We offer 2 Layer PCBs with an option of HASL and ENIG as surface finish, if you use small drills, castellated edges or small trace width/spacing it is required to choose ENIG as surface finish.
| feature | HASL allowed (simple) | ENIG required (complex) |
|---|---|---|
| min. drill diameter | ≥ 0.3 mm | ≥ 0.25 mm |
| contains castellated holes |  |
 |
| min. trace width/spacing (Cu 35 µm) | 200 µm/150 µm | 125 µm/125 µm |
| min. trace width/spacing (Cu 70 µm) | 225 µm/225 µm | 175 µm/175 µm |
