UV Lamps for DIY Etching


Recommended Posts

The purpose would be for Photo etching. Like the Micro Mark photoetch kit, the instructions say to expose it outdoors. Living in the north east, the sunlight is unreliable. Using a UV light would be more reliable for light output and time of exposure.

Besides, grow light cost more that $15 when you add up the cost of lamps and fixtures.

For developing the photoresist I have built an UV light chamber using UV fluorescent tubes I bought at a local electronic supply store. But that cost me quite a bit more than $15. Before that I uses an antique sun-tanning lamp (from the '70s).

I used to use UV erasers for E-Proms and Micros when I was working. They were very expensive. Now retired, cost has to be low.

Still a 15W UV grow bulb and fixture is >$15 and does not concentrate the rays in a small area. DIY photoetching  normally is done on small projects. With the one shown you can expose a 6x6 area. I just ordered one for $13.96 with shipping.
