No, the cheap board houses don’t check for this stuff. They just build and send

I was pleasantly surprised last week when Seeed Fusion contacted me to
point out a problem where two vias were too close together (by a couple
of thousandths).  They asked if they could reduce the hole diameters
I had the same good experience with PCBway.

I used these 0.9 * 0.9 mm GaN FETs, and that does not mean 0.9mm gate length:

and used the proposed Altium footprints from EPC. These pull the
solder mask onto the pad which is unusual but maybe essential for
a smooth soldering experience. I'm sure that EPC have experimented with that.

PCBway emailed me directly and we cleared that up that it was intentional.
They still produced the board on the same day, and soldering was easy.
Very satisfied customer.

Nevertheless I'll try JLCpcb next week. They now have a proxy man somewhere
here in .de who gets one box from China a day and forwards the contents
to the different customers after the customs work is done, via normal local registered mail.
The import VAT is then already done and billed by JLCpcb.
DHL Express is a royal pain to deal with.

Cheers, Gerhard
