Background Theory > PCB Design > The Institute for Printed Circuits

The IPC (Institute for Printed Circuits) is a global trade association that develops standards, training programs, and certification programs for the electronics industry.

IPC is the global association that helps OEMs, EMS, PCB manufacturers, cable and wire harness manufacturers and electronics industry suppliers build electronics better. IPC members strengthen their bottom line and build more reliable, high-quality products through proven standards, certification, education and training, thought leadership, advocacy, innovative solutions and industry intelligence.

IPC standards are widely used in the design, manufacturing, and assembly of printed circuit boards (PCBs). IPC standards are updated regularly to reflect changes in technology and industry best practices. They are used by PCB designers, manufacturers, assemblers, and test engineers to ensure that PCBs are designed and manufactured to the highest standards of quality and reliability.

Here are some examples of IPC standards related to PCB design:

IPC-2221: Generic Standard on Printed Board Design

This standard provides guidelines and design rules for the design of printed circuit boards. It covers topics such as board size, layer stackup, trace width, spacing, and other factors that affect the electrical performance and manufacturability of the board.

IPC-7351: Generic Requirements for Surface Mount Design and Land Pattern Standard

This standard provides guidelines for the design of surface mount land patterns for components. It covers topics such as pad size, shape, and placement, and it provides guidance on how to ensure proper solder joint formation.

IPC-6012: Qualification and Performance Specification for Rigid Printed Boards

This standard defines the requirements for the manufacture of rigid printed circuit boards. It covers topics such as material specifications, electrical performance, and testing requirements.

IPC-2223: Sectional Design Standard for Flexible Printed Boards

This standard provides guidelines for the design of flexible printed circuit boards. It covers topics such as materials, layer stackup, trace routing, and termination.

IPC-4101: Specification for Base Materials for Rigid and Multilayer Printed Boards

This standard defines the requirements for the materials used in the manufacture of printed circuit boards. It covers topics such as material properties, testing methods, and performance requirements.
