WebFigure 1.6 The `bathtub' curve. THE DEVELOPMENT OF RELIABILITY ENGINEERING. Reliability engineering, as a separate engineering discipline, originated in the United States during the 1950s. The increasing complexity of military electronic systems was generating failure rates which resulted in greatly reduced availability and increased costs.
WebAt the same time, the reliability of the device has increased rapidly along with improvements in semiconductor technology. Typically, for equipment that demands high r eliability, a semiconductor device failure rate of 10 to 100 FIT (1 FIT = 1×10-9 /hour) is required. In order to realize that level of reliability, naturally the reliability of the
