Wikipedia / IPC (electronics)

IPC is a global trade association whose aim is to standardize the assembly and production requirements of electronic equipment and assemblies. IPC is headquartered in Bannockburn, Illinois, United States with additional offices in Washington, D.C. Atlanta, Ga., and Miami, Fla. in the United States, and overseas offices in China, Japan, Thailand, India, Germany, and Belgium.

IPC is accredited by the American National Standards Institute (ANSI) as a standards developing organization and is known globally for its standards. It publishes the most widely used acceptability standards in the electronics industry.

History

It was founded in 1957 as the Institute of Printed Circuits. Its name was later changed to the Institute for Interconnecting and Packaging Electronic Circuits to highlight the expansion from bare boards to packaging and electronic assemblies. In 1999, the organization formally changed its name to IPC with the accompanying tagline, Association Connecting Electronics Industries.

Standards

IPC standards are used by the electronics manufacturing industry. IPC-A-610, Acceptability of Electronic Assemblies, is used worldwide by original equipment manufacturers and EMS companies. There are more than 3600 trainers worldwide who are certified to train and test on the standard. Standards are created by committees of industry volunteers. Task groups have been formed in China, the United States, and Denmark.

Market research

IPC members are eligible to participate in IPC’s statistical programs, which provide free monthly or quarterly reports for specific industry and product markets. Statistical programs cover the electronics manufacturing services (EMS), printed circuit board (PCB), laminate, process consumables, solder and assembly equipment segments.

Annual reports are distributed for the EMS and PCB segments, covering market size and sales growth, with breakdowns by product type and product mix as well as revenue trends from value-added services, trends in materials, financial metrics, and forecasts for total production in the Americas and the world.

Monthly market reports for the EMS and PCB segments provide recent data on market size, sales and order growth, book-to-bill ratios and near-term forecasts.

Classes

The IPC have established three classes of workmanship standards for assemblies, IPC Class 1, IPC Class 2, and IPC Class 3.

Usually both Class 1 and Class 2 focus on consumer clients and Class 3 is for industrial use.
