Fortex Microtrak FR4 Positive Photoresist Copper Clad Printed Circuit Board PCB

Fortex Brand: Fortex

Single-sided and double-sided copper-clad fibreglass PCB laminate photo etch boards 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.

  • FR4 fibreglass laminate
  • Thickness 1.5mm
  • Copper thickness 35 micron
  • High resolution positive photo-resist
  • Supplied covered with blue light-proof film
  • Single or double sided
  • Wide range of sizes

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.
