JLCPCB can not produce the chamfered edges
I just tried to order the PCBs from JLCPCB. They wont produce the chamfered edges because the minimum required board size for the chaamfer is 50mm. Maybe you should add that to the Readme to make the ordering process smoother.
I also ordered some boards from JLC just now, but they seem to have accepted them for production without a hitch. Though you are right, their docs say "3. A board with a size of smaller than 5x5cm will be too small to be beveled.". Weird.
Interesting. I did not run into that issue. I could panelize the boards, connecting two at the long non-beveled side. IIRC they can bevel opposing edges.
@MarcSN311 I've panelized two of the boards. Feel free to try uploading this file to JLC: fab_panel.zip
EDIT: Updated fabrication zip file to un-flip text on upper board EDIT2: Remove redundant subdirectory from zip file
@DanielG they accepted my production files as well but then reached out to me to tell me they could not do it. @TobleMiner Thanks, i'll give it a try.
@MarcSN311 Did JLC approve the files yet? I'd love to update the repo with a panelized version.

I was able to get an order in and approved yesterday. Shows in production now.
Sorry I'm a bit slow. I will inform you as soon as my production files are confirmed.
No worries. I'm not in a hurry. Just want to make sure you are keeping us all up to date :smile:
I've had fab_panel.zip rejected because it had too many files; I assume this is the embedded fab_panel directory. Having removed that from the zip it seems to have been accepted.
I was able to order revA.zip quantity 10 pieces without issue. It might be you weren't ordering a large enough quantity.
Nope, I ordered 10 off as well. Based on experience so far, I think it's just as likely that there's little consistency in the checks JLC perform!
Hi Sir/ Madam, there are too many files in your zip file and we don’t know which file we should use, so could you please delete useless files in your Zip file?You can click ‘Replace file’ button to re-upload the file in your JLCPCB account page .Thanks.
Oops, the subdirectory is not supposed to be in that zip file. I've updated the zip file above again (actually final this time, I promise!) so JLC won't be confused by it anymore.
Just received my order! I had the same problem with the duplicate files, but they did not complain about the chamfered edges anymore. Sadly they did not produce the chamfered edges anyways -.-
I think the chafers are just nicer to your PCIe slots. I am just annoyed by thefact that they exchanged a bunch of messages with me about the chafer and in the end they did not produce it anyways.
Indeed, the production run JLC did for me also silently disregarded the chamfered edges. I think with careful insertion into the slots it shouldn't be that much of a problem. Aside from that, there's always the option to file the edges by hand, but FR4 dust is also not particularly healthy, to say the least...
I ordered 5x of the latest and got received 4, one did not survive fab. May be related to difficulty in chamfering.
@neobenedict It is not a particularly big issue. However it makes insertion easier and increases the lifetime of the PCIe slot.
Is this order HPE FlexibleLOM to PCIe adapter from https://cart.jlcpcb.com by your notes for ordering ok.

Other than that I'd suggest selecting "Specify a location"at the bottom of the page this order looks correctly configured to me.
Depends on whether you want 10 boards or 10 adapters, since there are 2 adapters per board. With edge chamfer and ENIG the prices at JLC are:
5 boards: $20 10 boards: $25
Most of the price is a one-time fee for surface finish and edge chamfer.
10 boards or 10 adapters
The difference between the two are what? The gerber files you upload on the site? Boards are fab_panel.zip and adapters are revA.zip?
I tried uploading the fab_panel.zip and got a quote for $29.20 (qty 10) with the settings are shown on the pdf from jbaznik. That sound right or should i upload revA.zip and do the same settings from jbaznik?
Yes, the panel contains two adapter boards each. However, getting the panel made costs the same as ordering just single boards.
$29 sounds about right? Does that price include shipping? My previous numbers were probably e bit off since I guesstimated them from Euros.
So the grand total is $44 with fab_panel.zip. The boards were $29 and shipping with Fedex was $15. I added gold fingers to try and reduce some oxidation over time but that was probably not needed (i didn't see a price increase with that option). TobleMiner do you have a way to contact you outside this github issue?
@the1cyrus Sure, feel free to write me either DMs on Twitter (https://twitter.com/Toble_Miner) or contact me by E-Mail: tobleminer(at)gmail(dot)com
Just fyi for everyone.. JLCPCB charged me an extra $25 because I used the paneled boards (fab_panel.zip). "Hi Sir/Madam,the special price is only for the single board and not for the panel board,so you may need to pay for an extra cost for it."
Unfortunately review is very inconsistent at JLC. This kind of stuff seems to depend heavily on who exactly reviews your gerber files. Not that I'd recommend this, but sometimes just cancelling the order and resubmitting it might work wonders.
