  • Patent number: 6979598
    Abstract: The present invention is directed to a method of attaching a leadframe to a singulated good die using a wet film adhesive applied in a predetermined pattern on the active surface of the good die, the lead finger of a leadframe, or both. By applying the adhesive only to identified good dice, time and material are saved over a process that applies adhesive to the entire wafer. By attaching the leadframe to the good die with a wet film, it is possible to remove the leadframe from the good die for rework if the good die subsequently tests unacceptable.
