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.
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 ...
A standard-sized 8-pin dual in-line package (DIP) containing a 555 IC. Integrated circuits and certain other electronic components are put into protective packages to allow easy handling and assembly onto printed circuit boards and to protect the devices from damage. A very large number of package types exist.
1A1A44J5 - Unit 1, Assembly 1, Sub-Assembly 44, Jack 5 (J5 is a connector on a box referenced as A44) 1A1A45J333 - Unit 1, Assembly 1, Sub-Assembly 45, Jack 333 (J333 is a connector on a box referenced as A45) A cable connecting these two might be: 1A1W35 - In the assembly A1 is a cable called W35. Connectors on this cable would be designated:
A majority of the defects in circuit-board assembly are caused due to issues in the solder-paste printing process or due to defects in the solder paste. There are many different types of defects possible, e.g. too much solder, or the solder melts and connects too many wires (bridging), resulting in a short circuit.
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 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.
IPC-9071A [13] attempted to address this by focusing on 2nd level interconnects (i.e. package to PCB substrate). The challenge with this standard is that it has been more adopted by OEMs than component manufacturers, who tend to view it as an application-specific issue.
