Cooling Techniques for Electronic Equipment, 2nd Edition
Many failures in electronic systems have been traced to large differences in the thermal coefficients of expansion and the lack of proper restraints or strain relief in the electrical lead wires. Many failures have also been traced to large dynamic. displacements developed in circuit boards when their resonant frequencies are excited during operation in severe vibration environments. These subjects therefore have been added to this textbook to promote a better understanding of other failure mechanisms that affect the reliability of sophisticated electronic systems.For many years the electronics industry has been striving to improve the reliability of electronics systems by reducing the operating temperature and the junction temperatures of electronic components. During this same period there has been a strong drive to reduce the size and cost of these electronic assemblies. Problems have resulted from these trends because the power densities have increased rapidly as the volume decreased. As a result, many electronic systems now require more exotic cooling techniques with special fans, liquid cooling, heat pipes, and thermoelectric cooling to keep junction temperatures under 100°C.
