Hi JLCPCB! I am unclear on whether designing a board for assembly which uses a part listed in the library but with stock 0 (and looks like always has stock 0) will just result in a longer lead time, or will not be able to be completed in a known timeframe at all. I would understand a longer lead time, but it's not obvious if stock 0 parts are "safe" to use for designs at all. I generally check if LCSC has any stock, and have started to assume that if they have non-zero stock it's probably going to just be more lead time to get it over to JLCPCB's assembly facilities, but this also begs the question how large an order has to be for that to happen? Or should I just avoid designing anything at all with stock 0 parts? Thanks.
