There are 819 kinds of Thermal Interface Material (TIM) - those greases, putties, pads and phase change compounds that go between hot electronic components and their heat sinks - and just as many ways to misuse them. This article covers all of them by stating: If a TIM disappoints, it is all your fault for making one or more of these silly mistakes. Never Learning How to Make a … [Read more...]
Cooling Solutions In The Past Decade
Introduction In 1995, a typical thermal design engineer was aware that removing heat was not going to get any easier in the next few years. A look back at the past ten years reveals that thermal management remained a challenging field. Fortunately, developments and improvements in thermal management hardware have assisted the electronics packaging community by enabling higher … [Read more...]
Advances In High-Performance Cooling For Electronics
Introduction The need for new cooling techniques is driven by the continuing increases in power dissipation of electronic parts and systems. In many instances standard techniques cannot achieve the required cooling performance due to physical limitations in heat transfer capabilities. These limitations are principally related to the limited thermal conductivity of air for … [Read more...]
Vibration Analysis For Electronic Equipment
This topic is rather esoteric and usually an afterthought in commercial and industrial applications. In military and defense electronics, it is one of the major drivers for design and product architecture early on in the design cycle with specific targets/budgets. As with junction temperature requirements in a thermal design, there are structural dynamic issues that need to be … [Read more...]
Metals For Thin Wires – Criteria Of Choice
When a designer has to deal with thin current-carrying wires, a number of thermal issues pop up: Joule heating, heat losses and temperature measurement. For standard lead wires, one usually wants minimal Joule heating and minimum thermal resistance (in order to maximize the heat losses). Minimization of heat losses may be important for a research environment. Maximum Joule … [Read more...]
