Hey Guys,
I have some old (2010) PCB Base material with expired photoresist. It's still perfectly good Bungard 35µm FR4
in the super-rare black and (some) blue - works a charm with Press N Peel or whatever other direct transfer
methods you might have, but is not guaranteed to behave with photo-litho processes. Just be sure to remove
the photoresist layer with alcohol or acetone or what have you before you try to transfer anything.
For those who don't know Bungard: This is MIL spec FR4 with copper from the Northern German Copper Affinery
a.k.a. Aurubis - qualifies for "nothing but the best for my dog".
I have dual layer:
And single layer:
Left on the top picture in the ziploc bag there are Eurocards (for size comparison).
You can mix and match and name sizes you would like, I also have some larger format stuff that
I can cut to size for you, 13€ for 500g incl. postage, packaging and fees.
