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.
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.
The IPC preferred term for an assembled board is circuit card assembly (CCA), [20] and for an assembled backplane it is backplane assembly. "Card" is another widely used informal term for a "printed circuit assembly". For example, expansion card. A PCB may be printed with a legend identifying the components, test points, or identifying
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 ...
These failures result from the thermomechanical stresses caused by coefficient of thermal expansion (CTE) mismatch, in the PCB thickness direction, between the metallization in a microvia structure and the dielectric materials surrounding the metal. The following paragraph highlights some of the microvia reliability research.
Bare die supplied without a package. It is mounted directly to the PCB using bonding wires and covered with a blob of black Epoxy. [22] Also used for LEDs. In LEDs, transparent epoxy or a silicon caulk-like material that may contain a phosphor is poured into a mold containing the LED(s) and cured. The mold forms part of the package. COF: Chip ...
IPC (electronics), an international trade association for the printed-board and electronics assembly industries; IPC Healthcare, US healthcare corporation; Imperial Privy Council, another name for the Privy Council of the United Kingdom; IPC Systems, a firm providing communication systems for financial markets
Solder paste is used in the manufacture of printed circuit boards to connect surface mount components to pads on the board. It is also possible to solder through-hole pin in paste components by printing solder paste in and over the holes. The sticky paste temporarily holds components in place; the board is then heated, melting the paste and ...
