IPC is a 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.
Hermes is a machine-to-machine communication standard used in the SMT assembly industry. [1]IPC-HERMES-9852. It is a successor to the SMEMA standard, introducing improvements such as: simpler physical wiring (Ethernet), use of popular data transmission formats (TCP/IP and XML), reduced number of barcode scanners (required only once at the beginning of the line), transmission of board data ...
The Wiring Harness Manufacturer's Association is a trade group for American manufacturers of wiring harnesses, electronic cable assemblies, and cord sets, along with their suppliers and distributors. [1] It publishes the widely used standard IPC/WHMA-A-620 Acceptability of Electronic Wire Harnesses and Cables jointly with IPC. [2]
The most common [citation needed] standards for conformal coating are IPC A-610 [9] and IPC-CC-830. [10] These standards list indications of good and bad coverage and describe various failure mechanisms, such as dewetting. Another type of coating called parylene is applied with a vacuum deposition process at ambient temperature. Film coatings ...
The IEEE 315 standard contains a list of Class Designation Letters to use for electrical and electronic assemblies. For example, the letter R is a reference prefix for the resistors of an assembly, C for capacitors, K for relays. Industrial electrical installations often use reference designators according to IEC 81346.
The IPC-NC-349 format is the only IPC standard governing drill and routing formats. [5] XNC is a strict subset of IPC-NC-349, Excellon a big superset. Many indefinite NC files pick some elements of the IPC standard. [1] A digital rights managed copy of the specification is available from the IPC website, for a fee.

In informal usage, the term "printed circuit board" most commonly means "printed circuit assembly" (with components). The IPC preferred term for an assembled board is circuit card assembly (CCA), [19] and for an assembled backplane it is backplane assembly. "Card" is another widely used informal term for a "printed circuit assembly".
