Three semiconductor testing procedures for QFN, DFN, CSP and WLP semiconductor packages use “test on tape“ process, with MCT Tapestry Film Frame Handler. Said to test multiple package types and sizes without requiring mechanical conversion kits. “Test after singulation” process reportedly eliminates semiconductor defects caused by mechanical sawing after electrical testing. The “wafer to pocket die traceability” system is said to track every unit from the wafer through test and inspection to the specific pocket on a reel of taped units; allows customers to perform virtual retest of taped devices in the event of a specification change or new OEM requirement.
