  • “A thin double-sided copper-clad PCB sheet held on edge to show its consistent thickness and fiberglass core. Both sides are laminated with copper, making it suitable for CNC isolation routing, chemical etching, RF prototyping, and custom two-layer circuit board fabrication. A worn workbench is visible behind it.”
  • “A large double-sided copper-clad PCB blank resting on a workshop table with a soldering iron, pliers, and scattered components nearby. The board features copper on both sides, ideal for etching or CNC routing dual-layer circuits, PCB prototyping, and electronics fabrication.”

Double-sided PCB stock gives you room to build real boards — not just practice.

These FR-4 sheets use a fiberglass substrate with copper laminated on both faces. The dual layer allows traces to cross, signals to shield, and grounding to stay clean. It’s what makes two-layer boards the standard for everything from dev boards to embedded prototypes.

For CNC milling, keep feeds light and avoid deep passes, double-sided tape on the backside to keep things flat.. The goal is to isolate copper, not carve trenches. When etched, the uniform copper weight produces even line widths and consistent solder flow.
