DESCRIPTION
Flip Chip Ball Grid Array packages (fcBGA) form a subgroup of the
Flip Chip package family. The fcBGA package is the main platform
in this sub-group, which also includes bare die, stiffener only and a
thermally enhanced version with one/two piece heat spreader or lid
(fcBGA-H), System-in-Package (fcBGA-SiP) versions and a package
subsystem meeting the standard BGA footprint that contains multiple
components within the same package (fcBGA-MPM). Options also
include configurations with thin core, Pb-free and copper column
bumps. STATS ChipPAC’s Flip Chip BGA packages are available in ball
counts ranging from 220 to 3000+, body sizes from 12 x 12mm to
55 x 55mm.
STATS ChipPAC offers a complete fcBGA portfolio for the network,
computing and consumer markets. Demand for greater functionality
and significantly higher processing speeds in consumer and networking
devices is driving flip chip technology to provide cost effective, scalable
packages with ultra low K dielectrics, high power integrity, superior
thermal performance and higher resistance to electromigration (EM) in
very large package sizes, with very fine bump pitches and lead-free solder.
Flip Chip interconnection provides the ultimate in miniaturization,
reduced package parasitics and enables new paradigms in the area
of power and ground distribution to the chip not feasible with other
traditional packaging approaches. STATS ChipPAC offers full turnkey
services ranging from design through production, including high speed,
high pin count digital and RF testing.
