bring it to the required test temperature. At the test station, the handler presses the device contacts against a test head that connects to an automated test equipment system. After testing, the handler sorts the device into an appropriate output bin based on the test result.

Where it fits in the process flow

General reference — not yet source-verified

The handler is used in the final test stage of semiconductor manufacturing, after packaging and before device marking and shipment. The handler receives packaged units from the assembly line and delivers them to the test floor, where they are electrically characterized. After test, the handler outputs devices to tubes, trays, or tape-and-reel for downstream processes or shipping.
