Double-sided PCB Boards | FR-4 Fiberglass, CNC Milling Stock (100x150x1.5mm)
In stock: 1-3 business days
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.
