Overview
The GC Electronics 22-338 is a pre-sensitized positive PCB blank board designed for custom circuit board fabrication. High-quality positive pre-sensitized PC boards are double protected from light and handling damage with a peel-off coating that protects the board while handling or cutting prior to exposure. This single-sided copper clad board is ideal for educational projects, prototyping, and hobbyist electronic applications where professional results matter.
