I'm designing a footprint for J-Link 10-pin Needle Adapter. The pads need "no solder paste". I've looked around all configurations for the pad but didn't find a method to remove solder paste, so my question is how to design this kind of "no solder paste" pad in Altium efficiently?

    \$\begingroup\$ Hey look. It's Tag-Connect. The reason you might not be able to find instructions is because it's trivial if you know what a solder mask is supposed to do. Just remove the solder mask in the padstack used for the pin. No solder mask = no hole in the soldermask = no solder applied. \$\endgroup\$

Edit the properties of the pad.

Set the Paste Mask Expansion to a large negative number (with absolute magnitude greater than the largest dimension of the pad).
