LM’s comparison list between different
norms from Copper alloys
Please read below on the wished for trade-name in the left hand column, and get it translated into LM-language on the right-hand
column. The right hand column with our name is either identical in composition or a fully replaceable alloy with only minor differences.
The column in the middle states the norm and its country of origin.
With no marks in front of LM’s alloy = alloy is identical, with this sign “~” = alloy is very similar, fully replaceable.
己達十萬甚至百萬以上。國際著名的計算機公司IBM(國際商業(yè)機器公司),己采用銅代替硅芯片中的鋁作互連線,取得了突破性進展。這種用銅的新型微芯片,可以獲得30%的效能增益,電路的線尺寸可以減小到0.12微米,可使在單個芯片上集成的晶體管數(shù)目達到200萬個。這就為古老的金屬銅,在半導體集成電路這個zui新技術(shù)領(lǐng)域中的應用,開創(chuàng)了新局面 [1]? 。引線框架
為了保護集成電路或混合電路的正常工作,需要對它進行封裝;并在封裝時,把電路中大量的接頭從密封體內(nèi)引出來。這些引線要求有一定的強度,構(gòu)成該集成封裝電路的支承骨架,稱為引線框架。實際生產(chǎn)中,為了高速大批量生產(chǎn),引線框架通常在一條金屬帶上按特定的排列方式連續(xù)沖壓而成??蚣懿牧险技呻娐房偝杀镜?/3~ l/4,而且用量很大;因此,必須要有低的成本。
銅合金價格低廉,有高的強度、導電性和導熱性,加工性能、針焊性和耐蝕性優(yōu)良,通過合金化能在很大范圍內(nèi)控制其性能,能夠較好地滿足引線框架的性能要求,己成為引線框架的一個重要材料。它是目前銅在微電子器件中用量zui多的一種材料。
