The Mega Electronics FR4, the double-sided photoresist PCB board is a new age device with 305mm length, 457mm width and 1.6mm thickness. This Microtrak epoxy glass laminate is a dip-coated with a high-resolution positive-working photoresist. It contains a dye that gives a good contrast against the copper, allowing boards to be easily inspected at the developing stage. This pane is protected by a specially designed lightproof blue film that allows panels to be guillotined without the risk of fracturing the photoresist. It is applicable for producing and prototyping printed circuit boards PCBs.

• Base material is epoxy glass fabric laminate
• Copper thickness is 35μm
• Number of sides is 2
