Thanks for this information. No, I'm not after your secret formulas
It sounds reassuring that you have made efforts to make eco-friendly cards long-term reliable. One reason I asked was from graphics card baking from hardware forums to fix not-so-old-really unreliable cards.
Normally though, I understand that modern graphics card have higher PCB mask density and operating temperature extremes (among other things) to expose them more to lead-free weaknesses. While probably new and old Amiga cards require less layers and miniaturization. In your opinion, is this comparison true or could you make some other comparison (in numbers or such) that would point to your products being more long-term reliable, as it indeed seems they are?
