Failure analysis of electronic devices and components

The spread of 5G communication, the electrification of the automotive industry, the intensification of US-China trade friction represented by certain semiconductor manufacturers leading to supply stoppages, and the rapid increase in digital products due to the impact of the COVID-19 pandemic are various social phenomena that are increasing the demand for semiconductors. Along with these developments, the acceleration of semiconductor supply risks is progressing. In addition to the adoption of new products, evaluation of existing and distributed products is also necessary... However, the personnel involved in new adoption and product evaluation are limited. Do you have any of these concerns? - Lack of know-how to evaluate semiconductor components - Want to evaluate alternative products but lack personnel and equipment - Want to use stock items and market products but have concerns about reliability - Unable to determine whether the delivered semiconductor products are counterfeit or genuine At Eurofins FQL, we leverage our years of experience in component evaluation and failure analysis to provide not only semiconductor evaluations but also failure analysis services. Additionally, we offer evaluations of distributed products to assist in determining the authenticity of counterfeit, imitation, or long-term stored items. Please feel free to contact us.

The usage environment of electronic devices varies, and the impact of corrosion caused by various environmental factors tends to increase. The reliability and lifespan of electronic devices heavily depend on the environment in which they are used. Corrosive substances originating from hot springs, volcanoes, waste, and rivers can corrode electronic components, printed circuit board wiring, connector contacts, and switch contacts of electrical equipment, potentially leading to serious issues. This content is recommended for those who want to solve such challenges: • Does the atmosphere of the operating environment lead to failures in electronic devices? • I want to reduce the risk of failure in harsh environments such as hot springs and wastewater treatment plants. • I want to conduct environmental surveys in large factories with fewer personnel and man-hours. • I want to prolong the lifespan of aging infrastructure as much as possible. We will introduce our original corrosion environment diagnostic kit, Eco Checker II, as well as methods for diagnosing corrosion environments.

We will be exhibiting at the 54th Reliability, Maintainability, and Safety Symposium. ■Content We will present a case study focusing on market failures that resulted from contact failure due to corrosion (dezincification) occurring inside pogo pins. Additionally, we conducted verification on new samples based on four key points extracted from FTA (corrosive substances, temperature/humidity, scratches (wear), and pinholes), and found that the presence of formate ions and sulfate ions, along with scratches (wear), significantly accelerated corrosion. We will estimate the contact failure mechanism derived from the verification results.

The spread of DX (Digital Transformation) has led to an increase in electronic devices and equipment across various fields. As DX progresses, the opportunities for these devices to be used in diverse environments are increasing, and quality issues due to corrosion are becoming a significant challenge. The digitization of business processes in factories, infrastructure, agriculture, and healthcare is expanding the installation of electronic devices such as IoT sensors, edge devices, and network equipment. These devices are often placed not only in ideal indoor environments but also in harsh conditions, which amplifies the impact of corrosion. In this seminar, we will provide a concrete explanation using examples of evaluation, analysis, and countermeasures against troubles caused by corrosion. This is recommended for those facing the following quality issues: - Connection failures and short circuits - Deterioration of electronic devices - Shortened product lifespan - Corrosion prevention measures
