Subject: RE: [Homebrew_PCBs] UV Light Sources

From: "John Craddock" <John.Craddock@...>

I read somewhere on the web that a mercury vapour lamp with the outer uv blocking envelope removed gives a very good source of uv light for photo-pcb resist curing. Obviously removing the outer envelope would require that the uv exposure box be totally enclosed when the system is operating. Can any one confirm that this is comparable or better than the black-light fluorescent approach?
TIA
