High quality single sided board 220 x 100mm. Coated with positive working photo-resist. The glass fibre laminate is to BS4584 and MILSPEC MIL-P-13949GE GRN. The photo-resist is applied by a roller coating process which ensures a particular even layer to a thickness of 5 microns. The photo-resist is then high temperature cured which, combined with its tough plastic film covering, results in a durable board which can be handled, guillotined and processed with a high degree of safety.
