Screen Defined, Thermal Curing, Liquid Plating Resists
Plating is the most complex process associated with circuit production by screen printing. The formulation of a plating resist is critical; it must withstand long periods of plating in either acid or alkaline baths and the various pre-cleaning processes. Plating resists must not contaminate plating baths and afterwards must be readily removable in either organic solvents or aqueous solutions. They must also be capable of very fine print definition.

All the plating resists below can be used as etch resists if required.

The products below are. capable of producing circuit patterns with tracks and gaps of between 200 – 250micron. (8 - 10 mil.). The Coates range of plating resists is suitable for use with most commercially available electroplating solutions including acid copper, pyrophosphate copper, tin lead fluroborate, nickel, bright tin, acid gold, neutral gold and alkaline gold. Coates currently offer a combination of two products both available in two different colour versions.
