[Also in Division C7F] A process for batch production of nickel phosphorus film resistors (having a small temperature coefficient of resistance, i.e. within Œ 50 parts per million) consists in depositing nickel phosphorus films by electroless plating on insulating substrates such as plates or rods of glass, porcelain, steatites, synthetic resins &c. The process uses an aqueous solution with 0 to 0À09 g. moles/lit. of EDTA or one of its salts (EDTA : ethylene diamine tetra-acetic acid) and comprising a hypophosphite, a nickel salt, a pyrophosphate and an orthophosphate, the amount of these constituents being sufficient to give on complete dissociation into ions, 0À15 to 0À3 g. ions/lit. of hypophosphite, 0-01 to 0À1 g. ions/lit. of nickel, a pyrophosphate concentration between 5 and 15 times the difference between the concentration of metal and EDTA or its salts, an orthophosphate concentration of 0À01 to 0À06 g. ions/lit. with the proviso that any EDTA or its salt present should be at least 0À005 g. mols/lit. less than the ionic concentration of nickel in g. ions/lit. and the further proviso that amounts of the constituents in the bath must be such that the pH value of the solution remains within the range 5-7. Several examples of methods and solutions used for coating batches of substrate rods are given. Films so deposited are washed, rinsed in distilled water and finally in acetone, dried at room temperature and finally stabilized by heating them at 250‹ C. Stabilized resistors may be finished by trimming to the required value and fitted with terminals, and may finally be coated with an organic protective coating such as of a stovable lacquer or a thermoplastics. The EDTA content in the solution may altogether be absent if the other materials in the solution are present in their pure form.
