How to provide clearance in soldermask layers
« on: March 16, 2022, 07:29:46 am »
Hi Guys. I just wanna know how can I provide clearance of a region where the soldermask has been opened and have two circular pads that needs clearance in Altium Designer? Any thoughts

Please restate your question. I think you’re using the word “clearance” to mean something different from what it normally means in Altium, so it’s not at all clear what you’re asking. (Which is why your screenshot has been viewed over 30 times without a single reply.)

looks like you made a hole that has no pad attached to it ... set your pad to hole diameter + desired clearance.

I normally make non-plated holes by setting the Pad to:
Layer: Multilayer
Hole size: [nominal]
Soldermask expansion: 3 mil
Soldermask expansion from hole edge: checked
Plated: not checked
Pad stack: simple
Pad size, X/Y: 0 mils

I guess you want to expose copper near the hole?  Then use plated or non-plated, but set the pad X/Y dimensions as desired, and soldermask with respect to pad.
