发明名称	MANUFACTURE OF CIRCUIT BOARD FOR WATCH
摘要	PURPOSE:To contrive the improvement in the reliability of a circuit board for a watch by forming a projection on a mold for molding the circuit board to thereby allow the projection to hold the wiring pattern surface of an IC, sealing the IC, and thereby preventing the shortcircuit of the peripheral portion of the IC. CONSTITUTION:A flexible board 3 is inserted into a mold 17, the bonding portions 18 of the wires of the IC2 on the board 3 are supported by the projection 19 of the mold 17, and lead wires 16 are supported by the oblique surfaces 19 of the projection 19. When the resin is flowed in a direction as designated by arrows, the IC2 and the lead wires are urged to the projection 19 of the mold 17 to be formed. Accordingly, the lead wires 16 may not be bent, nor be brought into contact with the peripheral edge of the IC, and its reliability can be consequently improved.
