维修技巧之
维修经验总结
一.带程序的芯片
1.EPROM芯片一般不宜损坏.因这种芯片需要紫外光才能擦除掉程序,
故在测试中不会损坏程序.但有资料介绍:因制作芯片的材料所致,随着
时间的推移(年头长了),即便不用也有可能损坏(主要指程序).所以要
尽可能给以备份.
2.EEPROM,SPROM等以及带电池的RAM芯片,均极易破坏程序.这类芯片
是否在使用<测试仪>进行VI曲线扫描后,是否就破坏了程序,还未有定
论.尽管如此,同仁们在遇到这种情况时,还是小心为妙.笔者曾经做过
多次试验,可能大的原因是:检修工具(如测试仪,电烙铁等)的外壳漏电
所致.
3.对于电路板上带有电池的芯片不要轻易将其从板上拆下来.
二.复位电路
1.待修电路板上有大规模集成电路时,应注意复位问题.
2.在测试前装回设备上,反复开,关机器试一试.以及多按几次复
位键.
