Title: Lead frame for semiconductor chip
Inventor: MARUYAMA YUTAKA
IPC: H01L23/28
Filed: 1992-08-18
Abstract: PURPOSE:To prevent inclusion of bubbles in a molding resin for encapsulation by providing a hole for resin reservoir in the part opposed to the frame body which constitutes a gate for molten resin. CONSTITUTION:A resin reservoir 9 is provided. The location is in a frame body 2 portion in the longitudinal direction of a lead frame 1 and at a resin injection part 10 or a position opposed to a gate 12. Since the hole 9 for resin reservoir is formed, bubbles are also made to flow into the hole 9 for resin reservoir through an air vent portion located between a cavity and the frame body 2, along with molten resin injected from the resin injection port or gate 10. This allows the bubbles in the cavity to flow and, in addition, prevents the molten resin from flowing out of the lead frame 1, and the bubbles can be removed while preventing the formation of thick burrs.
