維修技巧之
維修經(jīng)驗總結
一.帶程序的芯片
1.EPROM芯片一般不宜損壞.因這種芯片需要紫外光才能擦除掉程序,
故在測試中不會損壞程序.但有資料介紹:因制作芯片的材料所致,隨著
時間的推移(年頭長了),即便不用也有可能損壞(主要指程序).所以要
盡可能給以備份.
2.EEPROM,SPROM等以及帶電池的RAM芯片,均極易破壞程序.這類芯片
是否在使用<測試儀>進行VI曲線掃描后,是否就破壞了程序,還未有定
論.盡管如此,同仁們在遇到這種情況時,還是小心為妙.筆者曾經(jīng)做過
多次試驗,可能大的原因是:檢修工具(如測試儀,電烙鐵等)的外殼漏電
所致.
3.對于電路板上帶有電池的芯片不要輕易將其從板上拆下來.
二.復位電路
1.待修電路板上有大規(guī)模集成電路時,應注意復位問題.
2.在測試前裝回設備上,反復開,關機器試一試.以及多按幾次復
位鍵.

仲量聯(lián)行大中華區(qū)經(jīng)濟學家兼研究部總監(jiān)龐溟表示,總的來說,在極端高溫天氣、區(qū)域性限電、疫情散發(fā)等多種超預期、偶然性、外部性因素下,經(jīng)濟動能在一定程度上受到擾動,前8個月工業(yè)企業(yè)利潤仍在下降,且企業(yè)生產經(jīng)營成本繼續(xù)高企,顯示經(jīng)濟復蘇仍面臨較多不確定性因素、基礎仍不穩(wěn)固。
數(shù)據(jù)顯示,1~8月份,采礦業(yè)實現(xiàn)利潤總額11246.8億元,同比增長88.1%;制造業(yè)實現(xiàn)利潤總額40777.2億元,下降13.4%;電力、熱力、燃氣及水生產和供應業(yè)實現(xiàn)利潤總額3230.1億元,下降4.9%。
