ELIMINATING DIE SHADOW EFFECTS BY DUMMY DIE BEAMS FOR SOLDER JOINT RELIABILITY IMPROVEMENT

机译:消除虚拟模具梁的模具阴影影响,提高焊接接头的可靠性

摘要

A package with improved solder joint reliability is disclosed. The package includes dummy beams with less rigidity and stiffness (relative to the die) that are placed in between the die and the substrate. The reduced rigidity and stiffness of the dummy beams significantly mitigates any die shadow effects on the solder joints. Also, because the die is attached to the dummy beams and does not directly contact the substrate itself, the die shadow effect from a rigid die is further reduced.
