Many companies design products with electronics that must function reliably at high altitude, typically 1,500m (5,000 ft) or 3,000m (10,000 ft) above sea level. Estimating the increase in operating temperatures is necessary to design and qualify such products. There are a variety of corrections used to account for this effect, many of which sacrifice accuracy for simplicity. … [Read more...]
Heatsink attachment and thermal interface effects on production assembly and repair
Today's market offers many heatsink attachment and thermal interface options. Your design decisions usually aim to optimize product performance at minimum cost. Secondary effects, not always sufficiently considered, significantly impact production cost, delivery performance, and reliability. These effects stem from the impact of the heat sink attachment design on the product … [Read more...]
Graphite fiber reinforced al and cu alloys for thermal management applications
Technological advances in the electronics industry have revolutionized the way the world communicates and conducts business. Today's electronic products, from cellular phones to sophisticated imaging satellites, demand lightweight, low-cost materials that provide more functionality in less volume. To meet these challenges, electronic systems must dump large amounts of waste … [Read more...]
Disk drive reliability and thermal management
Disk drive reliability and thermal management Hard disk drives are electromechanical systems which store information. They are the most complex electronic sub-assembly within a computer. If a microprocessor can qualify as the "heart" of a computer system, a disk drive can qualify as the "brain". Drives store and retrieve data in milliseconds, measured as access and transfer … [Read more...]
Pressure drop coefficients for thin perforated plates
Almost everyone working on pressure drop coefficients of perforated plates encounters the work of I.E. Idelchick {1}. A plethora of graphs or equations - some of which are impossible to evaluate quickly - must then be addressed. To simplify this issue for the reader, this month's Technical Data page has been designed to provide an overview of this information. When focusing on … [Read more...]
