Flip Chip Ball Grid Array (fcBGA or simply Flip-chip BGA) is a mid-cost, high-performance, semiconductor packaging solution that utilizes the controlled collapse chip connection technology, also known as flip chip, for its die to substrate interconnection. fcBGA provides the design flexibility for much higher signal density and functionality into a smaller die and packaging footprint. fcBGA packaging is attractive where performance is more important than cost. Flip-chip BGA packages can be mounted using standard printed circuit boards and can be replaced using existing standard repair practices.
Today most flip-chip BGA packages are assembled on two-metal layer or multi-layered, high density ceramic substrates or organic laminate. Additionally fcBGA packages are often offered in bare die, flat lid, and full lid configuration. They are used extensively ASIC, DSP, and various other high performance applications.
μFCBGA or micro-FCBGA is a line of fcBGA packages that ships with Intel's line of processors.
