Hi guys
has anyone ever tried to make a 2 layers pcb with UV?
I always make my pcb with the UV ways, so I buy pcb with positive layer. Now I would like to do a 2 layer pcb, and I can't find any pcb with 2 positive layers, so I guess I should buy the positive spray (banzai sells it) and use usual pcb material.
Does anyone tried this way? it is easy?
how can I expose to UV a double layer pcb?
MG Chemicals makes double sided positive board, not sure if it's UV or not. http://www.mgchemicals.ca/products/600.html (http://www.mgchemicals.ca/products/600.html)
What's the link to the spray you're talking about?
thanks but where I can buy those pcb? I'm in europe
this is the spray: http://www.banzaimusic.com/Positiv-20-200ml.html
Mouser, try this part number: 590-650
thanks again, you're really kind but that looks way expensive for a pcb: 9€ + shipping (should be more than 20€).
should be better to buy the spray, I could use it for many pcb.
but I don't know how pratical it is

re the spray....don't go there - it sucks.
I buy my double sided pre sensitized board from these...

If you order more than 75€ from mouser, the shipping is free.
