Hey! I'm looking at doing some single sided
pcb's. From what I can tell,
if
I want the pre-sensitized board to expose in a reasonable amount of time,
I
am going to need to make a UV box to expose it with. I could apparently
use
a regular fluorescent bulb but it will take 30-50 minutes to be ready for
developing.... And with cats, dogs and teenagers (and a friends 3 year
old
many days) that is way too long to assume something is going to be left
without being bumped or knocked over :)
So, anyone have a good source for UV bulbs between 350 and 440 nm ? At a
reasonable price?
Using old scanners as lightboxes is an old trick :) And it keeps your
board and drawing aligned :)
