发明名称 FLEXIBLE PRINTED CIRCUIT BOARD
摘要 PURPOSE:To reduce the external size of an FPC by sandwiching a metallic foil circuit conductor between the bond layers of two insulating films, exposing one end thereof on both faces to make a connection end, exposing the other end on one face to make a soldered end, and making steps at the soldered end of each unit laminate. CONSTITUTION:A unit laminate 14 consists of a metallic foil circuit conductor 11 sandwiched between two insulating films 13A and 13B through bond layers 12, a connection end 11a exposed on both faces is formed at one end of the circuit conductor 11, and a soldered end 11b, for soldering to a drawn wire, exposed on one face is formed at the other end. In the same manner, a unit laminate 24 consists of a circuit conductor 21 sandwiched between two insulating films 23A and 23B through bond layers 22 and a connection end 21a and a soldered end 21b are formed at the circuit conductor 21. The unit laminate 24 is made longer than the unit laminate 14 so that the soldered end 21b may be exposed on the surface when they are piled and the connection ends 11a and 21a are arranged so as not to pile up.
