Hello, please forgive me if this has been covered before. I have been making printed circuit boards for a long time now in small scale production, but I need to go cheaper, faster and even bigger. My question is, does any one know where to buy pre-sensitized clad, developers, and etching solutions on a large scale? Mouser, Digikey, Jameco, Datak and the like are expensive and the clad is too small to panelize. Google is so frustrating for this, I usually only find Ali Babas market or production houses that charge 50 bucks for a 50 cent board. For the curious, I'm making security products for industrial use.

Thank you, Rachel.
