摘要
利用自动焊线机、推拉力测试仪、扫描电镜等研究了烧球电流、烧球时间、超声功率和键合压力对Ag-5Au键合合金线FAB(Free Air Ball)特性及键合强度的影响。研究结果表明当烧球时间为750μs,烧球电流为2600 mA时FAB球形成椭圆形,烧球电流为2800 mA时FAB出现高尔夫球;烧球电流为2700 mA,烧球时间为700μs时FAB偏小,烧球时间为800μs时FAB偏大;当烧球时间为750μs烧球电流为2700 mA时FAB形貌良好。当超声功率为85 mW键合压力为65 g时造成焊盘的损坏;超声功率为50 mW键合压力为35 g时出现假焊;超声功率为60 mW键合压力为45 g时键合强度良好。
The effects of Electronic Flame Off current,Electronic Flame Off time,bond power and bond force on Free Air Ball morphology and bonding strength of Ag-5Au bonding alloy wire were studied by automatic wire bonder,strength tester and scanning electron microscope.The results show that when the Electronic Flame Off time is 750μs and the Electronic Flame Off current is 2600 mA,the FAB sphere becomes elliptical,and the Electronic Flame Off current is 2800 mA,the FAB sphere appears golf ball;when the Electronic Flame Off current is 2700 mA and the Electronic Flame Off time is 700μs,the FAB is smaller,and when the Electronic Flame Off time is 800μs,the FAB is larger.when the Electronic Flame Off time is 750μs and the Electronic Flame Off current is 2700 mA,the FAB in good sphere.When the bond power is 85 mW and the bond force is 65 g,the pad will be damaged;when the bond power is 50 mW and the bond force is 35 g,the false welding will occur.
