Overview
The Kepro S2-710G is a photosensitized FR-4 copper clad laminate engineered for in-house circuit board manufacturing and rapid prototyping. Measuring 7×10 inches with a thickness of 0.062 inches, this dual-sided board features 1 oz copper on both surfaces and comes pre-coated with dry-film photoresist. Kepro’s photosensitized laminates are industry-standard blanks for hobbyists, prototypers, and small-batch PCB fabricators who need ready-to-etch stock without delay.
Key Features
- Photosensitized coating — pre-applied dry-film photoresist eliminates the need for manual resist application
- Dual-sided copper — 1 oz copper on both sides for two-layer circuit designs
- FR-4 substrate — flame-resistant, rigid fiberglass reinforcement for reliable mechanical and electrical properties
- Ready-to-use blank — no additional preparation; expose and etch immediately
- Compact size — 7″×10″ footprint fits most prototype and small-production batches
