Have a look at Circuit Specialists' selection of inexpensive copper-clad board material with thicknesses of 1/16" or 1/32" in sizes from 3"x5" up to 12"x12". We have both single- and double-sided copper-clad boards featuring one ounce copper and FR-4 fiberglass or CEM-1 epoxy reinforcement. Developed specifically for circuit processing industry applications, the FR-4 reinforcement is made of continuous woven glass impregnated with epoxy resin, making the translucent laminate flame retardant.

Our pre-sensitized positive photoresist printed circuit boards are ideal for prototyping, student training, and small production runs. These PCBs provide high resolution and excellent fine-line control. The high-sensitivity positive resist coated on one ounce copper foil allows you to go directly from your computer plot or artwork layout to the board — no need to reverse art. Click here to go to MG Chemicals "Instructions for the Basic Positive Prototyping Process."
