We offer 1/16", 1/32" and 1/64" FR4 laminate with 1 ounce copper per square foot. This flame retardant laminate is translucent in color and made of continuous woven glass cloth impregnated with epoxy resin. The copper on 1 ounce boards is 1.34 mil thick (0.0341 mm, 34.1 microns). The boards are made of FR4 which is a flame retardant version of G-10 material.
