Title: Method for molding module electronic part and molding apparatus therefor
Inventor: HIMENO YUJI
IPC: H01L21/56
Filed: 2001-08-27
Abstract: PROBLEM TO BE SOLVED: To prevent the formation of resin flash on the terminal part of a substrate at the time of injection of a sealant by injection molding and to also prevent the bending of the terminal part. SOLUTION: Before injection molding is started, a double-side adhesive pressure-sensitive adhesive sheet 15 is bonded to the surfaces of the terminal 2 and rib 5 formed on a substrate 3. By this constitution, the surface of the terminal 2 is closely bonded by the pressure-sensitive adhesive sheet 5 to prevent the inflow of a resin and resin flash is not formed on the surface of the terminal 2. Further, the pressure-sensitive adhesive sheet 15 prevents the downward bending of the substrate 3 at the part of the terminal 2 due to injection pressure by the double-side adhesiveness of the parts of the rib 5 and the terminal 2. That is, the position of the terminal 2 is fixed by the pressure-sensitive adhesive force of the pressure-sensitive adhesive sheet 15 without being affected by resin sealing pressure.  As a result, even if a receiving stand is not provided to the lower part of the substrate 3 at the part corresponding to the terminal 2, the bending of the substrate 3 can be prevented and no recessed part is left on the outer shape of a module electronic part after resin sealing.
