TH98677B - Soldering process - Google Patents

Abstract

The process in which the molten solder is directly purified. In order to make The soldering process is more efficient and added that will provide better results. Especially For lead-free soldering Lead-free solder Will be used well because A good soldering temperature can be lower. The additive layer of action remains on the skin of the body. Molten solder To remove metal oxides from the solder And chasing metal oxides Into the layer of additive reaction liquid Will be an organic liquid containing Nucleophilic and / or electrophilic groups One example of it is a class of acid dimers that Fixed on the soldering machine By using waves that act to remove metal oxides from the body and Remove any debris or limes that may build up on the surface. Removing metal oxides will clean the tank and reduce the viscosity of the solder and the PC or similar pad it brings. Solder on the wave body There will be a connection point with a good working solder.
