Fluxes removing

Soldered joints present their own characteristic corrosion problems usually in the form of dissimilar metal attack often aided by inadequate flux removal after soldering. Such joints have always been a source of concern to the electrical industry. Lead-containing solders must be used with caution for some types of electrical connection since PbfOHjj.PbCOj may be found as a corrosion product and can interrupt current flow. Indium has been found to be a useful addition to Sn-Pb solders to improve their corrosion resistanceHowever, in view of the toxicity of lead and its alloys, the use of lead solders, particularly in contact with potable waters and foodstuff s, is likely to decline.

C12-0091. To make a good solder joint, the liquid metal solder must adhere well to the metal surfaces being joined. Flux is used to clean the metal surfaces. What types of substances must flux remove ... [Pg.885]

Excess flux will not compromise joint quality and provide for flux removal, since residues will be less loaded with metal oxide and more soluble in water. [Pg.61]
