Solder ball landpad design to improve laminate performance |
| 摘要 |
A method and apparatus for improving the laminate performance of the solder balls in a BGA package. Specifically, the ball pads on the substrate are configured to increase the shear force necessary to cause delamination of the solder balls. Conductive traces extending planarly from the pads and arranged in specified configurations will increase the shear strength of the pad.
