Soldermask clearance and solder bridge sliver

Vincent asked Dec 18,2023

What is the minimum solder bridge and solder mask clearance for matte black solder mask? I found it says 150um for solder bridge and 0.75um for soldermask to pad clearance, but it is not consistent with another source where it says that the pad to pad clearance should be 0.22mm.

    Solder Bridge Clearance: Typically 0.1mm (100um) to 0.15mm (150um). Solder Mask to Pad Clearance: Usually 0.05mm (50um) to 0.1mm (100um). Pad to Pad Clearance: Typically around 0.2mm (200um) to 0.25mm (250um).

    For advanced PCB,the minimum for matte black solder bridge is 5 mil, the minimum sample pad spacing is 7 mil, and for mass production, it should be 8 mil. 0.22mm is for standard PCB.
