ユーロフィンFQL Company Overview

In connectors that connect various hardware such as automobiles, industrial equipment, and communication devices, low-cost Sn-plated products are widely used. However, there are also cases where attention is needed regarding the reliability specific to Sn-plated contacts. In this webinar, based on actual connector failure cases that have occurred in the market, we will explain the process leading to the identification of causes for typical failure modes such as: - Whiskers (short circuit failures) - Fretting wear (contact failures) Furthermore, we will systematically introduce the organization of failures through the FTA (Fault Tree Analysis) of the entire connector, as well as each failure mechanism. ■ Technical content to be explained: - FTA structure of connector failures - Mechanism of whisker formation and evaluation methods - Mechanism of fretting wear and evaluation methods ■ Introduction of future evaluation technologies: - High-temperature and high-humidity fretting wear testing (scheduled for introduction in December 2026)

Rechargeable lithium-ion batteries that can be used repeatedly. They are used in a wide range of fields, from small consumer products to IoT devices, industrial equipment, and, in recent years, various mobility products. On the other hand, accidents caused by smoke and fire from lithium-ion batteries used in various environments are increasing year by year. Why do smoke and fire accidents persist? One reason is that the risks of smoke and fire have not been thoroughly examined. Eurofins FQL has been evaluating and analyzing battery cells and packs provided by numerous domestic and overseas suppliers for many years since the proliferation of lithium-ion batteries. In this seminar, we will introduce the reliability, safety evaluation, and analysis methods of lithium-ion battery cells and protection circuits using case studies.

Unstoppable battery fires. Chaos from semiconductor supply shortages. How can we identify poor-quality products and prevent recalls? Poor-quality products are not limited to batteries frequently covered by the media, but also include OEM products, semiconductors that are in short supply, and a wide range of connectors and cables that users prioritize for appearance and price. Suppliers of products need to thoroughly evaluate the components and materials used in their products to ensure quality. However, it is common for manufacturers to change parts and usage without notice, leading to defective products entering the market unnoticed, which can trigger product accidents. Key points to prevent recalls include: - Product evaluation and safety assessment at the time of adoption - Confirmation of supplier quality assurance systems at the time of adoption - Verification of sales through legitimate domestic channels - Regular checks for silent changes Eurofins FQL has been involved in product quality assurance for a long time. Leveraging that expertise, we offer services for safety evaluations of batteries, identification of poor-quality products, and factory audits from the perspective of managing upstream quality.
