Latest Patents
Jayshree Shah holds a patent for a "Flip-chip assembly with organic chip carrier having mushroom-plated solder resist opening." This invention discloses embodiments of a flip-chip assembly and method using lead-free solder. The assembly incorporates mushroom-plated metal layers that fill and overflow solder resist openings on an organic laminate substrate. The lower portion of the metal layer provides structural support to its corresponding solder resist opening. The upper portion, or cap, of each metal layer serves as a landing spot for a solder joint between an integrated circuit device and the substrate, allowing for enhanced solder volume control. This additional structural support, combined with improved solder volume control, minimizes strain on the resulting solder joints. Furthermore, the cap allows the minimum diameter of the solder joint on the substrate side of the assembly to be larger than the diameter of the solder resist opening. Thus, the invention decouples C4 reliability concerns from laminate design concerns, allowing for greater design flexibility.
