摘要： A member having metal is placed in a gas-impermeable container in a hermetically sealed condition together with a rust-proof agent packet, and is bonded to another metal by using a filler material and without using a flux.
It is desirable that a member having metal is placed and preserved in a gas-impermeable container in a hermetically sealed condition together with a rust-proof agent packet and an organic compound having carboxyl groups or aldehyde groups and having 4 to 10 carbons, and that the member having metal is bonded to another metal by using a filler material.
The method of the present invention prevents, in an extremely simple way and at a low cost, the oxidation of the metal surface by retaining the member including metal under a reductive atmosphere in which no oxygen, moisture or corrosive substances actually exist, and in which reductive gas coexists with the member having metal. Moreover, the method of the present invention enables easy and good bonding of the member having metal to another metal by using a filler material. Accordingly, it is unnecessary to give a flux cleaning treatment using organic halogen-based solvents after the solder bonding, the cleaning steps may be simplified, and cost reduction may be promoted.
