IPC-6012 Solder Mask Dam Requirements

The solder mask dam is the strip of solder mask material remaining between adjacent mask openings. Adequate dam width prevents solder bridging and ensures proper mask adhesion.

IPC Class Min Dam Width Typical Application
Class 1 0.050 mm Consumer electronics
Class 2 0.075 mm Industrial, telecom
Class 3 0.100 mm Military, medical, aerospace
