Photo (dry) film for circuit boards — precise, durable masking for PCB processing Key benefits Accurate patterning: transfers fine circuit details to the board for resolution traces and pads. Reliable hole protection: covers vias and throughholes effectively to prevent unwanted plating or etchthrough. Strong adhesion: bonds to nearly all board surfaces so the mask stays in place during electroplating, hole covering, and etching. Versatile process support: formulated specifically for electroplating, hole covering and etching operations used in PCB manufacture and . What it is and how it helps Product type: photosensitive dry film (also called photo film or dry film) designed for use on circuit boards. Function: apply the film to the board to create a thin, protective mask. The film enables delicate circuit features to be produced and protected during subsequent processing steps. Problem solved: prevents unwanted metal deposition or material removal in plated and etched areas, improves resolution of pattern transfer, and simplifies protection of holes and pads. Compatibility and performance Compatible with typical PCB processing workflows that require dryfilm masking for electroplating, hole covering and etching. Performance highlights: resolution for fine features and holecoverage capability, with adhesion strong enough for most board surfaces and common process conditions. Typical applications Smallbatch PCB prototyping: apply the film to protect areas during etching and achieve fine trace detail without investing in photolithography tooling. Selective electroplating: mask off pads and traces while plating contacts or edge connectors, ensuring clean, controlled plating only where needed. and rework: cover holes and sensitive areas during localized etching or plating to avoid damaging surrounding features. How to use (straightforward) Apply the dry film directly to the circuit board surface to form a protective mask for etching, electroplating, or hole covering operations. Key attributes (summary) Function: masking for PCB etching, electroplating, and hole covering Type: photosensitive dry film (photo film) Performance: resolution, hole coverage, strong adhesion Compatibility: adheres to almost all circuit board surfaces and supports standard PCB process steps This photo (dry) film provides a practical, reliable masking solution when you need precise circuit definition, dependable hole protection, and strong adhesion during electroplating and etching processes.
