Go with jlcpcb, they don't charge extra for panels and vscore.

Here are some price quotes I obtained from the website pcbshopper dot com. Shipping to Eastern Canada, prices in Canadian Dollars.

qty = 10 price was CAD 17.28 (including shipping) from the lowest bidder

Hello Eric,
Yes, I have provided a separate gerber file containing 'v-score' layer in the middle in the attached gebers here.

Hello Luke,
I could do a GB if there is more interest (20-30 nos.), pcbs would be in 2.4mm thickness and 70um copper. So here is list
prasi-2 nos.
jameshillj-4 nos.
Luke-2 nos.

Otherwise I can order a batch of 10 pcbs from China and send you couple. Lets wait a day or two to see.

regards
Prasi

Seems jlcpcb needs the panels to be atleast 7cm x 7cm for it to process v-score . So i have removed the v-score layer in the attached gerbers.
one could manually score it and separate the pcbs if needed.

When i replaced the gerbers , it got approved immediately. see attached image.

Prasi, what about laying out another pair horizontally, separated with a v-score. The PCB price at JLC only goes up by $4 or so for 100x120mm and then you get double the boards and reach the minimum size for v-scoring.

Hi Prasi

This is strange because I sent your file (91mm x 56mm) to the same PCB house and there was no issue during the review, production was completed today. Have you tried twice?

Hi, Eric

Just curious, do you think you might be able to spare a pair (for both rail)?

Regards,

e_fortier 8th January 2020 02:02 AM

Yep, no problem.

Send me a PM w your complete shipping address.

Hello gtose,
I didn't think of that. Thanks . But I had already ordered. So for others I will do it and post gerbers.

Hi Eric,
I didn't try twice, just removed the vscore line and uploaded the gerbers.
Probably such manual checks at jlcpcb are person dependant , so you got lucky.;)
Regards
Prasi
