Hi,
I used in the past many pcb manufacturers, but for the last two projects I used PCBCart (excellent quality but expensive for a chinese company, especially compared to others), and PCBWay (electrically the panels were ok - I have also reflow soldered them and they work- but aesthetically the routing was poor in some points, as probably their router had a noticeable backlash).
I would like to try elecrow, but in this forum I read some disturbing posts (see
https://www.eevblog.com/forum/eda/elecrow-rant-or-how-ridiculously-they-screwed-up-a-panel-crappy-solder-resist/), especially with black and red solder masks.
I'm a bit worried, because this prototype will be very densely populated with small components (0402, SOD923, QFN, etc), with track/space 6/6 mils.
I know that if they screw up, they will remake the pcbs for free. However, DHL is such a pain in the ass, as not only they take 10€ just for handling customs, but also they won't calculate the custom fees based on the invoice and declared value (last time my order was 177€ - including shipping fees -, but DHL used the "statistical value" of 217€ - despite the invoice was attached!-, so I had to pay 10€+47€ instead of 39€ of custom fees. I.e. no matter if the boards costed 217€ or 10€, I will always have to pay something like 57€ in taxes, for each shipment with DHL!).
Anyone tried elecrow (black soldermask)? What was the min track/space you used ? (I read on elecrow "6/6 mils, 8 recommended". Why do they recommend 8?!?! That's disturbing! They are not sure they will manage to achieve 6/6?!?)
Could you post some pictures from elecrow?
Cheers!
