Latest Patents
One of his latest patents is a method to accommodate increase in volume expansion during solder reflow. This invention addresses the challenges faced by low melt C4 solder balls, which undergo volume expansion during reflow. When these solder balls are encapsulated, the expansion pressure can potentially damage the integrity of the device. Lehman's innovative approach includes creating a volume expansion region in the semiconductor chip substrate beneath each solder ball to accommodate this expansion. He also explores the use of air-cushioned diaphragms, deformable materials, and non-wettable surfaces to allow the solder to return to its original site during cooling. Additionally, a porous medium with sufficient voids to accommodate expansion is proposed.
