Abstract
1324418 Solder flux EI DU PONT DE NEMOURS & CO 26 Aug 1970 [26 Aug 1969 28 Nov 1969 28 May 1970] 41140/70 Heading C7M [Also in Division B3] A solder composition comprises a solder metal dispersed in a liquid containing by weight (a) 0À01-75% of at least one of hydroxyl substituted aliphatic or mono nuclear aromatic or polynuclear heterocyclic amines with the hydroxyl and nitrogen in a vicinal relationship, (b) 1-75% rosin or a derivative, (c) 0-75% organic solvent and (d) 0-20% thixotropic agent. The weight ratio of solder to liquid is preferably 1:20 to 20:1 with liquid preferably containing 1-10% (a) 30-60% (b), 40-60% (c) and 0À5-10% (d). Component (a) may be di or triethanolamine, 8-hydroxyquinoline, 2- (2-aminoethylamine)- ethanol, diglycolamine, α hydroxymethyl pyradine and N- hydroxyethyl ethylene diamine. Component (c) may be acetone, benzene, toluene, aliphatic alcohol, mineral spirits,, CCl 4 , a terpene, ethylene glycol, glycerol methyl ethyl ketone or mixtures of these. The solder metal is – 100 mesh and may contain Au, Ag, Sn, Ge, Sb, Bi, Pb, In, Ga, Zn, Cu, Si, P. The composition can be screen printed on to a conductor pad on an Al 2 O 3 substrate and heated to fusion on an inert or reducing atmosphere.
