Method for soldering, fusing or brazing

摘要: .[.Article.]. .Iadd.An article .Iaddend.to be soldered, fused or brazed is placed in hot saturated vapors generated by continuously boiling .Iadd.a .Iaddend.heat transfer liquid having selected properties including .Iaddend.boiling point at least equal to, and preferably above, .Iadd.the .Iaddend.temperature required for .Iadd.such .Iaddend.operation. Vapors condense on .Iaddend.article give up latent heat of vaporization to soldering, fusing brazing. .[.Heat.]. .Iadd.The .Iaddend.transfer may a fluorocarbon. Apparatus shown brazing single article, batch articles, moving line articles. Specifically, mass reflow soldering wave operations are described. .Iadd.
