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.
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.
Specification:
Dry Film Photoresist Size: approx. 30cm*500cm/0.98*16.4ft
Note:
Please allow 1-3mm differs due to manual measurement.

The product did not adhere to the copper board. Tried multiple ways and it did not work as it should have. Film easily came off even after exposure.

Do not buy this productThe film has been exposed to prolonged heat and is wrinkledI have done a couple of exposures and like a couple of other reviewers saw the bad results maybe a bit of experimentation you could get better results but why bother ?

Great resolution. Well packaged and shipped. Good quality - not dried out, which is a problem with older supplies.Highly recommended. Tested for photo etching of digital patterns via transparencies onto steel for metal rolling plates. Previously used to etch copper and silver. Easy processing with grocery shelf msterials.

Film is wrinkled, appeared to be stretched too tight when rolled. Would not lay flat even with heat and pressure. For a test I exposed and developed my image and that part was OK, but due to wrinkles film did not adhere and left lots and lots of hole and lines. Had to sand it off. Maybe the next roll will be OK // Second roll like the first. this is old stock. The cellophane tape sealing the ends of the wrapper is discolored yellowish from age. Upon opening; the tape (with arrow) holding the roll does not come off and must be cut or destroyed(old). This is a 3 ply film. The light blue photo resist between two clear layers. Most instructibles say that either identical layer can be removed to expose the photo resist NOT TRUE WITH THIS. One outer layer is soft and stretchy, other is hard, rigid, and crinkly. Must remove hard layer to apply photo resist to work piece. This leaves blue film with stretchy layer on top. This is the only way to have a chance to flatten out the wrinkles. I have made about 15 attempts to use this and only two were marginally acceptable. If you can buy flat sheets of photo resist or resist paint

I received a roll for PCB work and when I opened it I find that the whole roll (sheet on the roll) is full of creases from where it's been spooled on. This is not just the covering but the actual film, which means you can't get a flat film onto your project no matter what you do (I've tried water, laminating etc). Nothing works.[update] I ordered a replacement through Amazon. The replacement roll has exactly the same problem. I suspect the sell has stored this in their garage which gets hot in the summer and has caused their whole stock to get spoiled. The creases look like they are heat-cool cycle creases. Maybe it's an age thing. I bought some film directly from China and it is perfectly flat and uniform as it should be.BOTTOM LINE: Do not buy from this vendor again. They are shipping bad quality/defective product.
