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!
