Design Rules for PCBs

MacroFab has 4 different sets of Design Rule Checks (DRC) for PCBs. Standard, Extended Manufacturing, Extended Drill, and Extended Manufacturing and Drill. Most PCBs fall under our Standard DRC. If you have any questions about your PCB design and what set of DRC to use, contact us!

For PCBs with 2oz (35μm) copper the minimal trace width, spacing, and annular ring need to be larger to account for the thicker plating of copper. 2oz Copper also disables the extended manufacturing option.

PCB Layer Stack Ups
