Bruce Guenin, PhD Associate Technical Editor The need to accommodate increasing chip power has led to improved package and heat sink designs having much lower thermal resistance values than previously. This has led to challenges in accurately calculating the thermal performance of the package and heat sink as an integral unit on the basis of thermal resistance measurements … [Read more...]
Thermal Facts and Fairy Tales: Fixed Temperature and Infinite Heatsinking
In keeping with the name of this column, the fact worth reminding is that a fixed temperature boundary condition in a thermal simulation represents an infinite heat sink. The systems that thermal engineers model and simulate have boundaries and thus require some type of specification, usually known as boundary conditions. Related to the other part of the name of this column, … [Read more...]
SynJet Technology Helps Europe Go Green
Nuventix, Inc. announced it is seeing significant adoption of its SynJet technology across Europe, most notably in store installations of the region’s largest retailer. SynJet LED coolers maximize lumen output and extend the life of LEDs in the stores of Carrefour’s new hypermarket concept, Planet Carrefour. By delivering targeted pulses of air directly to the LED system's heat … [Read more...]
Micro Porous Ceramic Heat Sinks Enhance Heat Dissipation
AMEC Thermasol has introduced a new range of Micro Porous Ceramic Heat Sinks (MPCHS). Due to the open irregular structure of the Micro Porous Ceramic, the heat sinks provide a greater surface area to contact with the air compared to metal. Due to this structure, the heat sinks have excellent heat dissipation and heat convection properties. The MPCHS dissipates heat faster than … [Read more...]
Analysis System Ensures Optimal Heat Sink Efficiency
The new Tactilus® heat-sink analysis system by Sensor Products Inc. enables research and design engineers to quickly and precisely test and correct the surface contact and pressure distribution between the heat sink and semiconductor. With Tactilus, engineers can visualize actual contact forces and pressure distribution data on the circuit board components. As the mounting … [Read more...]
