 our Package on Package (“PoP”) technology through the development of ultra-thin substrates and enhancing our pre-stacking and thin die handling capabilities.

We developed fine pitch copper pillar flip chip interconnect technology, which creates interconnections at finer pitches using a plating process to reduce the number of substrate layers to facilitate very thin packages.  This innovative solution is also an enabling technology for package stacking with TSVs.

FCBGA Products:  FCBGA packages are large form factor substrate-based packages which are used where processing power and speed are a higher priority than a small form factor.  Our FCBGA packages are assembled using state-of-the-art substrates.  Utilizing multiple high density routing layers, laser drilled vias, and ultra-fine line and space metallization, FCBGA substrates have the highest routing density available.  The variety of FCBGA package options, from large single die to multi-chip packages with memory, allows package selection to be tailored to the specific thermal needs of the end product.  We offer FCBGA packaging in a variety of product formats to fit a wide range of end application requirements, including networking, storage, computing, automotive and consumer applications.  Some FCBGA products incorporate 2.5D technology, which utilizes high density silicon interposers to enable the integration of high-performance chips, such as high bandwidth memory and graphics processors, into a single package. 

Memory Products: Memory packages consist of either standalone packaging and testing or a combination of NAND Flash, DRAM, or a memory controller IC using a variety of packaging technologies, including FC, SCSP, SiP, PoP and

other state-of-the-art packaging technologies.  These products are used as system memory or platform data storage in all of our end markets.  

Wafer-level Package Products:  We offer three types of wafer-level packages: wafer-level CSP; WLFO; SiPh and CPO; and SWIFT.  Wafer-level CSP and WLFO are complementary technologies.  Customers can choose between the two package types as their die sizes shrink or grow.

•Wafer-level CSP packages (also known as fan-in wafer-level packages) do not utilize a package carrier.  The bumped wafer is singulated into individual die, and the wafer-level package is then attached directly to the system board.  Wafer-level CSP offers one of the lowest total system costs, enabling higher semiconductor content while leveraging the smallest form factor and one of the highest performing
