Filed: 1992-12-29
Abstract: PURPOSE:To obtain a circuit board capable of preventing soldered strength from lowering, by removing hydrogen in circuit conductors such as a copper layer, etc., by after-processing, formed by electroless plating. CONSTITUTION:After a board 2 on which a copper layer 16 is formed is cleansed with pure water, a protective film 18 is formed on the surface of the copper layer 16 by rustproof processing. And heat treatment, i.e., annealing of the copper layer 16 is performed. For example, the board 2 is put in a chamber, and its inside is caused to be an atmosphere not containing hydrogen or being under reduced pressure of hydrogen and not containing oxygen. And a heating source is driven, and a heating temperature is set. Hydrogen contained in the copper layer 16 is vaporized, emitted from the copper layer 16 into the chamber, and removed to the outside of the chamber. At this time, recrystallization processing in the copper layer 16 progresses simultaneously with the heat treatment, and crystal defects in the copper layer 16 are complemented by the recrystallization. Consequently, it becomes possible to make solder strength higher and obtain a circuit board having high-reliability circuit conductors.
