Circuit board repair is a new repair industry. In recent years, the increasing degree of automation of industrial equipment, industrial control panels in various industries are also more and more, industrial control panel is damaged, the high cost of replacement circuit board (at least thousands of Yuan, many tens of thousands or hundreds of thousands of Yuan) has become the one thing very headache for companies. In fact, majority of these damaged circuit boards in the country can be repaired, and the costs of buying a new Board of 20%-30%, the time is shorter than the duration of the foreign Board. The circuit board repair basics are described below.
Almost all of circuit board maintenance are no drawings material, so many people on circuit board maintenance holding suspected attitude, although various circuit board vary, but not variable of is each species circuit board are is by various integrated block, and resistance, and capacitor and the other devices constitute of, so circuit board damaged must is which a or some a devices damaged caused of, circuit board maintenance of thought is based on above factors established up of. Circuit board repair detection and maintenance is divided into two parts, which detect occupies a very important position. For each device based on circuit board testing of knowledge, until bad find more change, then a piece of circuit board repair.
Circuit board test is for each electronic component on a circuit board fault tracing, identifying and correcting process. The entire testing process is the thinking and logical reasoning clues test process, therefore, test engineer required in the circuit board maintenance, testing and repair process, gradually accumulating experience, continue to raise the level. General electronic equipment is made up of thousands of components, maintenance, maintenance, if directly one by one test each of the components in the circuit board to find the problem is time consuming, can be difficult to implement. From symptoms to the cause of the failure is intended for maintenance, is an important method of repair. Circuit board as long as the problem was detected, so maintenance is easy. Above the circuit board repair basics are introduced.
