But i sell nothing, i do just two copper last days for my personal use.
I see VDIP2 at RS-Composant for 21€ or in GB shop for 20£.
Print ".iff" with laser-printer on transparent paper, verify proportion (i print it with PC in 90% on my printer).
An pre-sensible epoxy 10minutes on sun for UV with printed-transparent and revelator and perclorure.
Or give the transparent at elecronic-shop, it can do the copper and drill it too.
Use v1.3, i hope correction is good on it (the 1.2 in photo demand modification).
If you no have electronic-shop at proximity tell me.
Sao Leopoldo it is in the south ? near Uruguay frontier ? i go sometime in the north Oyapoque(Amapa).
