Hello,First off, thank you to every one of you for answering the other thread.It's given me plenty to research and perhaps over analyse.I think I'm going to go for the ready kit put together by Rapid, this iswritten up below. But before I do that I'm left wondering something..Where I have my nails done they use one of the little UV boxes. They'rehere on eBay;Now what I'm wondering is. Would one of those do the job? Or more to thepoint, would it be cost effective to strip one down and use the parts.Thereafter ALL you need is an enclosure and some perspex. Also today it'sbecome clear regarding 4mm glass that suppliers either only stockUV-blocking glass, or don't even know at all. No one knows what they'reselling anymore or even cares!! This is the UK, it's a dump full of underachievers and everyone has a degree in Travel & Tourism or Marketing,everyone else is on state benefits.So.. The nail box up above? :-)Warm thanks,AlisonThe following will need to be viewed in a fixed font such as Courier to allline up;"Sourcing a UV Exposure Box for PCB Development.-----------------------------------------------0.

When considering building one the light outputhas to be in the range of 400nM. There is absolutely no point inapproaching DIY outlets as they have haven't a clue what you're talkingabout (I've been out hunting today). Blacklight dark...

Not sure where you get your figures from, or if you see how they are split down and attributed to what - as i say, most funding doesnt go to the undergrad students.

Totally agree, and yes a slight humour bypass - I tend to get defensive when people attack the institutions I work for and have spent the last 8 years doing 80 hour weeks to progress in, its only natural. And yes, we too skit the mickey mouse degrees. Just be wary of tarring all "students" with the same brush thats all :)

What do you use to sensitize the board? Or do you buy presensitized?

Hi Leon,

Noted. In the end I bought the one on eBay. But still have an idea about an LED UV box for the small size.

Aly :-)
