@quixoticgeek@oshpark We had a number of snags in getting this set up quickly. Should be deployed soon, but for the meantime just plotting gerbers are the way to go.
@alexwhittemore@oshpark@thomasflummer 1oz is just a weight of total copper added, but clad/plated behave similarly in most cases. Only a few specialty applications need to consider the density+conductivity differences.
The ENIG is 3-6um, negligible for most applications. Usually only a factor for magnetics.
@TehTechnoGuy@oshpark On our Flex service, the milling is done with lasers, which can help somewhat. But the lasers can't cut through copper, so we have to split the annular ring. Should work fine in most cases, but it's not a risk-free solution either.
@TehTechnoGuy@oshpark You can try it, but the fab will use a 40mil or 68mil mil bit. In practice, it's very fiddly, prone to issues, and even when it does work, not ideal due to board height.
@leonkiriliuk@oshpark Generally this works, but castellations aren't fully supported since they may fail at random. Internal castellations have more quirks than normal ones: The outlines are sometimes confused for PNP data (often added incorrectly) and the cutout is ignored.
@_nitz@pimoroni@oshpark We used to do a matte finish for a while! It's indeed hecking gorgeous and we loved it, but we weren't able to use it long-term due to consistency across services and day-to-day production. If it's ever an option we can stick with though, we'd sign for it instantly.
@konsgn@oshpark Very not supported. Even if you specially prepare the file to get "processed" right on our end, the resulting board is going to have a high failure rate because of fab concerns.
@FrancoisGervai2@oshpark We'd need to see the files on this one. Just send em to [email protected]. It's likely a result of a ground pour generating thermals combined with some odd rounding/rasterization effects.
@RWB93174525@oshpark Oh yikes, sorry about that. This doesn't happen often, and indicates a fab inspection failure. Usually we pull them out and notify you, but sometimes we'll miss one. Shoot us an email, we'll get you sorted out.
@RWB93174525@oshpark@FrancoisGervai2@OSHStencils Generally speaking, castellations work fine, but almost always are imperfect and need cleanup to some degree. This is why we allow them, but don't offer support for them.
@RWB93174525@oshpark@FrancoisGervai2@OSHStencils In this case, it's likely our drill detection and trimming processes fighting each other, and having coordinates not rounding in your favor. Using a round hole, or pulling the hole inward a few mil will help. This is noted here:

@davedarko @oshpark Yep! Our dev's looking into this, along with a couple other small changes to the shared projects section. It'll happen eventually. :)
