Description
Product selling points:
-Photographic film, also known as dry film, is used to manufacture PCB boards. When attached to the top of the PCB, it becomes a sensitive circuit board.
-Suitable for electroplating, hole covering, and etching processes.
-Excellent ability to cover holes
-High resolution
-Excellent adhesion to almost all surfaces
-Image clarity after exposure
-The front panel is very clean after development

Product parameters:
Dimensions: 15 x 200 cm/5.91 inches x 78.74 inches
Color: Blue

How to use it:
1. Clean your board. Cut dry movies that are slightly larger than your circuit board.
2. Application of anti-corrosion agent: This type of anti-corrosion agent has three layers, with the top and bottom layers being transparent protective layers. Therefore, the first step is to remove one layer of protective layer, and the simplest method is to use two pieces of transparent tape. Then apply the middle layer on the ship.
3. Exposure: Place your negative artwork on other protective layers.
4. Development: Remember: You need a negative developer to remove the remaining protective layer from the film. After 3 minutes, take out the development board and place it in the running stream for inspection. If more time is needed, you can put it back at the developer’s place.
etching
This dry film is resistant to most acid etching solutions and has a pH value that can resist most alkaline etching solutions between pH 8.0 and 8.5.
Cover hole
1.5 mils of dry film can completely cover holes 0.25 inches thick.
electroplating
The most common use of dry film for electroplating baths is wrinkle free and colorless.
Package includes
1 roll of photosensitive dry film
