ROSIN-FREE, LOW VOC, NO-CLEAN SOLDERING FLUX AND METHOD USING THE SAME |
摘要 |
A rosin-free, low VOC, no-clean soldering flux consists essentially of one or more halide-free carboxylic acid activators in an aggregate amount not exceeding about 8 % by weight of the flux; one or more alkyl amines capable of forming amine salt of the one or more activators and in an aggregate amount not exceeding about 10 % by weight of the flux; and water, with or without a surfactant. The flux is particularly useful in a method of producing soldered printed wiring assemblies with minimal residual ionic contamination, so that post-soldering cleaning of the assemblies is unnecessary.
