Abstract
Abstract A molded circuit board is constructed by forming a plurality of resin moldings integrally with a circuit film including an insulating film and circuit pattern on the insulating film, spaced specified distances therebetween, on one side of the circuit film. The plurality of moldings can be assembled into an electronic device box by bending the intermediate portion, between the moldings, of the circuit film.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
97 words
A molded circuit board comprising: a circuit film having a desired circuit pattern formed thereon; and a plurality of resin moldings formed on one side of said circuit film, said resin moldings being molded and spaced at specified distances from adjacent moldings so as to be integrated with and formed in one molding operation with said circuit film, said plurality of resin moldings thus forming at least one molding-free portion being capable of being assembled into a box with only said at least one molding-free portion of said circuit film being bent during assembly into a box.
Claim 2
Dependent Claim
97 words
A molded circuit board comprising: a circuit film having a desired circuit pattern formed thereon; and a plurality of resin moldings formed on one side of said circuit film, said resin moldings being molded and spaced at specified distances from adjacent moldings so as to be integrated with and formed in one molding operation with said circuit film, said plurality of resin moldings thus forming at least one molding-free portion being capable of being assembled into a box with only said at least one molding-free portion of said circuit film being bent during assembly into a box.
Claim 3
Dependent Claim
36 words
A molded circuit board according to claim 1, wherein said at least one molding-free portion of said circuit film has a length so as to slacken when said resin moldings are assembled into a single body.
Claim 4
Dependent Claim
33 words
A molded circuit board according to claim 1, wherein said plurality of resin moldings are assembled into a polygon box, said moldings constituting faces of the polygon box, when said moldings are assembled.
Claim 5
Dependent Claim
32 words
A molded circuit board according to claim 1, wherein the circuit pattern formed on a molding-free portion of said circuit film is wider than that of the remainder of said circuit film.
