Background of New Service Development

In recent years, with the advancement of smart factory initiatives and automation in manufacturing sites, the importance of industrial network equipment designed for stable 24-hour operation has rapidly increased. Consequently, the global market for "PCB conformal coating (board coating)," which protects electronic circuit boards from environmental factors such as moisture and dust, is projected to expand steadily at an average annual growth rate (CAGR) of approximately 7.53% from 2026 to 2032, driven by the expansion of industrial automation (Source: QYResearch "PCB Conformal Coating - Global Market Share and Ranking, Total Sales and Demand Forecast, 2026-2032"). This technology is becoming a global standard for maintaining the reliability of electronic devices. Actual FA environments and social infrastructure installation sites are harsh environments for precision electronic equipment, characterized by condensation due to drastic seasonal temperature changes, fine dust, and oil mist. Diatrend has received many voices from field engineers and production technology staff expressing a desire to "reduce the risk of sudden line stoppages due to failures" and to "apply countermeasures in advance tailored to the installation environment." In response to these market needs and strong user demands, Diatrend has decided to launch this service as an option to easily enhance the environmental resistance and added value of equipment. Leveraging a flexible support system unique to a Japanese manufacturer, we will strongly back up "preventive maintenance" in Japan's manufacturing sites.

Features of the New Service

・Reduced possibility of troubles due to excellent insulating and moisture-proof film properties: This service uses a professional-grade dedicated board moisture-proofing agent with excellent insulation, moisture resistance, and rust prevention properties. By forming a protective film (PCB conformal coating) on the board surface, it reduces the possibility of troubles such as board shorts, leakage currents due to moisture, condensation, or conductive dust adhesion, and pattern disconnections caused by corrosive gases.

・Easily enhance added value with a "plus alpha" to standard products: Instead of undertaking large-scale equipment replacement or introducing specialized rugged models from scratch, you can reinforce environmental resistance as needed based on Diatrend's proven existing products.

・Meticulous processing with a reliable quality control system: Our technical staff will manually apply and dry the coating multiple times, forming a protective film down to the finest details. Diatrend, with its manufacturing and management system in Japan, delivers this with a reliable quality control system.

Future Outlook

Diatrend will continue to enhance solutions that support the stable operation of industrial network equipment, by staying close to the real challenges and user needs of Japanese manufacturing sites. Starting with the support for 26 models including industrial hubs, we plan to expand the lineup of target products in the future. We aim to foster a brand image of "Diatrend, which flexibly responds to the detailed needs of the site in Japan for industrial networks," and pursue further improvements in the added value of our products and services.

Notes on Use

This service is an optional service that can only be applied for when purchasing new target products (when ordering new). For products that have already been delivered or are in use, we cannot accept post-installation processing due to the need to clarify the scope of quality assurance and risk liability. Please understand this in advance.

Furthermore, this service is a preventive maintenance measure to reduce the possibility of board troubles caused by environmental factors, and it does not guarantee complete operation of the equipment or compensate for losses incurred by any line stoppages. It does not provide waterproofing (IP rating, etc.). Therefore, if you are considering use in environments where water is constantly splashed or in harsh environments where there is a risk of submersion, please be sure to select specialized rugged products such as "IP67 compliant products."

[Explanation: What is PCB Conformal Coating?]

This is a technology that protects electronic components from the surrounding environment (moisture, condensation, dust, chemicals, etc.) by covering the surface of a printed circuit board with a thin insulating film. It is widely used in fields requiring high reliability, such as the FA industry, automotive, and aerospace.

In various moisture resistance and insulation resistance tests simulating harsh high-humidity environments (e.g., 95% humidity or higher), it has been technically demonstrated that the risk of electrical leakage (short circuits) is significantly suppressed compared to uncoated boards. It is an extremely effective preventive maintenance technology for FA sites to further enhance the reliability of standard products and reduce the risk of sudden communication troubles caused by environmental factors.

● We also offer a variety of other industrial Ethernet switching hubs, including PoE-related products.
