RS PRO Tin Etching Chemical for Tin Plating

These crystals produce a bright plated finish PCB track and other copper alloys. The plating provides a highly solderable keying surface. Deposition rates of tin to tin of 1.5 to 2.0 microns in the first half hour and 3 to 4 microns in up to 2 hours can be achieved at an optimum room temperature. 5 litres of solution can be made by dissolving the crystals in water at 50°C, which is sufficient to cover 2.7m² of board. Instruction leaflet supplied.

Solid form

Suitable for use with the RS PCB tanks, these processing chemicals are supplied conveniently packaged to make up sufficient working solution for one tank ’fill’. Instructions for the use of these chemicals are printed on the package, and are repeated in the instruction leaflet supplied with all tanks in the range.

Always wear suitable protective gloves and faceshield when handling.
