摘要:
Disclosed are devices, fabrication methods and design rules for flip-chip devices. Aspects include an apparatus including a flip-chip device. The flip-chip device including a die having a plurality of under bump metallizations (UBMs). A package substrate having a plurality of bond pads is also included. A plurality of solder joints coupling the die to the package substrate. The plurality of solder joints are formed from a plurality of solder bumps plated on the plurality of UBMs, where the plurality of solder bumps are directly connected to the plurality of bond pads.
