1 Roll Photosensitive Dry Film PCB Photoresist Film for Circuit Production Photoresist Sheets 30cmx1m

Specification: Brand new Type: photosensitive dry film Color: as picture shows Size: approx. 30*100cm / 11.81'' x 39.37'' Quantity: 1 roll PCB photosensitive dry film for circuit production Features: 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 High Resolution Excellent adhesion to almost all surfaces Image clarity after exposure Front-panel is very clean after developed How to use it: Clean your board. Cut dry film a little larger than your board. Apply Resist: This Photoresist has 3 layers, the top and bottom layers are clear protective layer, so at the first, you need remove one protective layer, the easy way is to use two small pieces of scotch tape. Then apply the middle layer on board. Expose: Place your negative artwork over the rest protective layer.
