【Networking Power Supply】IPC-9592: The Key Reliability Standard of Networking Power Supplies NEW!

In today’s era, where AI is increasingly integrated into our everyday lives, high-speed internet and telecommunications systems play an essential role. The stability and reliability of power conversion devices behind these systems can directly impact the overall quality of network service. Any power failure can lead to service interruptions, data loss, or even more serious consequences.

To establish a unified and objective standard to ensure the quality and reliability of these key devices, 6 North American PCB manufacturers founded IPC (Institute of Printed Circuits) in 1957. IPC brought together various major players in the electronic manufacturing industry to develop common standards. In 2008, IPC released the first standard for power conversion devices for the computer and telecommunication industries: IPC-9592. The purpose of this standard does not focus on regulating the output specification of power supplies; instead, it emphasizes how to improve their reliability, durability and quality consistency. Therefore, IPC-9592 is a design guideline based on the “actual operating environment” and aims to fundamentally improve the reliability of power supplies.

IPC-9592B, the currently implemented version, primarily defines the requirements of the following aspects:

Design and reliability

Networking power supplies are usually exposed to environments with high temperatures and dense heat dissipation, long-term operation in data centers, and electromagnetic interference, among other factors. Therefore, these factors must be considered from the earliest stage of product design. IPC-9592B provides clear guidelines for addressing these requirements, including reliability prediction (MTBF/FIT), component derating, voltage spacing, MSL (moisture sensitivity level) management, corrosion protection, and more.

Design verification testing

To ensure power modules can operate smoothly over a long time period under harsh environments such as data centers and outdoor base stations, IPC-9592B specifies a series of various stress tests, including high-temperature/high-humidity and thermal cycling tests, vibration and shock testing, lifetime and durability tests, EMI/EMS testing, etc.

Process and quality consistency requirements

In addition to design considerations, IPC-9592B also addresses variation risks that may arise during mass production by specifying standardized requirements for traceability and random inspection throughout the entire process, from material receipt to manufacturing output, and from packaging to transportation, to ensure products from different lots maintain consistent electrical characteristics and reliability.

These rigorous specifications and requirements make IPC-9592B a common standard across networking systems and power supplies. Going beyond a mere technical document, IPC-9592B also represents industry-wide consensus on product reliability and quality commitment.

In APD, IPC-9592B is not an additional standard; it forms the natural foundation of our long-standing devotion to the networking power supply sector. From reliability control at the design stage to process consistency during mass production, APD has long integrated this standard into our daily development and production processes to ensure every lot of products operates stably and reliably under harsh environments.

APD consistently focuses on “Design reliability & manufacturing consistency”, providing trustworthy power solutions to customers as well as acting as the most reliable partner for networking system customers when building network equipment requiring high stability.
