Microtrak FR4 Positive Photoresist Copper Clad Printed Circuit Board PCB - Rapid 03-5112, 203 x 114mm double-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.
