Does anyone know there a standard matrix of clearances part to part for Class 2 and Class 3 board design. IPC does issue a preferred matrix but they are so liberal they not so useful in the real world. Any suggestions would really be appreciated.

Yeh, the IPC courtyards are for old ladies. I want to say that at one time IPC was talking about a new set of rules. Maybe, 7351 - SMT Footprint Design Guidelines???

Anyhow, Jim Blankenhorn at SMTPlus [ sales@smtplus.com ] has done THE best job of developing layout rules for different classes of equipment.

Hi ACE, I design with a Minimum of 0.40mm Body to Body on 0805 Chip size down for hi volumne products, 0.60mm would be preferred.
