METHOD OF REDUCING VOIDS IN ENCAPSULANT

摘要

A method of reducing voids within a bead of encapsulant material deposited on a series of wire bonds connecting a micro-electronic device with die contact pads extending along one edge, and a plurality of conductors on a support structure such that the wire bonds extend across a gap defined between the edge of the micro-electronic device and the plurality of conductors. The method has the steps of depositing at least one transverse bead of encapsulant in the gap extending at an angle to the edge of the micro-electronic device, and, depositing at least one longitudinal bead of encapsulant in the gap extending parallel to the edge of the micro-electronic device.
