Velleman PFD2 fotogecoate PCB-basismateriaal 270 x 115 mm enkelzijdig fenol

The Velleman PFD2 is a photo-coated base material for PCB prototyping, offering a single-sided copper-clad phenolic board with a positive-acting photoresist layer. Unlike standard blank copper boards, this pre-sensitized surface allows direct UV exposure of circuit patterns, eliminating the need for manual resist application.

Highlights

• Pre-coated with positive photoresist for direct UV exposure
• Single-sided copper cladding with 35 µm copper thickness
• Phenolic (FR2) base, 1.5 mm thick, for easy drilling and cutting
• Board size: 270 mm × 115 mm, suitable for multiple small circuits
• Compatible with common developers and etchants

In daily use

Expose the board through a printed transparency or photomask using a UV source (365–405 nm), develop with a sodium hydroxide solution, then etch with ferric chloride or ammonium persulfate. The positive photoresist yields sharp traces for reliable DIY PCB fabrication.
