I think Aisler is also sponsoring LibrePCB and accepts their CAD files (i.e. no messing around with gerbers).

I'm definitely testing them for my next boards.

I tried AISLER once, the PCBs I got were very good quality. They didn't work due to me using tolerances that were too tight (I couldn't easily find their tolerances on their site), they refunded me immediately and I re-ordered the fixed boards. Those were also very good quality.

Overall, I have a very good impression of them. If the price is acceptable for you, I would definitely recommend them. Shipping was very fast, too, the boards arrived within the week to Greece.

Seems to linked better now: https://aisler.net/help/design-rules-and-specifications/spec...

That still doesn't look very usable, as someone who designed a board, I don't know what the milling and drilling diameters are for. I know about track size, track clearance, minimum via diameter, etc.

The way they have it, I need to know about how PCBs are fabricated to read it accurately.

All things equal, I think I would go with them just because of this:

Chinese PCB fabs are extremely dirty.

Having been to Chinese PCB fabs recently, they're no longer extremely dirty. The major impact is international shipping.

That's good to know, thank you.
