someone should make a jlcpcb bingo card. so far iโ€™ve got

โ€œasked to confirm thereโ€™s no copper in my gerbersโ€

and

โ€œincurred the fee for too many slotsโ€

@jacqueline "are you really sure you're such a cheapstake you want us to fuck up your castellated edges?"
@jacqueline I've wanted to make a PCB fab stress test board
@xssfox @jacqueline now I want to too.
@martin_piper @xssfox if you ask aisler nicely then they will send you some if theirs. they make super neat little conversation pieces re: the challenges of pcb production
@martin_piper @xssfox (my fav thing about this -- something i didn't previously know -- is that the closest trace width on this board is designed to fail. if those traces don't bleed into one another, then they haven't put enough copper on the panel or w/e
@jacqueline Do they test those coppered areas against a standard capacitance? It seems like it'd be a great way to confirm the spacing between the traces.

@brendan idk but we can ask @aislerhq

the does sound pretty clever tho

@jacqueline @brendan We just electrically/optically inspect the coupons.
@brendan @jacqueline It's not just about the spacing, but also about how those traces' edges look: How rough they are, and what their profile looks like, if they have an angle. Capacitance is only going to image a fraction of that.
@jaseg @jacqueline a frequency vs reactance plot would probably be pretty sensitive, but not straightforward to interpret. I can see why they do optical inspection.

@jacqueline

"the spacing from cutout to board edge is too narrow which may be broken"

"the copper trace seems not regular copper lines"

"there is bug in EasyEDA"

"the v-cut line will cut the fiducial mark"

"can we add 5mm edge rails on both sides to proceed"

"board size of your order exceed 200*250 mm, there may have several bad boards after production"

"your file is 2 layer, but the order info shows that it is 4 layer"

"please enlarge the space between indicate holes at least 0.25mm"

@jacqueline

Also, when they mess up:

"We found that there were copper leakage on the edges of several boards. Sometimes it is unavoidable and we will pay attention to this issue in the future. We hope you can understand."

@ve7fim i am certain that you specifically have a flag on your account that just says "yo this they/them does some weird shit"

@jacqueline

Most likely... They've been really good with all my weirdness. I only had to cancel two designs out of > 700. Those ones were just too weird, even for them.

@jacqueline the bingo card being of course made of fr4
@jacqueline
For a second there I thought you meant to use jlcpcn to make a PCB bingo card. Lol
@jacqueline "Cheaper to buy 30 than to buy 5" work? I get that one a lot. ๐Ÿ˜‚
