203 x 114mm 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.


  • 203 x 114mm single-sided FR4 fibreglass laminate
  • Thickness 1.5mm
  • Copper thickness 35 micron
  • High resolution positive photo-resist
  • Supplied covered with blue light-proof film

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.

Cosmetically Rough

I ordered three of these boards recently. They all had multiple scratches on the plain (non-treated) sides. While these scratches do not affect electrical performance, they look ugly and detract from the final appearance of the project. There is no point in sending them back as other stock is probably the same and I can use them for prototyping. However, I do think Rapid should check their stock of this product to determine whether it meets minimum acceptable standards. Why cannot the manufacturer put a protective peel-off film on both sides of these boards?
