Abstract

1,050,441. Soldering. M. OHARA. May 15, 1963, No. 19282/63. Heading B3R. [Also in Division C7] A fluxed solder is formed by extruding a powder mixture of a minimum of 75% by weight of two or more of the metals Sn, Pb, Bi, Cd, In, Cu, Hg, Zn, Ni or Ag and a maximum of 25% by weight of a flux. The extrusion conditions are: 6000-10,000 Kg./cm.<SP>2</SP> at 18-40‹C., or 8000-15,000 Kg./cm.<SP>2</SP> at 90- 160‹ C. or 2500-6000 Kg./cm.<SP>2</SP> at 3-18‹C. The fluxes may be chlorides of NH 4 , Zn, Sn; bromides of NH 4 ; the fluoride or acid fluoride of NH 4 ; stearic acid, lactic acid, glutamic acid, salicylic acid phenyl bromide, dimethylamine hydrochloride, aniline hydrochloride, cetyl pyridium hydrochloride, rosin, dioctyl phthalate, dioctyl adipate. Many examples of different soldering alloys are given and the solder may be in the form of wire, rod, sheet, flat, bar, angle or tape.
