FCCSP Technology

Technology Overview

Flip Chip interconnection, also knownas Controlled Collapse Chip Connection, C4, Chip Connection, C2, has been identified as a high performance packaging solution to meet the growing need for products with increased electrical performance, high I/O, and high system reliability as a replacement for conventional wire bond packaging technology. Utilizing whole die area for electrical connection, substrate I/O per unit increases exponentially compared to perimeter wire interconnection technology.

Flip chip interconnect also allows direct connection with on-die power planes which enables increased electrical performance including increased switching speed and more efficient power distribution to the IC performance at lower operating voltages.

Applications

Flip Chippackage technology is considered one of the most established technologyfor high pin count and/or high performance. FC CSP provide package solution for Smartphones, Networking/Connectivitydevices.
