This paper, the fourth and final in a series downloaded by thousands of PCB designers, is dedicated to CAD library quality. It describes every aspect you need to consider when creating quad flat no-lead (QFN) component library parts.
It also describes the impact each feature has in the PCB process. To read this paper, click here.

The right decisions are not always the easiest decisions, but making them well and as early as possible often avoids errors and addition costs. This is certainly the case in PCB design and a key decision influencing the design process and the eventual outcome is the selection of material and of the materials vendor. This is even more important when the PCB requires significant performance parameters to be met, such as high speeds.

In the world of high tech, simplicity is arguably one of the foundational objectives of most of the technologies that surround us today. Certainly this is true in terms of how product designers are trying to create interfaces that allow even the most non-technical users to get what they need from electronic products with a minimum of hassle.
