Stencils from JLCPCB

Hi, I am wondering how much control we might have over stencil? Right now, I imagine the stencil is cut from the top mask layer? Ideally, I'd like to be able to reduce the size of the pads; as it stands, I find the stencils end up dispensing too much paste. If I could have control over that, that'd be great!

@martin, The stencil is created from the Top (and/or Bottom) Paste Mask layer(s): ![image.png](//image.easyeda.com/pullimage/OpIWpeABN1KWk1oTm2lltYSr1l8vLY5c4UhTZMnz.png) You can increase the paste mask aperture but you cannot reduce it (i.e. a negative Paste Mask Expansion is set to zero although there is a minor bug in the GUI as I will post about later).

@andyfierman Right, of course! But- EasyEDA folks: would be very useful to have a global expansion (with negatives working!) percentage parameter.

Totally agree.  Same with the solder paste from copper layer transfer - a negative expansion is essential.
