Dry Film Photoresist is the modern reliable and easy way of doing home-brew Printed Circuits using Photolithography!
* No laminator needed for smaller boards up to about 7cm x 10cm!
* No darkroom needed - work under normal household lighting!
* No UV lights needed - as long as it's sunny!
* Full instructions - 283.mytrademe.info - updated occasionally, check for latest!
This is a big pack of 10 convenient sheets of 12x17, easily cut to your size (note that you WILL need some overlap to successfully adhere it, at least 5mm all around).
See the PDF document above for full instructions.
With dry film, you apply a piece of film to a clean PCB, expose to a negative artwork printed on tracing paper, drop it in a solution of Washing Soda (Sodium Carbonate) which you can buy from the supermarket for a few minutes, wipe off the unexposed resist, and etch.
This allows a repeatable, convenient, and cheap means of doing high-quality printed circuits with fine traces.
In comparison to the toner transfer method, the repeatability and less chance for messing it up, is the key. It also sounds cooler that you are doing "photolithography" and "chemistry", rather than some ironing.
Please note that the unexposed film may appear either a greenish-turquoise, or a slightly darker blue (basically different manufacturers, it works the same for our hobby purposes, just depends which one the supplier had in stock when I import a batch), you will be sent all the same type for your order, but if you are a return customer you may get the "other" one, do not be concerned it will work just fine ) If you are by some chance looking for a specific "version" feel free to ask a question first to see which one I have in stock currently.
