Description:

- 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.
- ability to cover holes
- High Resolution
- adhesion to almost all
- Image after exposure
- is very clean after developed

Specification:

How to use it :

- 1. Clean your board. film a little larger than your board.
- 2. Apply Resist: This Photoresist has , the top and bottom layers are , so at the first, you need remove layer, the easy way is to use two small pieces of tape. Then apply the middle layer on board.
- 3. Expose: Place your negative artwork over the rest layer.
- 4. Develop: Remember: you need NEGATIVE film developer, Remove the rest layer on the film. After 3 minutes take board out of developer and hold under running water to check,you can always place it back in the developer .

Etching:

- The dry film is resistant to most of the 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 , no color.

Package Includes:

1 roll photosensitive dry film
