I have nearly completed making a UV LED lightbox to expose photosensitive PCBs. My intention is to
produce PCBs from pre-sensitised PCB (for PICAXE projects of course).
However whilst searching the Internet for possible suppliers of the PCBs I came across a number of sites on E***
that are selling "Photosensitive Dry FIlm Negative Photoresist, DuPont MM 540 sheets" in A4 size. Green in colour.
Also another site that has similar sheets but 6" x 8", Blue in colour. Possibly also made by DuPont as only difference appears
to be colour and size.
My Question is does anybody have experience of using this product? Is it worth buying? Ease of use? How good a result does it give?
I appreciate that a Negative transparency is required rather than a Positive transparency, not too difficult to produce.
I am asking because I still have a good stock of normal single sided PCB board that I previously used (either for Manhattan style building or
making PCBs using the Toner Transfer method) just sat there waiting to do something useful.
Many thanks clockwork
