1 我国电子设备维修领域需要器件级维修电子仪器、设备的电子电路部分,主要由焊装有许多电子元器件的电路板电路组成。电路板上的元器件故障,会导致电路板的故障,结果使整个设备不能正常工作。购买新的电路板,替换掉故障电路板(板级维修),往往费用很高;与发达国家相比,我国的设备服役期长、更新慢,很多国外厂家已经停产的设备仍在使用,所以还会有买不到电路板而使整个设备停机的情况发生。如果设法检测出故障电路板上的故障元器
1 China’s field of electronic equipment maintenance needs of device-level maintenance of electronic equipment, electronic equipment part of the circuit, mainly by welding with many electronic components circuit board circuit. Components on the circuit board failure, will lead to circuit board failure, resulting in the entire device does not work. Buy a new circuit board, replace the faulty circuit board (board level maintenance), often costly; compared with developed countries, China’s equipment, long service life, slow updates, many foreign manufacturers have been discontinued equipment is still in use, so There is also a situation where the entire device can not be shut down without buying a circuit board. If you try to detect the faulty board on the faulty component
