Figure 1: Telecom Equipment Operating EnvironmentsThere are two main reasons for doing thermal design in the telecommunication industry. The first is to ensure functionality of the equipment and system when subjected to extreme environments. The second is to ensure high dependability of the network. While doing thermal design, many challenges must be kept in mind: the … [Read more...]
Use of thermal analysis information in avionics equipment development
IEEE Standard 1332-1998 [IEEE 1998] requires that, "The [equipment] supplier shall determine the customer's requirements and product needs," and that, "The [equipment] supplier, working with the customer, shall include the activities necessary to ensure that the customer's requirements and product needs are fully understood and defined, so that a comprehensive design … [Read more...]
Design and reliability considerations in avionics electronics packaging
In the avionics industry, regulatory agencies and standards organizations, such as Federal Aviation Regulation (FAR) [1], Aeronautical Radio, Inc. (ARINC) [2], and Radio Technical Commission for Aeronautics (RTCA) [3], have developed sets of test procedures that help design engineers test and verify their designs and prevent any safety-threatening failures. Too often, however, … [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...]
