Manufacturing Constraints Fabrication Tolerances: Allowable Variations in Dimensions for Manufacturing Here is a list of common fabrication tolerances for PCB manufacturing, excluding silkscreen and solder mask, that can be addressed in the Constraint Manager. For a complete list, please refer to the Appendix section of this document. Board Outline Dimensions: Tolerances for Overall Board Size and Shape Purpose: To define the physical boundaries of the PCB and objects near it. Impact: Creating proper constraints for board-edge ensures that all components and traces fit within the specified board dimensions, crucial for manufacturing and assembly, especially for panelization of multiple board designs from one copper sheet. Steps: You can set various outline-to-object rules within a constraint set. To do so: 1. Open the Constraint Manager. 2. Go to Manufacturing > Design for Fabrication > DFF Constraint Set > Outline spreadsheet.
