The long awaited Amendment to the Surface Mount Design and Land Pattern 
Standard is now available.

The single change that had the most impact was reduced the fabrication 
and placement tolerances from 0.2 mm to 0.1 mm. As a result the 
recommended lands patterns for the following components were effected:

Chip Resistors
Chip Capacitors
Tantalum Capacitors
MELFs
SOD 123
TO 252/TO 268
SOICs
SSOICs
SOPs
TSOPs
SOJs
PQFPs
SQFPs
CQFPs
PLCCs

We have conveniently reprinted each effected subsection in its entirety with 
the new land pattern dimensions.

The Amendment is available to members for $10, to nonmembers for $20.
