Abstract :
The application of a controlled-collapse-chip-connection, ceramic-ball-grid-array (C4/CBGA) module for a RISC microprocessor is presented. The zero to second-level interconnection technologies and the various design considerations, from the on-chip redistribution metal to the single-chip module printed-circuit-board connection, are analysed. In addition to an overview of the interconnect technology, we discuss the: 1) electrical modeling and characterization, 2) board design and routability, 3) thermal management, and 4) C4 and ball-grid-array interconnection reliability
