Hi,

I am a new user here. As per my knowledge in FP Designer you can edit the full pad stack (Top, Solder Mask and Paste Mask) in "Pad Stack Manager". 

Also you should select the layer you want to edit and change the values for both the Top and Solder Mask separately.

We fixed this FP Designer Chamfered Pad Solder Mask issue and re-released V2017.17. 

Try the updated version.

Thanks.

0.05 mm pad chamfer = 0.075 mm solder mask chamfer to keep the 0.05 mm oversize. 

This is good idea.

The other idea about creating a new pad stack in Pad Stack Designer is unsatisfactory, because It creates a 0.10 mm solder mask chamfer and the annular area is narrower than 0.05 mm.

Unfortunately, you have to figure out the solder mask chamfer size for the solder mask layer. 

0.05 mm pad chamfer = 0.075 mm solder mask chamfer to keep the 0.05 mm oversize. 

Or you can create a new pad stack in the "Pad Stack Designer" with a 0.05 mm solder mask over size and it will auto-calculate a new pad stack. 

Then swap out the pin numbers with the new pad stack in the "Pad Stack Manager".

I knew. I use the pad stack manager. But The program has only a Chamfer's length.
 
All I want to do is to have a gap between Top and Solder Mask Top.

In FP Designer you can edit the full pad stack (Top, Solder Mask and Paste Mask" in "Pad Stack Manager". 

Select the layer you want to edit and change the values for both the Top and Solder Mask separately. 

Note: the solder mask chamfer will be slightly larger than the Top pad. 

Let us know if you need a webcast training session and we'll set it up immediately.

I usually use FP Designer.

Then I have a question regarding the corner chamfer.
 
The component picture has the solder mask oversize 0.05 mm equally.
 
 

I edited the pad stack to use the chamfer feature. 

But but how do you make the solder mask oversize 0.05 mm equally?
