SYSTEM AND CASSETTE FOR TESTING SEMICONDUCTOR CHIP

摘要

PURPOSE: Provided is a technique for effectively testing and transporting IC chips with a carrier tape. CONSTITUTION: A cassette(20) for transporting and testing semiconductor IC chips(14) comprises a tape supply reel(20.1) and a tape take up reel(20.2), an apertured carrier tape(12) wound on the reels, the tape having sprocket holes and chip sites at which the chips are pre-loaded topside up, the tape allowing access to bath the topside and backside of the chips, a test station window(20.3) located in a surface of the cassette so as Provided is access to the topside of a chip in registration with the window, a first cavity(20.5) for receiving an indexing mechanism for moving the tape and for bringing chips sites into registration with the test station window and a second cavity(20.6) for receiving an ejector mechanism for pushing on the backside of a semiconductor chip.
