We pay again at the back end when temperature effects compromise the potential operational life span. Temperature rise has the highest impact on component life. In our world of electronic product design, we live by this rule of thumb: For every 10 degrees Centigrade rise in temperature, the average reliability is decreased by 50 percent.
