03-5144-1, Single-Sided Copper Clad Board FR4 With 35μm Copper Thick, 233.4 x 160 x 1.6mm

Microtrak FR4 epoxy glass laminates are dip coated with a high resolution positive working Photoresist. The Photoresist contains a dye which gives a good contrast against the copper, allowing boards to be easily inspected at the developing stage. Panels are protected by a specially designed light-proof blue film which allows panels to be guillotined without the risk of fracturing the Photoresist.
