    摘要: A leadframe enhancing molding compound bondability includes a chip base and a pin holder. The chip bases includes a chip pad and a support, wherein the chip pad includes a side protrusion extending out of the support, and the side protrusion has a lower surface, and the support has a sidewall, and wherein the lower surface and the sidewall interconnect at an intersection line, and the lower surface is formed upwardly with a recess. Further, a pin holder includes a pin stand and a seat, wherein the pin stand has an edge portion extending out of the seat, the edge portion has a lower surface, the seat has a sidewall, and the lower surface and the sidewall interconnect at a crossing line. The lower surface of the pin stand is formed upward with a recess. As such, the bondability between the leadframe and the molding compound can be greatly enhanced.
