Study of Time for Preventive Maintenance of the Electronic Equipment

One of the important characteristics of reliability of electronic equipment is maintainability, and by definition is required to timely troubleshoot the failures through preventive maintenance. An analysis of maintainability is especially important for the electronic devices of high cost, which are used in complex and uninterruptible processes. For the analysis of the maintainability of the electronic devices it is necessary to define two indicators - the time for preventive maintenance and the interval reliability. There are many methods for determining the time for preventive maintenance. With constant productivity (load) of the used electronic equipment, the definition of the time for preventive maintenance is in relation to the service costs and the productivity program. In most case, the production program is variable, as well as the productivity for a given period of time of the electronic equipment. As a whole, it is associated with different electrical and thermal operating and environment conditions.
