Haven't ordered from them yet but already hate them. Tried since yesterday evening, wasted many hours. It often does not recognize board outline, but even if it does, forget about slots. WTF is their Gerber viewer. It's a pure piece of shit. Even if you name gerber files according to their naming scheme (which BTW does not have mechanical layer for some stupid reason). And Outline layer should include outline only per their instructions (where to put slots then), but even simple square often does not work. it often recognizes layers improperly, for example paste layer as internal layer (and no option to manually change
). Export per their proteus instructions - fuck you, we won't recognize it properly. Out of 4 of my boards only one worked properly, one which did not have any slots.
All of that would be fine, if there was option to manually enter size and proceed further. But no, you are effing stuck
. Oh and their stencil has a catch, they reduce everything by 15%, no option to opt out. And you'll only find it if you dig further into stencil specs description.
BTW this is not about blitz particularly which does not support slots but process is common for everything.
