While wandering through EBay looking for PCB related stuff I came across this listing :-

http://cgi.ebay.co.uk/UV-Lamp-Light-Dryer-CND-NAIL-Gel-polish-Nail-Curing-/280658859856?_trksid=p5197.m263&_trkparms=algo%3DSIC%26itu%3DUCI%252BIA%252BUA%252BFICS%252BUFI%252BDDSIC%26otn%3D10%26pmod%3D280683232592%252B310325092023%252B140563846606%26po%3DLVI%26ps%3D63%26clkid%3D642812078115852543#ht_4993wt_731

Essentially it is a UV Lamp for drying those lovely plastic nails that women wear. I wonder if anyone here has tried one (the Lamp, not the nails) for exposing photosensitive PCBs. It looks like an inexpensive solution compared with a DIY lightbox...

Should work, that wavelength would be UVA. Nice little unit for small PCBs.

The glue/gel they use is UV sensitive, it doesn't set until exposed to
light, and then it sets really fast. Natural light works, but the UV lamp
is faster. It's similar to superglue without the quick setting bit. Some
guitar players get false nails, so you occasionally see blokes in the
salons.

If you ever need to glue glass that's the stuff to get.

They use the same sort of stuff in those 3D printers where it sets when the
laser hits it.

Here is my homemade unit:

It works very well and was cheap to make.

Please tell me more details. I would like to give this method a test. I know there is a wealth of information with Google but imitating yours would likely save both time & money!

I bought a couple of standard 12" fluorescent units, disassembled them,
and substituted UV tubes for the standard ones.

The box was made from MDF and square wood strip, glued and screwed
together. I had a sheet of ordinary window glass cut to size, which
rests on the upper wood strips.

I use an exposure time of 11 minutes for positive resist pre-coated
board material, timed with a kitchen timer app on my Dell Streak. I
could make a timer to switch it on and off, but it isn't worth the effort.

I get 8/8 mil tracks and can do TQFP parts with 0.5 mm lead spacing
without any problems, with transparencies produced on my cheap HP 5940
inkjet printer.

Here's mine. Works well, not as cheap, probably overkill, but if you
know me you'll understand ;-)

Very cool. Do you have design info (schematics, pcb's) for what appears to be solid state ballasts shown in the pictures?

Hi:



They are salvaged from energy saver lights from 1 dollar-shops, you only
need to buy the appropriated wattage ones. J

Same thing as the original post, but 9w as opposed to 36w. No timer either,
not that it would've been much use as-is anyway. Much cheaper though.
