一、计算机维护大部分是一级(板级)维护 一提到计算机的维护有人就会联想到和其它电器设备一样,用万用表、示波器、逻辑笔等工具去维护。其实,由于大规模、超大规模集成电路在计算机上的应用,使其集成度变得越来越高、体积变小、结构变得更紧凑。如轻易动手很容易造成短路或断路,一不小心就会使故障扩大化甚至把没有故障的计算机弄出故障来。这就是刚涉足计算机维修领域的初学者最
First, most of the computer maintenance is a (board level) Maintenance Mentioned in the maintenance of the computer Some people think of and other electrical equipment, with multimeter, oscilloscope, logic pen and other tools to maintain. In fact, due to large-scale, very large-scale integrated circuits in the computer application, so that its integration becomes higher and lower, smaller, the structure becomes more compact. Such as easy to use is very easy to cause a short circuit or open circuit, accidentally make the failure to enlarge or even failure of the computer to fault. This is the beginning of the newly involved in the field of computer maintenance most
