Fine-pitch Copper Pillar Flip Chips in High Reliability Applications

Abstract To keep up with the demands for smaller antennas with increased performance and decreased costs, most next generation architectures mandate higher IC (integrated circuit) chip integration. Compared to conventional packaging configurations, advanced chip packaging technologies, such as 2.5D and 3D, offer greater chip compatibility and lower power consumption. Given these advantages, the adoption of advanced packaging is inevitable. Within advanced packaging, the copper pillar interconnect is a key enabling technology, and the next logical step. This technology offers several benefits, including improved electromigration resistance, improved electrical and thermal conductivity, simplified underbump metallization (UBM), and higher I/O (input/output) density. The fine pitches that copper pillars allow helps the technology to supersede solder bump technology, which reaches its lowest pitch around 40 microns. Finer pitches allow for a higher I/O count, which increases performance. In this work, assembly of ultra-thin MMIC (monolithic microwave integrated circuit) GaN (Gallium Nitride) fine-pitch copper pillar flip chip assemblies on high density interposers was successfully demonstrated. Using 150μm pitch copper pillar flip chip, the assembly processes for both organic PCB (printed circuit board) and silicon interposers were evaluated, with both an ENIG (Electroless Nickel Immersion Gold) and eutectic tin-lead solder pad finish evaluated. For the 2D/2.5D/3D assembly process development, a standard in-house pick and place tool was used, followed by mass solder reflow, finished with an underfill for reliability test. The interconnect robustness was determined by die pull strengths, a flux stamping investigation, and cross-sections. Complete reliability and qualification test data on GaN copper pillar flip chip 2D assembly was completed, including 700 temperature cycles and UHAST (unbiased highly accelerated temperature/humidity stress test).

Gaps in Live Inter-Observer Reliability Testing of Animal Behavior: A Retrospective Analysis and Path Forward

Observational behavior research is an important activity for zoos and aquariums, often being conducted to provide insights into welfare and guide management decisions. This research relies on standardized protocols to ensure consistent data collection. Inter-observer reliability, where untrained observers are tested against the behavior identifications of an expert observer, represent a critical internal validation process. Recent software advances have made reliability testing easier and more accessible, but there is limited guidance on what constitutes a strong reliability test. In this study, we reviewed historic reliability test data from Lincoln Park Zoo’s on-going behavior monitoring program. Six representative species were chosen that included 645 live pairwise reliability tests conducted across 163 total project observers. We identified that observers were being tested on only approximately 25% of the behaviors listed and defined in the species ethograms. Observers did encounter a greater percent of the ethogram with successive reliability tests, but this gap remained large. While inactive behaviors were well-represented during reliability tests, social and other non-maintenance solitary behaviors (e.g., exploratory, scent marking, play, etc.) did not frequently occur during tests. While the ultimate implications of these gaps in testing are unclear, these results highlight the risks of live reliability testing as an inherently non-standardized process. We suggest several approaches to help address these limitations, including refining ethograms, reconsidering criteria, and supplementing live training with video. We hope this self-critique encourages others to critically examine their methods, enhance the quality of their behavioral data, and ultimately, strengthen conclusions drawn about animal behavior and welfare.

Field‐scale apparent soil electrical conductivity

AbstractSoils are notoriously spatially heterogeneous and many soil properties are temporally variable. Spatial variability of soil properties has a profound influence on agricultural and environmental processes, such as plant–water–soil interactions, water flow, and solute transport, resulting in within‐field plant yield variation and degradation of soil quality, to mention only a few. Field‐scale mapping of spatial variability and monitoring of temporally dynamic soil properties is necessary for a variety of edaphic activities, such as soil surveys, reclamation, crop selection, sitespecific management, and soil quality assessment. There are various approaches for characterizing soil spatial variability, but none of these has been as extensively investigated and is as reliable and cost effective as apparent soil electrical conductivity (ECa) directed soil sampling. Geospatial measurements of ECa are well suited for characterizing the spatial distribution of soil properties because they are reliable, quick, and easy to take with GPS‐based mobilized ECa measurement equipment. Directed soil sampling based on geo‐referenced measurements of ECa is a proven and robust means of characterizing the spatial variability of any soil property that influences ECa, including sol salinity, water content, texture, bulk density, organic matter, and cation exchange capacity. It is the goal of this methodology paper to provide an overview of the characterization of soil spatial variability across multiple scales using ECa–directed soil sampling with a focus on the field scale. Mobile ECa equipment, protocols, guidelines, special considerations, data reliability tests, and strengths and limitations are presented for characterizing spatial and temporal variation in soil properties using ECa–directed soil sampling.
