长期及大量的机场电子维修实践证明,对于使用时间较长、工作环境恶劣的电子设备来说,内部元件出现虚焊造成接触不良,从而导致设备故障的现象是屡见不鲜的,也是维修的难点之一。本文试图从虚焊产生的原因、容易产生的部位以及相应的对策等几个方面谈谈笔者粗浅的认识。 Long-term and a large number of airport electronic maintenance proved that, for the use of longer, harsh working conditions of electronic equipment, the internal components resulting in poor contact Weld, resulting in equipment failure phenomenon is uncommon, but also the maintenance of one of the difficulties . This article tries to talk about my superficial understanding from several aspects such as the reason of welds, the parts that are easy to be produced and the corresponding countermeasures.
