At "Thermal Management in End Applications: Dissipating the Heat Away from the Base of LEDs" at the upcoming IPC Technology Interchange on Thermal Management: Getting the Heat Out, http://www.ipc.org/calendar/2010/thermal-conference1110/thermal-brochure-1110.htm, Sutariya will provide end product solutions countering the diminishing lifespans of Light Emitting Diodes.
"Transmitting heat to less critical areas and providing increased dielectric strength in LED MCPCBs results in increased thermal conductivity while lowering thermal resistance," says Sutariya. "The way to accomplish this is to focus on your needs and to control the fabrication notes by board-specific utilization of various materials to include metal heatsink / backing, aluminum core, metal core, copper or other metallic core, or heavy copper."
SOLVING THE CHALLENGES OF THERMAL MANAGEMENT
Other presentations and workshops included at Thermal Management Conference include:
Thermal Management in PCB Design from Concept to Manufacturing
This workshop will address how to develop an effective thermal management strategy and methodology, using real-world examples. Students will develop an understanding of how thermal analysis and modeling requirements change during the course of the design cycle, from conceptual to final thermal design and manufacturability. Some specific considerations covered in this session include:
* heat sink optimization at varying stages
* weighing the pros and cons of discrete versus monolithic heat sink cooling strategies
* copper distribution capturing
* the integration with board layout tools and how they benefit the designer as the cycle progresses

PCB Material Options and Properties Relative to Thermal Management
Designing for thermal management requires a thorough understanding of the materials available today. There are many different materials for thermal management PCB fabrication and they vary in thermal performance, electrical performance, and cost. Some designs may require high performance thermal materials; others may be able to utilize a more standard and economical option. This workshop will cover
* Standard and lead free compatible dielectrics (prepregs)
* Epoxy and polyimide films
* Metallic substrates (copper and aluminum)
* Formulas to help calculate which materials are necessary for your design
* Thermal and electrical characteristics as well as cost considerations
* How your material selection affects reliability of the components in your design
