Abstract:
An interconnecting construction for interconnecting a flexible printed circuit and a wiring board, said flexible printed circuit comprising:a first circuit pattern formed on one face or two faces of an insulated flexible base film and a semiconductor device mounted at a predetermined region of said insulated flexible base film; and said wiring board comprising an insulated board on one face or two faces of which is formed a second circuit pattern for receiving a signal or transmitting it to said flexible printed circuit, wherein: said predetermined region of said insulated flexible base film is formed on such a side of said insulated flexible base film as to face said wiring board, constitutes said first circuit pattern, and is cut to form a notch so that at least one alignment portion used for alignment of said flexible printed circuit and said wiring board may be recognized visually therethrough; and based on a positional relationship between at least a part of an edge of said notch and said at least one alignment portion, making up said second circuit pattern, said flexible printed circuit and said wiring board are aligned with each other in at least two different directions therebetween.
