What is the meaning of IPC of component package in PCB

IPC is a standard for printed circuit boards.

IPC was originally "The Institute of Printed Circuit" abbreviation, that is, the United States "Printed Circuit Board Association", later renamed "The Institute of the Interconnecting and Packing Electronic Circuit" (Electronic Circuit Interconnecting and Packaging Association), in 1999 again changed its name to "Association Of Connecting Electronics Industries" (Electronics Manufacturing Association). Because IPC is so well known, the IPC logo and acronym remained unchanged after the name change. IPC has more than 2,600 members, including world-renowned organizations engaged in printed circuit board design, manufacturing, assembly, OEM (Original equipment manufacturer) processing, EMS (electronics manufacture service), and other related industries. Electronics Manufacturing Service) outsourcing of large companies, IPC and IEC, ISO, IEEE, JEDC, is the United States and the world's electronics manufacturing industry is one of the most influential organizations. IPC has developed thousands of standards and specifications, the following are commonly used in the electronics manufacturing industry, several standards and specifications:

Design standards:

IPC-D-275 rigid printed circuit boards and their connections to the design standards, according to the precision of the wiring, the density and complexity of the manufacturing process, the standard is divided into A, B, C three levels.

IPC-SM-782 Pad Graphics Standard for Surface Mount Design.

IPC-SM-770 Printed board component assembly specifications, including surface mount and through-hole mount design requirements.

Finished Product Design Documentation Specification:

IPC-D-325 is a documentation specification for customers to use when designing boards and proposing assembly requirements for their products, where the specifications can refer to the relevant industry standards or working standards, or they can use their own in-house standards as per customer preference.

Production site standards:

IPC-A-610 is a picture of the description of the document, describing the printed circuit boards of a variety of higher than the general requirements of the product mounted on the structural characteristics, describes the structural form of the components failed to help the production site personnel in a timely manner to detect and correct the problem.

The above listed standards, IPC-A-610 that is, "Acceptable of Electronic Assemblies" (translated as "Acceptable Conditions of Electronic Components") as the production of electronic assemblies at the site of the appearance of the quality of the visual inspection specifications, become the electronic manufacturing industry nowadays use the most extensive This standard has several versions. There are several versions of this standard, and the latest version, IPC-A-610C, was published in January 2000. Compared with the B version, the C version of the book has more than 600 color illustrations of the acceptability of the process standard pictures, these accurate, clear pictures strictly illustrate the process conditions associated with modern electronics assembly technology, including the electronic components ESD (Electrostatic Discharge that is, Electrostatic Discharge) protection of the operation, mechanical assembly, the direction of the component mounting, soldering, Marking, laminates, separating wire mounting, surface mounting and other 10 parts.

In the IPC-A-610C document, electronic products are divided into level 1, 2, 3, the higher the level, the more stringent the quality control conditions. The three levels are:

Level 1 products, known as general-purpose electronic products. Including consumer electronics, certain computers and their peripherals and products whose main purpose is to use the function.

Level 2 products, known as specialized service electronic products. Including communications equipment, complex industrial and commercial equipment and high-performance, long-life measuring instruments. In the usual use of the environment, this class of products should not occur in the failure.

Class 3 products, known as high-performance electronics. Including high-reliability, long-life military and civilian equipment that can operate continuously. These products in the use of the process is absolutely not allowed to interrupt the failure, at the same time in harsh environments, but also to ensure that the equipment is reliable startup and operation. For example, medical life-saving equipment and all military equipment systems.

For all levels of products, IPC-610C specifies "target conditions", "acceptable conditions", "process warning conditions" and "defect conditions". "Defect conditions" and other acceptance conditions. These acceptance conditions are the basis for product inspection, but also the work of the staff production site standards, but also become an important part of the training of employees of electronic production and assembly companies.
