PCB factory china tells you the Influence and control of solder mask
1. The thickness of the solder mask has a small effect on the impedance. The thickness of the solder mask increases by 10um, and the impedance value changes only 1-2 ohms.
2. In the design, there is a big difference between the choice of cover and no cover solder mask, single-ended 2-3 ohms, and differential 8-10 ohms.
3. In the production of impedance boards, the thickness of the solder mask is normally controlled according to the production requirements.
