Whisker Development from SAC0307-Mn07 Solder Alloy [PDF]

, 2020
In this study, the whisker growth from SAC0307-Mn07 solder alloy was investigated. To get fast information, an ultra-thin film was vacuum evaporated from the examined solder alloy onto Cu substrates.

Analyses of the Deformability and Chemistry of Non‐Metallic Inclusions in QT Steels With Increased Recycling‐Induced Tramp Element Content

steel research international, EarlyView.
This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.

Future of edge AI in biodiversity monitoring

Methods in Ecology and Evolution, EarlyView.
Abstract Many ecological decisions are slowed by the gap between collecting and analysing biodiversity information. Edge computing moves data processing closer to the sensor, with edge artificial intelligence (AI) using AI models for data processing and selective data transfer.

Accelerated testing methodology for lead-free solder interconnects

, 2005
The purpose of accelerated testing is to provoke the same failure in a product during the test as it occurs in the real world but in shorter time than in the application.

Solid-phase transient soldering method based on Au/Ni–W multilayer thin-film-modified copper-based structures

Heliyon
The copper crystal cone-shaped micro-nanostructure is used as the substrate, and the Ni–W alloy layer and Au nanolayer are plated sequentially. Instantaneous soldering with lead-free solder is realized under ultrasonic assistance at room temperature ...

Beyond the Individual: Multisite Population‐Level Consequences of Road Mortality on a Declining Mammal

Animal Conservation, EarlyView.
We used a comparative study design to quantify population densities, structure, survival, cause‐specific mortality and female productivity in four West‐European hedgehog (Erinaceus europaeus) populations, and to forecast the impact of road mortality on population viability.

Tin Sensitization in Belgium and the Netherlands: Complementary Findings From Two Independent Retrospective Studies

Contact Dermatitis, EarlyView.
In retrospective studies the prevalence of tin sensitization and its clinical relevance was evaluated in two groups: consecutive patients and patients suspected of metal allergies. The prevalence was higher than previously reported and relevance could be established for ~30%.

Gold and Nickel Release From Jeweller‐Purchased 10K and 14K Gold Earrings in Cysteine‐Modified Artificial Sweat

Contact Dermatitis, EarlyView.
Even expensive 10K and 14K gold earrings released measurable gold in cysteine‐modified artificial sweat, despite no detectable nickel. Surface gold content did not predict release, challenging assumptions that higher gold content means lower exposure. ABSTRACT Background Gold contact allergy is common, but its clinical relevance is often uncertain.
