发明名称 MANUFACTURING PROCESS FOR A QUAD FLAT NON-LEADED CHIP PACKAGE STRUCTURE
摘要 A manufacturing process for a Quad Flat Non-leaded (QFN) chip package structure is provided. First, a conductive layer having a plurality of recesses and a patterned solder resist layer on the conductive layer are provided, wherein the patterned solder resist layer covers the recesses of the conductive layer. A plurality of chips are bonded onto the patterned solder resist layer such that the patterned solder resist layer is between the chips and the conductive layer. The chips are electrically connected to the conductive layer by a plurality of bonding wires. At least one molding compound is formed to encapsulate the conductive layer, the patterned solder resist layer, the chips and the bonding wires. A part of the conductive layer exposed by the patterned solder resist layer is removed so as to form a patterned conductive layer. Then, the molding compound and the patterned conductive layer are separated.
