Abstract:
The present disclosure discloses a method for wafer-level chip scale packaged wafer testing. The method comprises: dicing a wafer-level chip scale packaged wafer into a plurality of wafer strips each comprising a plurality of un-diced chip scale packaged devices; fixing the wafer strips onto a plurality of corresponding strip carriers respectively; testing the chip scale packaged devices of the wafer strips fixed onto the strip carriers by a testing equipment; and dicing the tested wafer strips into a plurality of individual chip scale packaged devices. Since the proposed method does not involve loading a multitude of diced chips into sockets one by one, but that a limited number of wafer strips are loaded onto corresponding strip carriers, flow jam is avoided.
