I use standard window pane glass to keep the artwork flush with the
PCB and have not had any problems.

Hi all,

I'm busy building a UV box for photosensative PCB's

I've read various posts about how you shouldnt use glass to cover the
artwork as it stop UV rays. I've also read a few post where they say don't
use perspex - use glass!

Which is it

Is anyone using glass successfully? Or is perspex better? Or nethier - is
there something else I should look at?

Thanks
