The GC ELECTRONICS 21-330 is a bare copper circuit board designed for a wide range of electronic applications. Constructed with one ounce (0.0014") of copper on a base of either FR-4 (G-10) fiberglass or CEM-1 type epoxy reinforced board, this board offers a robust and reliable platform for circuit design and fabrication. Its 1/16" thickness provides structural integrity while maintaining compatibility with standard manufacturing processes. This board is a cost-effective solution for prototyping and production runs.
