DirtyPCBs some board-houses have incorrect thickness #41

Looks like the folks at DirtyPCBs redid their site, now neither of the links on the wiki Parts List work anymore. Can the wiki be updated with the new links? (found by searching the Shares page)

Updated! Thanks!

Out of curiosity, what PCB thickness did you get (using 2mm option) from dirtypcbs? I got some 1.85mm PCBs and these are very loose in the USB socket.

rickard-von-essen commented 7 years ago

Some weeks ago I got a batch of 2 mm PCB's from DirtyPCB which where 2.06mm, the fits nicely. (And as a reference my Yubikey NEO is 2.33mm which is probably close to optimal.)

conorpp commented 7 years ago

DirtyPCBs uses a number of different board houses which is probably the reason for the inconsistency. Reopening issue to try to find a better PCB source to get something around 2.1-2.2 mm

Suggestions welcome

DurandA commented 7 years ago

I'll try FirstPCB and report back. Unfortunately only 2mm is available and I cannot find other suppliers with 2.1-2.3mm thickness without prohibitive prices.

What is the thickness of the unit sold on Amazon? Unfortunately I cannot order it in my country.

conorpp commented 7 years ago

It's about 2.05 mm. 2.1-2.2 would probably be better.

DurandA commented 7 years ago

I have very good experience with printed.cz. I just noticed they offer 2.2mm for an affordable price. However, they don't have low cost slow shipping options so it may be too expensive for hobbyists wanting to build a few units.

Hi where can I get a downloadable version of these files
u2f-zero-panel-gerbers-zip, u2f-zero-gerbers-zip so I can try to use a different vendor for printing or to make some changed

Thank you
