Alignment Holes in an Unframed Stencil

[TimCambridge]

For prototyping, I would like to order a PCB/stencil pair with matching 2mm or 3mm alignment holes in the PCB and the stencil.

It's easy enough to add non-plated holes to the PCB and set the solder paste layer so there are matching holes, but will JLCPCB produce a stencil from the solder paste (GTP/GBP) gerber or do they process the solder mask gerber (GTS/GBS) gerber and use that?

If they use the solder mask gerber(s) to produce stencils I expect I can get round that by ordering the stencil separately, but it would be good to know.

Thanks.

Yes, order the stencil on the side by supplying a GTP or GBP. And add this in the comments :

       "按我的贴片层做，不要修改文件，谢谢！Please do not edit stencil ! 3mm holes are important ! Thank you !"

I've just spotted this on the JLCPCB "How to order a stencil" page. That's what I want, custom tooling holes 

Stencils ordered separately

If you forgot to order your stencil when you ordered the boards, or if you want to have custom tooling holes in the border.

Quick note : I ordered a stencil only from JLCPCB and it's been waiting for pickup for four days. If you only need that, maybe https://portal.multi-circuit-boards.eu/Stencil would be smarter.
