- Update the latest research and developments on electronic hardware corrosion and creep corrosion
- Share knowledge and experience, better understand the threshold to corrosion/creep corrosion
- Reach common understanding and consensus on corrosion challenges and appropriate operating environment for mission critical electronic equipment
Data & telecom center customers and suppliers, researchers on metal corrosion
Electronic hardware can be susceptible to corrosion or even creep corrosion in corrosive environments. Creep corrosion is the corrosion of metallization (generally copper and silver) and the migration of the corrosion product (typically copper and silver sulfides) across the printed circuit board (FR-4 and solder mask) surfaces. In environments high in sulfur-bearing gaseous contamination, the extent of creep corrosion may be so high as to electrically short circuit adjacent pads and traces, causing the circuit boards to malfunction.
To help eliminate creep corrosion, industry has initiated significant efforts to better understand its cause and mitigation, including technical groups from ASHRAE, IPC, ISA and iNEMI. CDCC has been concerning the IT equipment corrosion under the operating environment of the data centers in China and conducted survey to investigate the status.
iNEMI had an experimental program using mixed-flowing gases (MFG) test studying the creep corrosion during 2009-2012, which compared the sensitivity of various surface finishes and fluxes to corrosion. Then from 2013 iNEMI launched a study using flower of sulfur (FoS) test for creep corrosion. The goal is to provide the industry a simple and proven test to qualify PCB technologies.
In 2012, CDCC organized a workshop in Beijing discussing corrosion challenges to data center equipment when operating in a corrosive environment. The effect of relative humidity to corrosion was questioned at the workshop. We expect in this 2017 workshop that some of the questions can be answered, and the stakeholders of data and telecom centers would have a better understanding of corrosion issue and future challenges.
The International Electronics Manufacturing Initiative is an industry-led consortium is made up of approximately 90 manufacturers, suppliers, industry associations and consortia, government agencies and universities. Its mission is to forecast and accelerate improvements in the electronics manufacturing industry for a sustainable future. iNEMI roadmaps the needs of the electronics industry, identifies gaps in the technology infrastructure, establishes implementation projects to eliminate these gaps (both business and technical), and stimulates standards activities to speed the introduction of new technologies. The consortium also works with government agencies, universities and other funding agencies to set priorities for future industry needs and R&D initiatives. iNEMI is based in Herndon, Virginia (near Washington, D.C.), with regional offices in China, Ireland, UK and Japan.

China Data Center Committee (CDCC) is a standards and technology organization formed to promote national standards, develop technical white papers, conduct research on today's important topics while offering project consulting, market research and other related services, which serves the ultimate mission of increasing the level of standardization and generally promoting the overall progress of the data center market and technology.
The China Data Center Committee was established in March 2009. By adhering to the goal of promoting the progress of standardization in the China data center industry, by means of the development of industrial technical standards, relying on writing members and senior experts as a foundation, leveraging the powerful platform of standards and technology organization, gathering the wisdom of technical professionals from data center engineering and construction firms, as well as from product manufacturers; the China Data Center Committee is determined to elevate the overall level of engineering and construction of the China data center industry.
