Mega Electronics Photoresist PCB Board 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. Features and Benefits • Base material is epoxy glass fabric laminate
• Copper thickness is 35μm
• Number of sides is 2
