PCB detection principle and computer examination principle about are easy to look after the test, first after the difficult.What does detection method of circuit board, please look down.
First: visually, through the visual understanding fault phenomenon, to understand the failure phenomenon helps to further the fault analysis, analysis of the process including ask, see, smell, and measured. Ask is to ask users fault phenomenon, is the fault caused by the improper use or in the normal operation of the sudden failure, there is to ask the board before there is no others repaired, what components.
Second: to watch is through careful observation of the electronic components, to see if there is no obvious discoloration, signs of burning, the existence of weld, welding and other phenomena. When necessary, it can be observed with a magnifying glass.
The third smell, smell have peculiar smell, once integrated circuits (especially high power devices) is burned out will smell of rotten eggs.
Fourth: Measurement and measurement, the measurement of the fault components, the measurement of the static measurement (that is, the electric measurement circuit board) and electric measurement.
STG electronic PCB can not only improve and solve the current PCB wiring design of some defects and shortcomings, and has a full set of advanced test equipment, test PCB signal of all state, meet the luxury car PCB board, the requirements of customers.
