Abstract:
1. A method for manufacturing circuit devices, the method comprising: forming conductive patterns on a planar body, wherein the planar body is a conductive foil and the conductive patterns are formed in a convex shape by separation grooves, the conductive patterns forming mounting portions for circuit elements; disposing a circuit element on at least one of the mounting portions; bringing a backface of the planar body into contact with a lower mold having air vents to define a resin injection cavity above the planar body and air release passages that extend beneath the planar body, wherein the air release passages are at least partially formed from the backface of the planar body and the air vents; sealing a surface of the planar body with an insulating resin so that the circuit element is covered therewith; and separating each mounting portion.
