FUKUDA CO., LTD. Product Lineup

In recent years, the environment surrounding the manufacturing sites of food and pharmaceuticals has changed significantly. Consumers' scrutiny of food safety and quality has become stricter than ever, and in the event of a product accident (such as food poisoning) caused by "seal defects" or "pinholes," it could lead directly to a large-scale recall and a loss of brand trust. If this involves a core product, it could jeopardize the company's survival. (From July 2021 to June 2025, there were 15 cases of voluntary recalls due to packaging defects.) On the other hand, the labor shortage supporting these sites has become increasingly severe, making it increasingly difficult to maintain a quality control system that relies on the skills and intuition of experienced workers. 1. The dilemma of "risk and cost" faced by manufacturing and quality assurance sites Is your manufacturing and quality assurance site also facing a serious dilemma regarding "quality control and on-site costs"? *Please be sure to check the continuation of the column from the "related links."

1. Accidents Caused by Leaks in Secondary Batteries Recently, with the widespread use of secondary batteries, including lithium-ion batteries, related accidents have been reported one after another. There have been serious incidents such as mobile batteries igniting inside trains, batteries of electric assist bicycles exploding while parked, and large-scale fires destroying multiple electric motorcycles during charging. One of the main causes of these accidents is "leakage." Even minor defects can pose a risk of leading to serious accidents after the product is commercialized or used in the market. Proper leak detection in secondary batteries is essential to prevent market accidents and ensure product reliability. 2. Why Are Leaks in Secondary Batteries Dangerous? * Please check the "Related Links" for the continuation of this column.

The explosive proliferation of generative AI and the expansion of advanced cloud infrastructure are bringing about a significant turning point in the thermal design of data centers. To support a digital society that operates 24/7, cooling technology is evolving from air cooling to water and liquid cooling; however, this evolution also hides new structural risks. Threats that jeopardize mission-critical systems—focusing on the "microscopic leaks of cooling water" in next-generation data centers, which could significantly impact the digital society, we propose specific approaches for early detection and identification. 1. The reason why "comprehensive quality assurance" is required The liquid cooling systems in data centers consist of countless components. "Cold plates" that absorb heat within servers, "manifolds" that branch the flow paths, "cooling pipes" that extend for kilometers, and "quick connectors" that link them together. Leaks are not permissible at these joints. Moreover, the stakeholders involved in the lifecycle of liquid cooling equipment are diverse, and each must ensure quality within their different areas of responsibility (phases). *Please check the "related links" for the continuation of this column.

1. What is "leak" that affects the quality of electronic components? With the spread of IoT, the electrification of vehicles, and the enhancement of industrial equipment's functionality and precision, electrical and electronic components are now required to meet stricter quality standards than ever before. At the core of ensuring the long-term reliability of products is "hermetic sealing," which is performed using materials such as metals, solder, and glass. If defective products with "leaks" in their packaging are released into the market, they can lead to serious nonconformities (failure modes) such as the following, resulting in troubles that undermine the company's credibility: - Short circuits or corrosion of internal circuits due to moisture intrusion - Decreased functionality due to gas leakage - Insulation breakdown caused by deterioration of the internal environment - Deterioration of characteristics and shortened lifespan due to accelerated aging Our company provides high-precision leak testing that can instantly detect minute defects on the production line (inline) that traditional visual inspections and continuity tests cannot identify. * Please be sure to check the continuation of the column from the "Related Links."
