PRODUCTION OF INTEGRATED PRINTED CIRCUIT BOARD MOLDED FORM

摘要

PURPOSE:To produce a molded form which is little in warpage and accurate by setting the temperature of a male mold higher than the temperature of a female mold. CONSTITUTION:A prescribed circuit pattern 2 is formed on the face of one side of a printer circuit board 1 anal an adhesive layer 3 is formed on the face of the other side. The face of the circuit pattern of the printed circuit board 1 is fixed on the face of the male mold 5 of an injection molding machine and combined with a female mold 6 having an injection gate 7. An integrated printed circuit substrate molded form is produced by injecting molten resin from an injection gate 7 and integrating the printed circuit board 1 with a resin form 8 having a prescribed shape through the adhesive layer 3. In the case of producing the same, the temperature of the male mold 5 is set higher than the temperature of the female mold 6 and preferably set while keeping the temperature difference of 10-30 deg.C.
