没什么联系,die bond是焊片,将芯片焊接到框架上,wire bond是焊线,在已经焊好芯片的框架上,连接芯片上的焊盘和框架的管脚。bond pad 就是焊盘。die bond工艺 在wire bond工艺前面,具体的原理和工艺就比较复杂了,现在die bond 有共金热压焊和银胶焊,还有薄膜焊,wire bond有金线,铜线,铝线焊...
Reliability data verifies the effectiveness of the design principles. Proper design of interconnects beneath the pad can greatly increase pad robustness to cracking, allowing much more margin in bonding stress, enabling the option of Au or Cu wire bond on the same IC without pad cracking. 展开 ...
