New Standard DRC Specifications: Prototype PCBs with Smaller Features!

Previously, our standard manufacturing service design rule check (DRC) specifications were limited to 6 mil spacing and 12 mil drill. Today we announced that our standard manufacturing service will change to 5 mil spacing and 10 mil drill! The minimum annular ring size also drops from 6 mil to 4 mil! This means that you can design your PCBs to be smaller and more compact than ever before on the MacroFab platform and still be under our affordable prototype class level service and 10-Day Quick Turn Service.

We hope our new smaller design rules for our standard manufacturing service will accelerate the prototyping process for electronic designers, businesses, and engineers around the world. We can’t wait to see what you will build!
