Hello.Thank you for your quick response,and sorry for that since this components were belongs to lCSC warehouse,so we couldn't change the stock or know when time it will restock,since JLCPCB and LCSC were different company. And the purchasing department forbids us to interfere in the purchasing plan. Sorry for this,thank you!
I think JLC just don't want to deal with semis at all by the looks of it. Stuff is vanishing and they are never restocking them :(Hello Chris,
For those parts in the JLC SMT parts library but shows LCSC warehouse, if match two conditions, 1, it is in Shenzhen warehouse, 2, the quantity in Shenzhen warehouse is larger than 100pcs, then we can use it. About the part you mentioned, the quantity in Shenzhen warehouse is less than 100pcs,so we can not use it, and it shows no stock in JLC SMT library,so sorry for your inconvenience.
So the only options are to:
1) Go into production and just not fit the missing parts. Buyers would have to fit them themselves.
2) Go oldskool and replace the whole IO IC's with mosfets, which would probably push the H5 release date back a fair bit and maybe cost more.
3) Look for somewhere else to assemble the PCBs.. which if they have to be shipped around, or sourced elsewhere, will take longer and be more expensive anyway.
4) Rip out the 3.3V drivers and put header strips to add a IO addon board on at a later date.
I'm open to thoughts, but assembly has become a huge problem lately with some other projects because of IC's being out of stock. Its annoying since JLC expanded SMT assembly capabilities, then have no plan to actually stock parts to assemble the stuff with! :roll: I really feel like JLC have screwed us all over with :(
I have sent 1 last plea email to JLC.. I said I need at least 350 of the buffers.. but I have to assume I will get nowhere. So need a plan on how to progress forward now.
