# Design Soldermask

#### This group consists of Design Soldermask constraints.
The rules are as follows:

- Soldermask alignment: Specifies the alignment tolerance required for the proximity of:
  - package soldermask to placebound
  - pad soldermask to pad geometry
- Soldermask to soldermask: Specifies spacing checks for:
  - pad soldermask to pad soldermask
  - symbol soldermask to symbol soldermask
  - symbol soldermask to pad soldermask
- Soldermask to pad and cline: Specifies spacing checks between the soldermask and pads or clines.
- Soldermask to shape: Specifies spacing checks between the soldermask and shapes.
- Pastemask to pastemask: Specifies spacing checks for:
  - pad pastemask to pad pastemask
  - pad pastemask to package based pastemask
