160 x 100mm single-sided copper-clad fibreglass PCB laminate photo-etch board coated with a high resolution photo-resist.
Microtrak laminates consist of FR4 epoxy-glass laminate sheets, dip-coated with a positive working photo-resist. The photo-resist contains a dye that provides a good contrast against the copper and allows boards to be easily inspected at the developing stage. Boards are protected by a specially designed light-proof blue film which allows them to be guillotined without the risk of fracturing the photo-resist.
Microtrack FR4 boards require a developer strength of 10 to 1. (Not 20 to 1 as with other products it replaces.)
Exposure time is typically 2.5 to 3.5 minutes.

A. Hi Jonathan, thank you for your question. Exposure time is typically 2.5 to 3.5 minutes.
it would appear the instructions for developing the board are incorrect it should be 10 .1 100ml in 900 ml however the processing instructions state 80 ml in 920 ml . A phone call to rapid confirmed that this instruction is incorrect.
Good quality board which produces excellent results.
