joint aging time

joint aging time 双语例句

  1. We used infrared ray to exam the sample failure in the Al trace or solder bump after electromigration test. Because thick-film UBM has Kelvin probes structure, we also used 4-point probe to measure bump resistance in thick-film bump. Before bump open, we found different failure mechanisms between aging-free and aging solder joint. Sample which age may form IMC bridge between chip and board during electromigration test. It may be an important reason to prolong the sample life time.
    我们发现不同的破坏机制在有热时效与没有热时效在试片整个损坏前,由於厚膜试片有著Kelvin probes结构,所以我们可以使用四点量测去测量试片中因为电迁移孔洞造成焊锡球电阻增加情形,观察其中的破坏机制,我们发现热时效过后的试片,在电迁移测试中容易产生IMC桥连接晶片端与基版端使电子通过,可能也是增加试片life time的重要因素之一。
