AISLER’s PCB Design Rules
Last Updated: 13/05/2024
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.
| feature | Simple | Complex |
|---|---|---|
| min. drill diameter | ≥ 0.3 mm | ≥ 0.25 mm |
| no. of layers | 2 | 4 |
| contains castellated holes |  |
 |
| min. trace width/spacing | 200 µm/150 µm | 125 µm/125 µm |
