Did someone is able to create stencil solder past holes smaller than the pad ? or I miss something ? (What is the point to create a solder past mask greater than the pad ?) I try to put a negative coefficient but EasyEDA dont allow.

Hi Suggest that you create a round solid region in stead of Pad.   but it can't create in PCBlib....

we will think about it. thank you

@UserSupport, Thanks for reply, yes I know the tricks but It's not considerable for lib and everyday project. Perhaps just allow a negative coefficient do the job and dont involve a lot a of modification in the core.... Many thanks to all the team for your great product and for your reactivity Have nice day.

I have just raised this point in another discussion: [https://easyeda.com/forum/topic/Drc-errors-with-library-component-f42b0deca29a47df944623bbeff22184](https://easyeda.com/forum/topic/Drc-errors-with-library-component-f42b0deca29a47df944623bbeff22184)

@andyfierman, Nice thread, intersting. "...I think this has already been raised as a Feature Request but I think this isuue highlights the need for it to be supported sooner rather than later..." I agree :) Have nice day

I didn't notice this until I tried to do the same thing again.  It used to say Copy to Paste Mask Layer and once there you could edit the width of the track copied.  But now it says Expose Copper which is NOT what people need.  Can you go back to the old scheme please ?   All exposed striplines should have a barrier just overlapping them.  I've bodged it for now by taking a copy of the stripline, pasting it again as accurately as I can in the same place, then changing it's layer and reducing its width.  But it used to be so much easier and far more accurate.

I suggested the name change because the name in the last version wasn't clear what it meant to people unfamiliar with PCB terminology but not that the function should operate any differently.

Well I'm afraid it operates very differently now.  Totally useless in its current form.  The old version was the correct operation, maybe with the name change as you say.

@MikeDB, Could you post a Bug Report about this?

Hello, I push up this thread becauseI think it's a real need about "Paste Mask Stencil" edition or at least an option to reduce the opening size, It's a major leak for EasyEDA. A lot of component have bad reflowing result without good Past Mask layout, please think seriously about this option. Anyway thanks for this great tools. Have nice day

@rom1nux It will be implemeted at v6.2 Thanks

Hello @UserSupport, Yipha ! I'm looking forward to this version 6.2 ! Thanks a lot, have nice day

@UserSupport,, The negative expansion mask is so useful ! Thanks all the team for the good job !
