I would like to carry out a survey of all the available flipchip bump metallurgies available with the compatible bond pad finishes and compatible substrate attachment methods. The results will be posted on this forum. Your input will be very much app

I saw the problem of void in solder bump or in lead less component or some BGA. But I didn't have standard specification of that void is accept or reject? Do any body have the better idea or suggestion of the criteria ? Thank you, Wirat S. / Jan 15

Our spec on voids is 30% ball diameter in the center. On the component to ball and pad to ball interface, we use 25%. To determine this spec, we asked around. I don't know of any studies that have been done to verify if this is OK Regards Jim |
