## Description

This copper clad material is ideal for rapid prototyping of PCBs on a CNC machine. These particular units are single-sided, and measure 4 x 6 in. (101.6 x 152.4 mm) Because it is single-sided, the engravable copper is only present on one side. These units have 0.06 in. (1.6 mm) thickness. These items are best used with the [Nomad 883 Pro](https://core-electronics.com.au/search/?q=Nomad+883) 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 double-sided version of this product, please see: [TOL-14979](https://core-electronics.com.au/search/?q=14979)
