Package on Package (PoP) Stacking and Board Level Reliability, Results of Joint Industry Study

Technical Library | 2007-08-02 13:24:23.0

This paper presents the results of a joint - three way study between Amkor Technology, Panasonic Factory Solutions and Spansion in the area of package on package (PoP) board level reliability (BLR) (...) The scope of this paper is to cover the already popular 14 x 14mm PoP package size that provides a 152 pin stacked interface which supports a high level of flexibility in the memory architecture for multimedia requirements.

2.5D and 3D Semiconductor Package Technology: Evolution and Innovation

Technical Library | 2017-09-14 01:21:52.0

The electronics industry is experiencing a renaissance in semiconductor package technology. A growing number of innovative 3D package assembly methodologies have evolved to enable the electronics industry to maximize their products functionality. By integrating multiple die elements within a single package outline, product boards can be made significantly smaller than their forerunners and the shorter interconnect resulting from this effort has contributed to improving both electrical performance and functional capability. (...) This paper outlines both positive and negative aspects of current 3D package innovations and addresses the challenges facing adopters of silicon and glass based interposer fabrication. The material presented will also reference 3D packaging standards and recognize innovative technologies from a number of industry sources, roadmaps and market forecasts.

High Frequency Dk and Df Test Methods Comparison High Density Packaging User Group (HDP) Project

Technical Library | 2019-02-06 22:02:08.0

The High Density Packaging (HDP) user group has completed a project to evaluate the majority of viable Dk (Dielectric Constant)/Df (Dissipation Factor) and delay/loss electrical test methods, with a focus on the methods used for speeds above 2 GHz. A comparison of test methods from 1 to 2 GHz through to higher test frequencies was desired, testing a variety of laminate materials (standard volume production with UL approval, low loss, and "halogen-free" laminate materials). Variations in the test board material resin content/construction and copper foil surface roughness/type were minimized. Problems with Dk/Df and loss test methods and discrepancies in results are identified, as well as possible correlations or relationships among these higher speed test methods.
