PCB Categories

We categorize your PCB as “Simple” or “Complex”, depending on the feature complexity of your design. A board will be categorized as complex when it uses at least one complex feature. Please make sure to select Beautiful Boards HD (Surface Finish: ENIG) if your copper design includes small line widths and/or spacings.
