Hi, I have in my JLCPCB shopping cart waiting a board which had stock when I entered it, but since then it ran out of stock  Can not order the board any more. Also if you enter a new order, and component is out of stock, it will be left out of assembly-BOM. I.e. you cannot put the order on hold to wait for restocking to happen. Feature request: JLCPCB, make a ordering option so that zero-stock components can be used on SMT order, and the order stays on hold until all components are on stock. -Topi

@topirinkinen, "Feature request: JLCPCB, make a ordering option so that zero-stock components can be used on SMT order, and the order stays on hold until all components are on stock." Please post this as a separate Feature Request.

Hello ; We are grateful that you messaged us in this forum. Please consider that parts with zero stock will not be confirmed for assembly, so while you place the PCBA order there is a step where you confirm the parts that you are willing to assemble and the detected parts that  have zero stock will be not confirmed for assembly but you can select alternatives from the library (please note that you can directly browse the library to select the alternatives). Considering your request about the lead time, since only the available parts will be assembled then there is no delay on the PCBA and the turnaround is as same as 24-hours for the PCB assembly : [https://jlcpcb.com/smt-assembly](https://jlcpcb.com/smt-assembly)<br> <br> Please fell free to write to us here if you need any guidance or you can have the support of our team through [support@jlcpcb.com](mailto:support@jlcpcb.com)<br> <br> Thank you

Thanks for the response. I would strongly suggest we need at least a "Normally Stocking" flag on parts that indicate there is an intention to get more of a part (and better yet, an ETA in days of getting stock), not just that hypothetically it has a LCSC listing and therefore it maybe might be an assembly option one day? Otherwise, when doing part selection for design (which will happen long before a BOM is actually uploaded into JLCPCB) it's pot luck what you should be picking and even current stock levels is no indication of an on-going intent to stock. Thanks.

@david.s.zanetti Yes I understand your points and first let me thank you for this interesting conversation. Actually there is a plan to improve the Assembly service, the plan has started early last year and by now we are supporting +80K parts in our assembly Parts library (it was just 30K parts before) we have added more PCB colors to be supported for assembly and some other improvements and the plan still on going because we can't change the whole process in one shot (there is always a strategy to implement) soon we will add more new features and why not it will be available for customers to get them parts ordered from external suppliers such as Mouser and Digikey and assemble the parts by JLCPCB, also we are planing to support all the LCSC parts to be assembled in our lines. JLCPCB PCBA service is already good and could be improved so the positive side is that we are truly improving it and more best news are on the way that's why we are counting on your thoughts and feedbacks to progress. Thank you again.

Thanks for the update - it's appreciated.  I'll add my voice to the folk above - the sole frustration that I have with your PCBA service is the haphazard availability of parts. The concept of being able to place an order which includes parts currently out of stock, to be on hold until they are in stock, is a good one - if nothing else, it would give JLCPCB an idea as to which of the out-of-stock parts ought to be restocked.
