Feature

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 coveringand the etching process.
Excellent ability to cover holes,Excellent adhesion to almost all surfaces
Front-panel is very clean after developed

Operating Steps

1-Grinding CCL, this simple, using the finest polished clean water frosted paper on the line

2-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 line

3-And then foil, copper clad laminates can look a little cleaner, pasted, try not to have bubbles

4-Good paste membrane used presses, not too hot, about 100 degrees from the fixing

5The 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 trip

6The 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

Note:

Order from VANITYAUS it's 100% original ,but ordered from others could be fake one and without security.
