6.7.4 Large Asymmetric Components
6.7.4.1 Package Classes
From software FC5.1 on, the FCM Multiflex package type database contains the SMD
info files for large asymmetric component types as well.
In this case, component package types are grouped logically into package classes.
Each package class represents a number of component package types with the
same vision characteristics.
For example, package class SO goes for SO8, SOM16, SOL20.
A package class is built up from several information blocks. Each information block
contains parameters for specific vision aspects.
To get an impression of what data are involved in the various information blocks,
see the table below
