Advanced Thermal Solutions, Inc. (ATS) has introduced the iTHERM-100 Test Station, a turnkey system of laboratory instruments and sensors for studies that require precise air flow velocity and temperature measurement. Applications include thermal management studies on boards, heat sinks, fans, ATCA cards, and racks. The iTHERM-100 Test Station includes a benchtop, … [Read more...]
High-Accuracy 2.25 V Digital Temperature Sensor with Dual Alarm
STMicroelectronics has announced a super-small and power-efficient temperature sensor allowing portable devices to benefit from features such as intelligent thermal protection. ST’s new STTS751 Digital Temperature Sensor (DTS) is mounted on the circuit board to feedback accurate temperature data allowing the system to manage its temperature, for example, by activating a … [Read more...]
The Better Box Model
Introduction For the consumer, natural convection cooling or fan-less cooling is the method of choice. It is silent, it is reliable, it is simple, and it is environmentally sound because no additional energy is used to remove the excess heat. For the thermal engineer, fan-less cooling is more problematic. On the plus side, no fan is needed, so there is an attractive cost … [Read more...]
Use of Power Law Regression in Packaging Thermal Calculations
Introduction In today’s demanding business climate, thermal engineers are often called upon to produce thermal analyses rapidly. For example, there is frequently the need for a quick calculation of a JEDEC-standard thermal performance metric, such as ΘJA (junction-to-ambient thermal resistance), for specific IC package designs on the basis of limited data. These metrics are in … [Read more...]
Technical Data Summary
ElectronicsCooling magazine has been providing a technical data column since 1997 with the intent of providing you, the readers, with pertinent material properties for use in thermal analyses. We have largely covered the most common materials and their associated thermal properties used in electronics packaging and as a result, this column will evolve into additional topics. … [Read more...]
