Trace / copper thickness
The following table shows the maximum permissible conductor width with minimal interconnect distance, depending on the copper thickness.
Inner / outer layers
copper thickness | Conductor width / distance min | Annular ring min. |
---|---|---|
18µm | 150µm | 250µm |
35µm | 250µm | 250µm |
70µm | 350µm | 350µm |
