Novel Molded FCBGA Package Platform For Highly Reliable Automotive Applications

By InRak Kim - 19 Sep, 2024 - Comments: 0

The conventional flip chip ball grid array (FCBGA) package platform has wide industry usage and provides high electrical performance. However, as high performance requirements increased, it encounters significant challenges. FCBGA packages frequently encounter underfill cracks after long term reliability or harsh reliability test conditions for automotive devices. Figure 1 shows the typical und... » read more

Simultaneous Bi-Directional Signaling: A Breakthrough Alternative For Multi-Die Assemblies

By Ramin Farjadrad - 29 Aug, 2024 - Comments: 0

In designing multi-die systems-in-package, with or without chiplets, it is easy to think of the interconnect between dies as simply analogous to the interconnect between functional blocks on a single die. But this analogy can lead architects and designers into a blind alley from which it becomes impossible to meet system performance and power requirements. The reason lies in fundamental differe... » read more

Current Characterization Of Various Cu RDL Designs In Wafer Level Packages (WLP)

By JeongMin Ju - 15 Aug, 2024 - Comments: 0

Copper (Cu) redistribution layer (RDL) technology is used to interconnect chips in various high current Wafer Level Packaging (WLP) applications. Typically, Cu RDLs with thicknesses of 5-9 µm and widths of 5-20 µm are used for high current sourcing. In this case, the temperature of the Cu RDL metal line increases due to the Joule heat generated when current passes through the metal line. If a... » read more

Five Questions To Ask When Selecting A Temporary Bonding And Debonding System

By Jessica Albright - 15 Aug, 2024 - Comments: 0

High-bandwidth memory blocks (HBM), microprocessors, field-programmable gate arrays (FPGA), AI accelerators, and other devices used in advanced system-level packaging all rely on temporary bonding and debonding systems to shrink their footprint. Understanding which properties play the most crucial role in device reliability and efficient production will ensure you are maximizing your yield, whi... » read more

Here At Last! Automated Verification Of Heterogeneous 2D/3D Package Connectivity

By Michael Walsh - 25 Jul, 2024 - Comments: 0

By Michael Walsh and Jin Hou with Todd Burkholder The heterogeneous integration of multiple ICs in a single package along with high-performance, high-bandwidth memory is critical for many high-performance computing applications. After everything has been heterogeneously integrated and packaged, such designs feature complex connectivity with many hundreds of thousands of connections, making i... » read more
