how to pick right parts for assembly

hi, I am trying to design the very first PCB with assembly but when I go for order it shows no parts in the order. I guess I am not picking part names correctly. Here is an example part I am using and their info Manufactorer name:  STP16CPC26MTR JLPCB name: Extended Part  Supplier: LCS Almost all the parts have similar info.  Can anyone share a PCB design that I can order with full assembly, I am expecting with assembly they will procure parts and assemble it. Is that's correct? Thanks

Hello Thank you for writing to us here. About assembly there is two main needed files which are the BOM file and Pick&Place file (in .csv or .xls and .xlsx format) plus the GERBER of your PCB design. These assembly files must have some specific information in order to make our system detect the parts from the stock. Please check the following guide that explains the needed Headers for the BOM file (it also has a downloadable sample file) : [https://support.jlcpcb.com/article/80-bill-of-materialsbom-file-for-smt-assembly](https://support.jlcpcb.com/article/80-bill-of-materialsbom-file-for-smt-assembly) And kindly check this link that explains the information related to P&P file (also a sample file is attached there) : [https://support.jlcpcb.com/article/79-pick-place-file-for-smt-assembly](https://support.jlcpcb.com/article/79-pick-place-file-for-smt-assembly)<br> <br> Maybe you want to learn some info about our assembly capabilities so here is the related link : [https://jlcpcb.com/smt-assembly](https://jlcpcb.com/smt-assembly)<br> <br> Anything else, please let us know .

If you want JLCPCB to assemble your PCB then you need to choose parts from the JLCPCB Assembly library and then generate the BOM from the schematic and upload it when prompted during the PCB order process.

@sajjadakhter Please check the parts availability on our parts library through this link : [https://jlcpcb.com/parts](https://jlcpcb.com/parts)

ah i searched LED1642GWPTR its found on the [jlcpcb.com/parts](http://jlcpcb.com/parts) but when I am searching from within easyeda.com it shows it as 0 in stock. is that known issue or am I missing something?

Please read through this topic: [https://easyeda.com/forum/topic/Could-you-show-if-parts-with-zero-stock-have-been-re-ordered-0d9f8da8254c4b788193fddc9ea3901f](https://easyeda.com/forum/topic/Could-you-show-if-parts-with-zero-stock-have-been-re-ordered-0d9f8da8254c4b788193fddc9ea3901f)

@sajjadakhter As I explained in my previous comment, only the parts available at [JLCPCB PARTS library](https://jlcpcb.com/parts) are available for assembly, we at JLC could assemble most of LCSC parts but not all their parts, that's the reason why some parts are available at LCSC but not in our [parts library](https://jlcpcb.com/parts). Please consider that LCSC and JLCPCB have separated stocks but they share the same parts numbers to facilitate the parts availability search as same as EasyEDA, if you find the part available at our [Parts library](https://jlcpcb.com/parts) means that you can order it for assembly even when it shows 0 stocks displayed on EasyEDA. In near future we will expand our parts sources to cover the needs of our customers. Anything else, just let us know Thank you

so if i see part as 0 stock but LCSC shows in stock you would be able to get it assembled? but if LCSC shows as out of stock does that means you may not be able to get it (even though its in your library) as LCSC don't have it?

@sajjadakhter it is as simple as this : Parts are available for assembly if and only the parts are available at JLCPCB Parts library that you can check from here : [https://jlcpcb.com/parts](https://jlcpcb.com/parts)<br> <br> Anything else just let us know.

I think there is confusion around the term available. I assume the following is true? 1) if its listed in the jlcpcb library, with stock 100, 50 or even 0, then its considered "available", meaning available for assembly. Ie its an active part with jlcpcb. So i assume a part in the jlcpcb library, but with stock 0, then its possible to submit gerber, bom, etc and the order will be accepted. And the part showing 0 stock will come with the next internal "replenish" from LCSC 2) if its not in the jlcpcb library, then its not available.
