[alt-photo] Re: UV Processing units

[Ian Hooper]

A few years ago, I looked at the options of cooking PCB's with UV Leds, the
only leds I could source seemed to be high cost / low output, or from
'questionable' sources. That was some time ago, so imagine there are new
products available on the market.

If I may ask, where did you get 400 high output Leds without costing a
fortune? I'd be interested in cobbling together a UV unit myself.

cheers,

Ian

Hi all
While perusing "Instructables" I ran across a few references to people
making Printed Circuit boards with an exposure unit made of UV LED's. This
peaked my curiosity & I went & purchased 400 UV LED's, resistors, etc & am
slowly soldering together an exposure unit...If I ever get through it I will
post back.
