The is a Prototype Board with FR4 epoxy glass laminate is dip coated in a high resolution positive working photo-resist. The photo-resist 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 photo-resist.
