These days, many thermal engineers face the challenge of defining effective heat sink cooling solutions for high power processors and ASICs (Application-Specific Integrated Circuits). The usual practice would be to calculate a value of ΘJA (junction-to-air thermal resistance) for the combined package/heat sink assembly and compare it to the requirements of the … [Read more...]
Calculation Corner: Thermal Interactions Between High-Power Packages and Heat Sinks, Part 1
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...]
