ITEM NAME:30cm x 5M Photosensitive Dry Film For PCB Circuit Production Photoresist Sh U7B4 30cm x 5M Photosensitive Dry Film For PCB Circuit Production Photoresist Sh U7B4 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 adhesion to almost all surfaces Image clarity after exposure Front-panel is very clean after developed 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. Material: Resin colour: Blue size: 30cm x 5M Package include 1x photosensitive dry film/in a pack Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
