Why is there

a charge for

this document?

In May 1995 the IPC’s Technical Activities Executive Committee (TAEC) adopted Principles of

Standardization as a guiding principle of IPC’s standardization efforts.

IPC Standards and Publications are designed to serve the public interest through eliminating

misunderstandings between manufacturers and purchasers, facilitating interchangeability and

improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay

the proper product for his particular need. Existence of such Standards and Publications shall not

in any respect preclude any member or nonmember of IPC from manufacturing or selling products

not conforming to such Standards and Publication, nor shall the existence of such Standards and

Publications preclude their voluntary use by those other than IPC members, whether the standard is to

be used either domestically or internationally.

Recommended Standards and Publications are adopted by IPC without regard to whether their

adoption may involve patents on articles, materials, or processes. By such action, IPC does not

assume any liability to any patent owner, nor do they assume any obligation whatever to parties

adopting the Recommended Standard or Publication. Users are also wholly responsible for protecting

themselves against all claims of liabilities for patent infringement.

It is the position of IPC’s Technical Activities Executive Committee that the use and implementation

of IPC publications is voluntary and is part of a relationship entered into by customer and supplier.

When an IPC publication is updated and a new revision is published, it is the opinion of the TAEC

that the use of the new revision as part of an existing relationship is not automatic unless required by

the contract. The TAEC recommends the use of the latest revision. Adopted October 6, 1998

Your purchase of this document contributes to the ongoing development of new and updated industry

standards and publications. Standards allow manufacturers, customers, and suppliers to understand

one another better. Standards allow manufacturers greater efciencies when they can set

up their processes to meet industry standards, allowing them to offer their customers lower costs.

IPC spends hundreds of thousands of dollars annually to support IPC’s volunteers in the standards and

publications development process. There are many rounds of drafts sent out for review and

the committees spend hundreds of hours in review and development. IPC’s staff attends and

participates in committee activities, typesets and circulates document drafts, and follows all necessary

procedures to qualify for ANSI approval.

IPC’s membership dues have been kept low to allow as many companies as possible to participate.

Therefore, the standards and publications revenue is necessary to complement dues revenue. The

price schedule offers a 50% discount to IPC members. If your company buys IPC standards and

publications, why not take advantage of this and the many other benets of IPC membership as well?

Thank you for your continued support.

Standards Should:

• Show relationship to Design for Manufacturability

(DFM) and Design for the Environment (DFE)

• Minimize time to market

• Contain simple (simplied) language

• Just include spec information

• Focus on end product performance

• Include a feedback system on use and

problems for future improvement

Standards Should Not:

• Inhibit innovation

• Increase time-to-market

• Keep people out

• Increase cycle time

• Tell you how to make something

• Contain anything that cannot be

defended with data
