Abstract
PURPOSE:To arrange an internal element accurately and forcibly between an upper metal mold and a lower metal mold by a method wherein a protrusion is installed at one part of the upper metal mold and the lower metal mold and a tilt of the internal element is corrected. CONSTITUTION:Lead frames 3 are sandwiched between an upper metal mold 1 and a lower metal mold 2; at the same time, an element 4 is held by a protrusion 6 of the upper metal mold 1 and a protrusion 7 of the lower metal mold 2; a molding resin is filled into its surrounding space 5. If an external packaging operation by molding the resin is executed in this manner, the element 4 is corrected forcibly by the protrusions 6, 7 even when it is bent; the element 4 is not exposed to the outside. A hole 9 which has been made by the protrusion 6 of the upper metal mold 1 in an external packaging resin 8 is shaped; after that, a second resin 10 for sealing purpose is injected and hardened.
