etching my first pcb's

@foTONICS Take heed of what Bob has said a fluorescent is better ... but will still take some time to expose correctly
BUT you really should be using a proper UV tube mounted in a suitable eye shielding box

@davenn Would I be ok to assume 15 to 20 minutes in the direct sun properly develops the photoresist? Assuming that the UV index is high, ie: 9+.

I suspect that the UV intensity would be a bit low ... would take a long time couldn't find anything definite online in a quick google search

Not trying to hijack this thread, but are the CFL lamps at 23 watts and higher with a color temp of 6400K sufficient enough to produce the necessary UV to develop?

I'm thinking a box lined with aluminum foil on the sides and top.

Looking good. Nice work for a first attempt. In fact, nice work period. Well done.
