Abstract
Flux compsn. comprises a liq. or solid flux, e.g. tartaric acid/sarcosine, oleic acid/sarcosine or 11-amino undecanoic acid, dispersed as an emulsion or a suspension in a liquid, e.g. isopropyl alcohol opt. mixed with water, in which the flux is insol. Tinning of a printed circuit board involved applying the dispersion (pref. as an unstable foam) to the p.c.b., applying a molten solder compsn. to the fluxed board, and opt. washing the board in a liquid in which the flux is soluble. The dispersion may be produced by micronising a solid flux e.g. in a fine grinding mill and dispersing the material in a liquid or by dispersing liquid or solid flux in a liquid using a liquid flow mill. The dispersed particles pref. have a dia. of less than 120 microns. The dispersion may be applied to a p.c.b. by brushing, spraying, dip coating, or pref. for continuous prodn. processes, foam coating (a small amt. of wetting agent being added).
