My terrible experience with Multi-CB (a German PCB manufacturer)

Over the last few years they have done about 300 different designs for me.
They once got in touch saying a pcb had been damaged and that they would credit me for that one.
I didnt expect for one minute they would send the duff one in with the good ones.
Sadly it got sent to a customer.
The only other time they messed up was partly my fault.
I had a pcb with some plated holes and none plated holes and the pcb's were sent back all plated.
So in the bin they went as they would short out on a heat sink.
I forgot to add a note about the none plated holes.
Although there were two distinct files, plated and none plated.

Rarely go wrong... unless you want to do assembly using chip they don't stock. They won't do it. In that way, PCBway is better because they will procure parts; but they do make a few mistakes, don't read the documentation, soldering is 7/10, and they are a little dim. But you get what you pay for.
Best company for quality PCB's I know of is Speedy in Taiwan, but relatively expensive. I once designed a tiny RF switching/DC feed board board for 1.6 GHz for a cost-sensitive satellite communications device, about 30mm x 20mm, using FR-4, double sided with single sided components. Insertion loss requirement had to be VERY low - something like 0.1dB. With impedance control, it cost me $800 for 10 samples of raw board! I was quoted $150 for the same board in the PRC, but I could not risk it. I tested the boards with a VNA, and the results seemed too good to be true. The boards were sent in approvals testing and they passed first shot. Speedy is not too speedy though because they provide excellent feedback prior to fabrication. They use state-of-the-art equipment and their communications in English is good.
I guess we get what we pay for.

How does that qualify as "going wrong"?! JLCPCB also won't sell you pet food or used cars. And they do not claim to do so. Where's the problem? :-//

Maybe "going wrong" isn't exactly the right term. At least VK3DRB did point out an important drawback of JLCPCB which is a valuable contribution.

Yeah they will. They now have the ability to procure parts for you. I think the only thing they don’t support is you sending components to them yourself.

That's news to me. It must have been a recent change. Thanks!
Rarely goes wrong, compared to PCBWay who don't read the documentation. Their silk screen top overlay is mediocre, with 0.6mm/0.12mm text being about their limitation. Not complaining though because these services are low cost and great for prototypes.
