content: I have a design that uses parts from JLCPCB's assembly service. I'm not able to order as JLCPCB hasn't had a part in stock for weeks/months. The frustrating thing is that LCSC has thousands in stock but they "have no way to transfer them".Can I order from LCSC and have the part sent directly to JLCPCB? Support advised me to order the parts from LCSC then ship them to JLCPCB myself, which seems a bit inefficient (and expensive). Strangely, JLCPCB's global sourcing doesn't allow you to order from LCSC. The part is from an Asian manufacturer and is not available from western distributors.

content: You could have the parts sent to a freight forwarder in China, then to the C.M.

content: Quote from: tooki on June 04, 2025, 07:34:49 amFair point. A single part could be shipped directly from the supplier. The OP just needs to make sure his name is on the documentation somewhere, else it might lost.

content: I usually pre-purchase the parts in JLCPCB's website. Is that the global sourcing you mention? I can't recall what it's called.

content: Figured I'd give an update. I ended up requesting a quote for the part. It took a few days after payment for the parts to arrive. I can now use the parts in an order.

content: I'm thinking of doing another assembly with JLCPCB but I need a part that is not stocked at LCSC at all.I've so far only had them do assemblies with stuff in stock at LCSC and I've not seen any other options during the orders I've done for how to otherwise source parts.What is the official process for having them source a part that doesnt' come from LCSC?

content: In this case it's a part from a Chinese manufacturer, but I can only find it in western distribution:https://www.digikey.com/en/products/detail/quectel/BG95M3LA-64-SGNS/13278150Not sure how that works. Would suck to have it ship from Digikey and get dinged both ways.

content: Quote from: Smokey on September 03, 2025, 06:39:39 amprobably worth contacting thr manufacturer to see if it can be shipped from their Chinese distribution direct, or ask JLC if they can source it locally

content: funny. I just asked the JLCPCB chat person if they could source that part and they sent me a link to JLCPCB where they have it in stock..https://jlcpcb.com/partdetail/Quectel-BG95M3LA_64SGNS/C2960993I asked what the difference with LCSC was, and they said they are "brother company" but have different stock and prices might not even be the same.With all the automation on the actual PCB fab side of things, they can't even manage stock between their two interfaces for effectively the same thing?

content: ..back for another rant...This time I have the same problem as the OP. Part in stock at LCSC, but not at JLCPCB. Will not just transfer. The chat guy solution was to just "pre-order" the parts at JLCPCB and see what happens in 7-10 business days. No guarantees. Also I can't place my PCBA order until the parts arrive, so they are missing out on an order.Paging JLCPCB EEVBlog rep guy...@JLCPCB OfficialIf LCSC is your "brother company", you have one seriously dysfunctional family.
