Fabricator constraints

Overview of Quilter’s fabrication rules, detailing how they define geometric constraints for manufacturability and ensure compliance with fabricator capabilities.

Overview

Fabricator constraints are a subset of the overall constraints that define the minimum geometric thresholds a fabricator can apply when manufacturing your circuit board.

Specifically, Quilter's fabrication rule profiles include the following:

• Minimum trace width

• Minimum trace clearance

• Minimum drill hole size

• Minimum annular ring size

• Minimum edge-to-copper clearance

How Quilter uses fabrication rules

These are the absolute minimums that your fabricator will allow. Any smaller dimension defined later, including by specifying a netwidth, will be ignored or will generate a DRC violation.

How to specify

If using your own stackup, these will be read from your ECAD files. When using a Quilter stackup, these will be part of that definition.

In the Quilter app, you can double click a value to edit it.
