Heat management for SMD, LED, and systems 1W to 50W

Do you use power MOSFETs, high power LEDs, power resistors, or hot processors in your design and want to avoid heat related system failures? This course covers the best options for you to manage heat cost effectively and reliably. It gives a good overview of PCB design to maximize SMD/LED heat dissipation. It also covers how to choose the right heat sink interface materials, heat sink designs, natural and forced airflow options as well as heat dissipation simulations (both mechanical and in software). We’ll go over some helpful tools, and break down thermal resistance equations to simple terms. Heat management doesn’t have to be scary. Take this class to know your options. Now with LED specifics!

An intuitive approach to understanding basic high-speed PCB layout

What is a wire? At high speeds, it behaves very differently from what we were taught in college! This is a presentation on high-speed basics that helps make the subject intuitive in a different way. Learn about how frequency enters the picture, high-speed signal propagation, impedance, noise, and reflections with easy-to-understand animations and analogies to understand this subject on a deeper level. Now covering cables!

Agenda

Heat management:

• Why do we care about temperature?
• A word about Physics
  • Heat in = Heat out
  • Basics of heat transfer
  • Heat Vs Area
  • Spread it out! (the key to thermal management)
  • Basic thermal modeling (simple math models)
• Semiconductor construction and heat
• Practical Thermal Guidelines
• Thermal management parts
  • Interface material
  • Heatsinks
  • Heat Pipes
  • Fans
  • PCB constructed heatsinks
• Design Example
  • 160W variable voltage power supply
  • Design flow (best practice)
  • Layout example
  • Make thermal/mechanical prototype (can be done before electronics!)
• Tools for measuring effectiveness
  • On board sensors
  • Thermal imaging cameras
  • Airflow measurement tools
• Conclusion

High speed 101:

• What frequencies are present in a digital signal?
• What is a transmission line?
• What is impedance?
• What are return currents and why do we care?
• Causes and solutions for noise
• Termination –why it’s helpful and when to use it
• PCB stack-ups, routing, diff signals, DFM
