3D ICs With TSVs - Design Challenges And Requirements

Heat Management in Printed Circuit Boards

This report discusses the significance of heat management in the design of printed circuit boards (PCB).

After an introduction into the basics of PCBs, the crucial mechanisms of heat transfer are discussed with regard to significance and typical design parameters. Emphasis is laid on ways to determine conductive heat transfer. Here, common techniques as well as considerations on how to model PCBs for simulations are shown. Finally practical examples are given to illustrate the prior discussed aspects.
