Title: Electronic circuit part mounting board and production thereof
Inventor: MIYAGAWA NOBUYUKI
IPC: H01L23/12
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To prevent a dry film closing the opening for mounting an electronic circuit part from being peeled during a process for forming a plated circuit by covering the dry film with a protective layer. SOLUTION: A dry film 50 is applied to the entire surface of a board body 10 on the open side of an opening 40 thus closing the opening 40. The surface of the board body 10 including the upper surface of the dry film 50 is then coated entirely with a thermosetting resin liquid which is eventually set thermally to form a protective layer 60. Subsequently, a through hole circuit 70 is formed on the board body 10 by an ordinary plating method. Finally, the protective layer 60 is evaporated through irradiation with laser light and the dry film 50 closing the opening 40 is removed. Since the dry film 50 is not peeled in the process for forming the through hole circuit 70 by plating, adverse effects on the opening 50 or internal circuits 32, 34 can be eliminated.

Title: Hollow plastic package and manufacture thereof
Inventor: HASEGAWA TAKASHI
IPC: H01L23/04
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To expose all leads on the exposed surface of a hollow section by hanging down inner leads from the inner-lead contacting surface of a mold having projecting sections forming the hollow section and molding a resin, in a state where the inner leads reach the bottom of the mold on the side on which the hollow section is not formed. SOLUTION: A lead frame LF, which becomes a lead electrode, is sandwiched in advance between a male mold D1 and a female mold D2. The frame LF nearly vertically drops down toward a bottom face SB of the female mold D2 on the inside from a position corresponding to the lead contacting surface of the male mold D1. Consequently, the lead frame LF is not deformed by its own weight, mismatching between the male and female molds D1 and D2, etc., because the frame LF is maintained in a horizontal attitude at the position corresponding to the lead contacting surface of the male mold D1 by the front end of the drop-down section of the frame LF, which is in contact with the bottom face SB of the mold D2.  Therefore, a molten resin is not able to infiltrate between the lead frame LF and the lead contacting surface of the male mold D1, and accordingly, the occurrence of a nonconformity is eliminated where the resin is molded in a state with leads not being exposed in a hollow section.
