Photosensitive (30cmx500cm/1ftx16.5ft) PCB Photosensitive Dry Film for Circuit Production Photoresist Sheets, Replace Thermal Transfer PCB Board

Etching: The dry film is resistant to most of the acid etching solution, the PH value can be resistant to most alkaline etching solution between PH8.0 ~8.5. Cover hole: 1.5 mil dry film can fully cover a 0.25 inches thickness hole. Plating: The dry film is available in most common use of the plating bath, no wrinkles, no color. Package include: 1x photosensitive dry film1x VANTIYAUS Paper protector BoxOperating Steps：1-Grinding CCL, this simple, using the finest polished clean water frosted paper on the line2-Removing film, photographic film is sandwiched between two layers of film, the first side can make use of transparent tape tear torn, try a few on the line3-And then foil, copper clad laminates can look a little cleaner, pasted, try not to have bubbles4-Good paste membrane used presses, not too hot, about 100 degrees from the fixing5The printed circuit board film, suggestion is to use film, the fine could reach the highest degree of accuracy if you did not ask for the paper to print it with sulfuric acid trip6The printed circuit on the photographic plate (Note: Dry film is negative, so to highlight the print, which we usually use photographic plate opposite) with ordinary energy-saving lamps 10 or so, if there

• Photographic film, also known as dry film, is used to make PCB board, stick it on top of the PCB, it will become a sensitive circuit board.
• Suitable for plating, hole covering，and the etching process.
• Excellent ability to cover holes,Excellent adhesion to almost all surfaces
• Front-panel is very clean after developed
• Parcel content:1*Photosensitive , 1*VANTIYAUS Box!!!
