Master Bond has recently released its MasterSil 973S-LO, an adhesive, sealant and coating that passes NASA low outgassing tests. Well suited for use in vacuum environments, the MasterSil 973S-LO features a low volume resistivity of 0.004 ohm-cm, and is a silver filled compound that has a thermal conductivity of 9-11 BTU•in/ft²•hr•°F [1.30-1.59 W/(m•K)]. It bonds to metals, … [Read more...]
Thermal Facts and Fairy Tales: Fairy Tales About Heat Sink Performance Calculations
Clemens J.M. Lasance, Guest Editor, Philips Research Emeritus, Consultant@SomelikeitCool When Peter Rodgers invited me to again write a Thermal Facts and Fairy Tales (TF&F) column, I immediately thought of a recent webinar on basic heat sink calculations that I attended, in order to get an idea of the current status-quo in these matters. Well, in my humble view there was … [Read more...]

Controlling Device for Rotational Speed of Fans with PWM Control
Sanyo Denki has released the “San Ace PWM Controller”, a device for controlling the rotational speed of fans that have PWM control function. The controller’s main features include: reduced system power consumption and fan noise, the ability to be common-powered by the fan power supply of rated voltage 12, 24, and 48 VDC (with no separate supply required), and having a maximum … [Read more...]
Calculation Corner: Spreadsheet-based Matrix Analysis – Extension to Transient Analysis
by Ross Wilcoxon, Ph.D., Associate Technical Editor Over the years, a number of articles [1-3] published in ElectronicsCooling have described the use of thermal resistance networks to analyze electronic systems. The analysis of a thermal resistance network begins by defining discrete nodes that are connected with resistors, with the magnitude of a flow between nodes defined … [Read more...]
