PADS Paper, Part 4: QFN Components


Reading time ( words)

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

Streamlining Thermal Design of PCBs

01/10/2018 | Dr. John Parry, CEng, Mentor
When designing a PCB, thermal issues are often locked in at the point of selecting and laying out the chip package for the board. After that, only remedial actions are possible if the components are running too hot. Assumptions made about the uniformity of the airflow in these early design stages can mean a disaster for the commercial viability of a PCB if those assumptions are incorrect. A different approach is needed to improve reliability and to optimize board performance. Dr. John Parry of Mentor explains.

Tom Hausherr Discusses PCB Libraries’ BOM Builder Service

03/15/2017 | Kelly Dack, CID+
PCB Libraries CEO Tom Hausherr and Editor Kelly Dack discuss PCB Libraries’ new BOM Builder service during IPC APEX EXPO. Equipped with the new LEAP technology, the BOM Builder can potentially save PCB designers days or weeks of time normally spent turning a BOM into a CAD library.

The Fundamentals of Improving PCB Thermal Design

10/03/2016 | Gabriel Ciobanu, Continental Corp., and Boris Marovic, Mentor Graphics
Continental's automobile engineers have years of experience building critical parts and systems for automobiles. Making sure that automotive electronics are reliable, safe, and properly designed begins at the component level. Heat must be addressed early in the design process for these goals to be achieved. The most important thermal resistance for heat, outside the IC package, is the PCB.
