Summary
The CAD library is the starting point that affects every process from PCB layout through PCB manufacturing and assembly. There are dozens of things to consider when creating a CAD library that are often overlooked or not even considered that will directly affect the quality of the part placement, via fanout, trace routing, post processing, fabrication and assembly processes. Part 1 of this paper describes every aspect that should be considered when creating chip CAD library parts and the impact that each feature of the CAD library has in the PCB process.
