Rosin-free solder composition

摘要: A process for vapor phase soldering of electronic components comprises applying to the surface a substrate or on such solder cream comprising 85 90% finely divided metal and 10 15% fluorinated tertiary alkylamine, preferably perfluorotrihexyl amine, by weight sum two components, positioning substrate, with contacts cream-coated surface. The is placed in chamber contact boiling vapors second liquid alkylamine having lower point than cream, perfluorotriamyl chamber, melting fusing joints form substantially free organic residue. dissolves can be recovered from solution distillation reuse.
