I've used your service for about 5 different designs. You always had a look at the gerber files and sent me an export with remaining questions about the parameters or spotted possible errors in the design. I value this very much!
I would recommend your service to everybody who wants a professional manufacturer that actually has a look at the design before producing it.
Keep up the good work and greetings from Germany.
Webmaster's reply : Yes we have free DFM that check all files in details before production, that will avoid the possible problem after production that may need to remake the boards because of possible mistake in the design.
We are glad that our customers are get benefit from this process, thank you.
