Electronics are becoming smaller and smaller and the requirement to dissipate heat is constantly growing. The lack of an efficient thermal management strategy can lead to low performance, energy inefficiency, system failure, and even serious damage. With numerical simulation, such strategies can be tested early in the design process. This article shows how to use this … [Read more...]
Precision-Clad Composite Materials for Heat Spreaders in Handheld Electronics
The selection of heat-spreader materials is an important consideration for cooling modules in handheld electronic systems. Heat spreaders are typically used in close contact with the source of heat. This can be, for example, a subcomponent, chip, or microelectronic package. The heat spreader transfers and distributes heat from the source to a heat sink through a thermal … [Read more...]
Heat-Blocking Defects Detected Acoustically
In the landing gear control module of an aircraft, a high-voltage IGBT is about to fail. In the solder bonding one chip’s ceramic base to its heat sink are three small air bubbles—voids, in the vocabulary of electronic failures. The three voids are close together, and the largest is almost directly under a hot spot on the die. Collectively the voids have diminished … [Read more...]
Recirculating Chillers for Industrial Lasers
Industrial lasers are used for a wide range of applications including cutting, welding, micro-machining, additive manufacturing, and drilling. No matter the application, industrial laser systems generate a significant amount of heat. There are several different types of industrial laser technologies ultimately distinguished by the power density of the laser and its use. … [Read more...]
Headset Comfort Assessment Through Thermal Analysis and IR Imaging
Introduction Wearable technology is a growing market, projected to reach $2.78 billion in revenue by 2024 [1], and comfort is a major factor driving sales for these devices. Ergonomics and ease of use were cited as major factors in the decision to purchase a virtual reality (VR) headset in a recent consumer survey [2]. While weight and form factor are certainly ergonomic … [Read more...]
