A manufacturing process for a Quad Flat Non-leaded (QFN) chip package structure is provided. First, a patterned conductive layer and a patterned solder resist layer on the patterned conductive layer are provided. A plurality of chips are bonded onto the patterned solder resist layer such that the patterned solder resist layer are between the chips and the patterned conductive layer. The chips areelectrically connected to the patterned conductive layer by a plurality of bonding wires, wherein the chips and the bonding wires are at the same side of the patterned conductive layer. At least one molding compound is formed to encapsulate the patterned conductive layer, the patterned solder resist layer, the chips and the bonding wires. Then, the molding compound, the patterned conductive layerand the patterned solder resist layer are separated.
