IPC has its headquarters in Bannockburn, Illinois, and has other offices around the United States and the world, including in India, China, Sweden and Russia. The American National Standards Institute (ANSI) has accredited IPC as a standard-developing organization. What are the IPC standards? They are the most widely recognized acceptability codes in the electronics industry.

What is the content of IPC standards?

Direct from IPC, the goals of adherence to their standards include:

·  To provide a standardized set of industry developed, recognized, approved and traceable training programs to enhance understanding and appropriate application of criteria in the standard.

·  To provide an understanding of accept/reject criteria to enhance an individual’s motivation and ability to consistently and correctly apply the technical discrimination criteria.

·  To teach methods and processes to improve an individual’s skills and ability to achieve acceptable workmanship.

·  To teach methods and techniques how to use, navigate, locate and to apply the criteria contained in a document to the appropriate class or classes of production.

To be accountable, reliable, and credible to our suppliers and also our customers, this is why ACDi values the adoption of IPC standards. Our customers can be assured we build only the highest quality products on their behalf, and that they can, in turn, reassure their own end users that products will perform.

What is the purpose of IPC component spacing?

The IPC component spacing guidelines are a third check on these potential physical problems. As long as designers follow the spacing guidelines, there should not be physical overlaps of components except in special circumstances that require additional engineering and development.

Component spacing guidelines also manage negative space—the places where components are not present. Negative space on a PCB can be just as important as the regions where components exist, and this space is particularly important when preventing electrical interference. If conductive traces or circuits are too close together, unintentional connections may form between them as electrons jump between circuits.

These unexpected connections reduce the strength of signals traveling through some regions of the PCB and can increase the amount of power flowing through other areas. Reductions in power can cause shorts or failures, while surges in power can cause physical damage or overloads.

Why IPC component spacing is important?

First, let’s review what some of the assembly problems are for PCB manufacturers when minimum spacing requirements aren’t met:

·  PCB layout constraints Component installation: Although automated placement equipment is extremely accurate, those systems still need enough room to operate in. Parts that aren’t candidates for machine placement, will need even more room for technicians to be able to work with them.

·  Soldering: For boards that are to be wave soldered, the spacing between parts is extremely important to prevent shadowing of smaller parts by larger. As with component installation, those that are to be manually soldered need enough room for the technician to be able to work with.

·  Test: There must be enough clearance between test points and components to allow access for the probes of the test fixture. There also needs to be proper clearance around the perimeter of the board for the test fixture outline.

·  Access: Printed circuit boards usually have connectors, switches, and other interfaces that require access for technicians. There needs to be enough clearance to fit fingers and tools in for a test, debug, rework, and normal operations.

What are the PCB IPC standards?

PC is the official name of the association which produces PCB-related standards. The association was formerly called the Institute for Printed Circuits (hence the acronym "IPC"), but is presently called the Association Connecting Electronics Industries—even though it retains the IPC moniker.

IPC, itself, is an international industry association consisting of more than 4,000 member companies that make, use, specify, and design PCBs and assemblies, including:

·  Advanced microelectronics

·  Aerospace and military

·  Automotive

·  Computer

·  Industrial equipment

·  Medical equipment and devices

·  Telecommunications industry
