of SnAgCu305 after electromigration 4.2 改善措施 4.2.1 微合金化 稀土元素Ce能够细化钎料组织,从而在焊点内部形成众多的大角晶界,抑制了电载荷作用下Cu和Sn的迁移,从而延缓了孔洞和裂纹的产生[74].已有研究表明[75],Sn基无铅钎料中Sn晶粒的取向能够显著影响焊点的抗电迁移性能,具有c取向的Sn晶粒具有更强的电迁移抗力.Co在Sn..., 92(21): 1335.

率达到93%,对,Cl-和等其他离子的吸附均小于1%.但活性炭材料易发生阴燃,缓慢氧化后有CO释放,在生产,贮存,运输过程中存在一定的安全隐患. 早在1970年,周长祥等[58]首次发现泡沫塑料可从卤化物中吸附金,铁,钼和铼等金属离子.周长祥等人使用聚氨酯聚醚型多孔泡沫塑料研究其在不同介质中对铼的吸附能力,结果表明在氢氟酸介质中对铜矿中铼的吸附率大于97%,富集倍数为 1×104.该吸附分离方法可......
