木工機械的安全.圓盤鋸床.第4部分:帶手工裝卸的多鋸條粗木鋸床Her cheeks were pink with health, and her large round arms carried the piled-up dishes with never a tremor.
她臉頰上泛著健康的桃紅色，兩條粗大、渾圓的胳臂托著那些疊在一起的盤子，一抖也不抖一下。But before pierre had time to make up his mind what answer he would send, the countess herself walked calmly and majestically into the room. she was wearing a white satin dressing - gown embroidered with silver, and had her hair in two immense coils wound like a coronet round her exquisite head. in spite of her calm, there was a wrathful line on her rather prominent, marble brow
可是皮埃爾心裏還沒有決定回答他的話，伯爵夫人就親自走進房裡來，神態安靜而莊嚴，穿著一種滾銀邊的白綢長罩衫，梳著普通的發型兩條粗大的辮子在她那漂亮的頭上盤了兩盤成了diadme ，不過在稍微突出的大理石般光滑的額頭上有一條憤怒的皺紋。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。The cmp experiment was carried out systematically on litao3 wafer. the polished surface foughness and material removal rate in different polishing conditions were measured and the effects of polishing pad material and its condition, pressure, rotating speed of the polishing plate, the type and size of abrasive, and the properties of the polishing slurry on the surface routhness and material removal rate were analysed in details
通過對鉭酸鋰晶片的化學機械拋光過程的實驗研究，通過測量鉭酸鋰晶片在不同拋光條件下的表面粗糙度和材料去除率，詳細分析了拋光墊材料和狀態、拋光壓力、拋光盤轉速、磨料種類及粒度、拋光液組成等幾個因素對拋光表面質量和材料去除率的影響規律。In the design, we adopt the microsoft windows 2000 advance server operating system and the system design that combines the server cluster and the san. nlb technology is used to realize the load balance of all the nodes in the server, and the layout of streaming media data preserved on the disk arrays is realized by coarse - grained striping. windows media technology is introduced to help the application of streaming media
在此設計中採用了服務器集群與存儲區域網路（ san ）相結合的系統設計，採用microsoftwindows2000advanceserver操作系統，利用網路負載平衡技術（ nlb ）實現服務器集群內各節點的負載均衡，採用粗粒度數據條紋化對磁盤陣列上存儲的流媒體數據進行布局，並使用windowsmedia技術實現流媒體應用。Zhang liji ( material physics and chemistry ) directed by professor xie xiaoming this paper is intended to solve problems for those who are designing, using pbgas. failure mechanism, as well as cycles to failure of two groups of pbga samples ( with / without underfill ) for thermal cycling conditions in the range of - 40 ~ 125, were presented. the experiment shows that solder ball in the samples without underfill cracked after 500 times cycle, no crack was found in the underfilled samples even after 2700 cycles
通過一系列的實驗，得到以下實驗結果： ?在本論文設定的溫度循環條件下，未充膠pbga樣品的熱疲勞品壽命在500周左右，充膠樣品的焊點壽命高於2700周； ?對于未充膠器件，中心距（ dnp ）是決定焊點應力、應變大小的最主要因素，裂紋總是從中心距較大處萌生並向中心處擴展； ?溫度循環的過程中焊盤附近焊料組織明顯粗化。分享友人
