Cheapo DIY UV Exposure Unit for PCBs

[Yorkie]

Sorry Alan - I didn't want to imply that all that all that is needed to make a UV exposure unit is a tube and starter. A ballast and lamp-holders etc for the tubes would be needed, and I dare say that Rapid sell those too. I simply wanted to point out where UV tubes of the correct wavelength can be found at a reasonable price for anyone wanting to go down that route. There have been several excellent designs with varying degrees of sophistication in magazines such as EPE in recent years, using such tubes, but I think that were I starting out now, I'd give the UV LED design a whirl.
