摘要： An insulating substrate with metal foils on both sides thereof is prepared, and a through hole that passes through the metal foils and insulating substrate is formed. An electroless copper plating layer is formed on an inner surface of the through hole and a surface of each of the metal foils, followed by the formation of an electrolytic copper plating layer on the overall surface of the electroless copper plating layer. After removing the electrolytic copper plating layer except the portions on the inner surface and a peripheral region of the through hole, the metal foils are processed to form conductor patterns.

摘要： A method of producing a multilayer wired circuit board that can suppress making gouge in an adhesive layer when a hole is formed by irradiation with a laser beam, to provide a smoothened inside surface of the hole so as to provide enhanced reliability of electrical connection. A first substrate 4 having the structure wherein a first metal foil 2 and a second metal foil 3 are formed on both sides of a first insulating layer 1 and a second substrate 7 having the structure wherein a third metal foil 6 is formed on a single side of a second insulating layer 5 are prepared, separately. Then, the first metal foil 2 of the first substrate 4 and the second insulating layer 5 of the second substrate 7 are bonded together through an adhesive layer 8. Thereafter, the resultant laminate is irradiated with a laser beam emitting from the first substrate 4 side toward the second substrate 7 side, to form a through hole 9. When the through hole 9 is formed, the adhesive layer 8 is irradiated with the laser beam decayed in energy after applied to the second metal foil 3 and the first metal foil 2. Hence, the adhesive layer can be prevented from being gouged by thermal decomposition, and as such can permit a smoothened inside surface of the through hole 9.

摘要： A resist film is formed on a conductor layer of a two-layered base material composed of a carrier layer and the conductor layer. Next, the resist film is exposed and developed, so that an etching resist pattern is formed. A region of the conductor layer that is exposed while not covered with the etching resist pattern is removed by etching. A conductor pattern is formed by removing the etching resist pattern. Then, an adhesive layer precursor is applied on an entire surface including an upper surface of the conductor pattern. The adhesive layer precursor is exposed and developed, so that an adhesive pattern is formed on the conductor pattern. After that, a base insulating layer is joined onto the conductor pattern with the adhesive pattern sandwiched therebetween. Finally, a carrier layer is separated from the conductor pattern, so that the FPC board is manufactured.
