  1. However, the die attach layer delaminated after 500 cycles and pcb cracked in the underfilled samples after long time cycling. c - sam is employed to investigate the delamination in the underfilled samples. highly concentrated stress - strain induced by the cte mismatch between the bga component and the pcb board, coarsened grain and two kinds of intermetallic compounds ( nisn / nisns ) which formed during reflow and thermal cycle and their impact on the reliability of solder joints are discussed in this paper

    充膠樣品粗化尤為嚴重； ? ni - sn金屬間化合物包括兩層：其中，靠近ni焊盤的那層比較平整，同時， eds結果分析表明其化學式近似為nisn ，而靠近焊料的那層呈板條狀，化學式近似為nisn _ 3 ，文獻表明其為亞穩相； ?充膠使得樣品最大應力范圍降了接近一個數量級並降低了dnp的作用，同時，器件失效模式變為晶元粘接層分層； ? c - sam結果表明本論文採用的充膠樣品，晶元粘接層分層起始於500周左右，而經過2700周循環的樣品，分層幾乎擴展到整個界面。
  2. 3 the experiment showed that there is no copper deposition in the film using p ( an - mma ) as polymer matrix. but the copper deposition and gradient distributing appears in the film when using p ( an - ita ) and p ( an - mma - as ) as polymer matrix. the size and number of crystal increases as the concentration of ita in copolymer increase and the film is prone to be ruptured

    3實驗顯示p （ an - mma ）作為基體制備的pmgcf五金屬沉積，銅的沉積量為零； p （ an - mma - as ） ， p （ an - ita ）兩種共聚物為基體時均出現金屬銅的沉積，二者金屬沉積相均呈現一定程度的梯度分佈形態，但p （ an - ita ）為基體時得到的晶體比較粗大，且隨其中ita的含量的增多得到粗糙晶體的數目增大，所制的pmgcf脆而硬，受外力沖擊時容易斷裂。
  3. Under the careful retrospection and analysis on the previous and recent experiments about mechanical behavior of nanocrystalline metals performed by almost main investigators, the dislocation and atomic diffusion is believed to contribute hardly to the deformation of nanocrystalline alloy, and a model based on thermal activation process was applied to fit the experimental data of nanocrystalline ag

    結果表明，納米晶金屬ag的不僅具有比粗晶ag高2 - 6倍的拉伸和壓縮強度，而且在大范性形變階段顯示了極低的加工硬化和應變速率敏感性。結合位錯理路和非晶合金形變特徵，提出納米晶金屬ag的塑性變形主要由於晶界滑移貢獻。
  4. The results indicate that arc melting is a good method to produce nb - si system intermetallics due to its simpler technics, lower cost and compact products. however, powder metallurgy is found to be not suitable to produce the nb - si system intermetallics due to its coarse and loose products resulting from the poor molding property of nb and si mixed powders. optical floating zone technology, which is used to fabricate nb - si intermetallic composites for the first time, is also found to be a good way to produce nb - si system intermetallics because of its compact products and good property despite of its relatively high cost

    結果表明，電弧熔煉方法制備得到的nb - si系金屬間化合物比較緻密，且制備工藝簡單，經濟實用，是一種合適的nb - si系金屬間化合物制備方法；由於nb 、 si元素粉末的成型性很差，用粉末冶金方法（熱壓燒結和冷等靜壓）制備的nb - si系金屬間化合物表面粗糙、緻密度低，且成本較高，不宜用於制備nb - si系金屬間化合物；首次用光學懸浮單晶生長技術制備的nb - si系金屬間化合物復合材料緻密度很高，盡管成本稍高，但由於性能最佳，也是一種合適的nb - si系金屬間化合物制備方法。
