发明名称 Transfer mold semiconductor packaging processes
摘要 In one implementation, a circuit substrate includes a substrate having opposing sides. At least one of the sides is configured for transfer mold packaging and has conductive traces formed thereon. A soldermask is received on the one side, and has a plurality of openings formed therethrough to locations on the conductive traces. The soldermask includes a peripheral elongated trench therein positioned on the one side to align with at least a portion of an elongated mold void perimeter of a transfer mold to be used for transfer mold packaging of the one side. In one implementation, the invention includes a transfer mold semiconductor packaging process. In one implementation, the invention includes a semiconductor package. In one implementation, the invention includes a ball grid array.
