1.离线检测
测出IC芯片各引脚对地之间的正,反电阻值.以此与好的IC芯片
进行比较,从而找到故障点.
2.在线检测
1)直流电阻的检测法
同离线检测.但要注意:
(a)要断开待测电路板上的电源;
(b)万能表内部电压不得大于6V;
(c)测量时,要注意外围的影响.如与IC芯片相连的电位器等.
2)直流工作电压的测量法
测得IC芯片各脚直流电压与正常值相比即可.但也要注意:
(a)万能表要有足够大的内阻,数字表为;
(b)各电位器旋到中间位置;
(c)表笔或探头要采取防滑措施,可用自行车气门芯套在笔头上,
并应长出笔尖约5mm;
(d)当测量值与正常值不相符时,应根据该引脚电压,对IC芯片正
常值有无影响以及其它引脚电压的相应变化进行分析;
(e)IC芯片引脚电压会受外围元器件的影响.当外围有漏电,短路,
开路或变质等;
(f)IC芯片部分引脚异常时,则从偏离大的入手.先查外围元器件,
若无故障,则IC芯片损坏;
(g)对工作时有动态信号的电路板,有无信号IC芯片引脚电压是不
同的.但若变化不正常则IC芯片可能已坏;

ABB在钢铁及有色金属行业已经耕耘百余年,在国内也从上世纪八十年代开始就为国内大型钢铁企业提供电气和自动化控制系统解决方案。经过百年的行业经验累积和技术沉淀,ABB已经能够提供完整的电气化、自动化和智能制造解决方案,迄今为止,已经为全球钢铁及有色金属制造商提供了超三千套技术解决方案。
在谈到如今发布钢铁及有色金属行业智能制造解决方案的背景和初衷时,ABB钢铁及有色金属业务北亚区及中国负责人蒋海波表示,ABB深刻洞察到钢铁及有色金属行业近几年压力很大,一方面是原材料价格的上涨、低端产能的过剩和高端产品的不足,另一方面,环保、低碳等要求越来越严格,企业亟待通过数字化和智能化技术来转型升级。但在这些行业的数字化转型过程中,很难找到合适且专业的解决方案供应商,很多情况是流于表面,为了数字化而数字化,并没有真正实现数字化转型的价值。
