Title: Method for producing circuit board
Inventor: MUTO MASAHIDE
IPC: H05K3/06
Filed: 2002-07-30
Abstract: <P>PROBLEM TO BE SOLVED: To increase the yield greatly by preventing short-circuiting to a non-circuit part through a plating layer.  <P>SOLUTION: The boundary part between the circuit part 21 and the non-circuit part 22 of a thin-metal film 2 formed on the surface of an insulation base material 1 is irradiated with an electromagnetic waves, e.g. a laser, and removed. Subsequently, the circuit part 21 of the thin-metal film 2 is subjected to plating and the non-circuit part 22 is removed by etching thus forming a circuit pattern. Plating thinner than a required thickness on the circuit part 21 of the thin-metal film 2 and etching for removing the thin-metal film from the non-circuit part are repeated, in this order. Since the non-circuit part 22 of the thin-metal film is removed by etching under a state subjected to thin plating, plating does not short-circuit to the non-circuit part 22 of the thin-metal film, when plating is effected up to a required thickness.  <P>COPYRIGHT: (C)2004,JPO
