Abstract:
1. A wafer-level packaged device comprising: an integrated circuit chip; a resilient lead disposed on the integrated circuit chip, the resilient lead comprising an elongated lead member having a first end pivotally coupled to the integrated circuit chip and a second end configured to rotate about the first end to contact a pad formed on the printed circuit board, the first end having a first μbump and the second end having a second μbump, the resilient lead configured to move from a first position wherein the resilient lead is held adjacent to the integrated circuit chip to a second position wherein the resilient lead is extended away from the integrated circuit chip during an assembly reflow process to interconnect the integrated circuit chip to a printed circuit board; and a guard disposed on the integrated circuit chip, the guard configured to protect the resilient lead when the resilient lead is in the first position.
