How to make hobbyist photo resist




2003

It's hard for us to get a photoresist chemical to make a Print Circuit Board for soldering an electronic component.

Would you please tell us how to make a photoresist chemical that could be used for making PCBs.

Thank you very much.

The best source for this kind of information is usually expired patents. These days you will find the patents online from the US patent office and other sites. But you'll probably find that the chemicals you will need are harder to get than the commercial photoresist--so it's extra effort rather than saved effort. And this also assumes that production of photoresist is a simple matter of mixing whereas it may actually involve synthesis from precursors.
