This copper clad material is ideal for rapid prototyping of PCBs on a CNC machine. These particular units are single-sided, and measure 4×6 in.（101.6×152.4 mm）Because it has copper on both sides, you can engrave these units on both the top, and the bottom. These units have 0.06 in.（1.6 mm）thickness. These items are best used with the Nomad 883 Pro using the free Carbide Copper app.
It's made of FR1 which uses laminated paper, instead of the more common FR4 that uses fiber glass fabric. This provides longer cutter life and eliminates the potential risk when milling boards that contain fiberglass to produce dust that can be harmful to your health; ain't nobody got time for that...
Note：If you'd like to purchase the single-sided version of this product, please see：TOL-14974
