IPC-SM-782A
August 1993 A standard developed by IPC
Amendment 1
October 1996
Amendment 2
April 1999
The Principles of
Standardization
In May 1995 the IPC’s Technical Activities Executive Committee adopted Principles of
Standardization as a guiding principle of IPC’s standardization efforts.
Standards Should:
• Show relationship to Design for Manufacturability
(DFM) and Design for the Environment (DFE)
• Minimize time to market
• Contain simple (simplified) 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
Notice
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 sell-
ing 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.
IPC Position
Statement on
Specification
Revision Change
It is the position of IPC’s Technical Activities Executive Committee (TAEC) 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 standard/guideline is updated and a new revision is pub-
lished, 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 lastest revision. Adopted October 6. 1998
Why is there
a charge for
this standard?
Your purchase of this document contributes to the ongoing development of new and updated
industry standards. Standards allow manufacturers, customers, and suppliers to understand one
another better. Standards allow manufacturers greater efficiencies 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 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 in order to allow as many companies as possible
to participate. Therefore, the standards revenue is necessary to complement dues revenue. The
price schedule offers a 50% discount to IPC members. If your company buys IPC standards,
why not take advantage of this and the many other benefits of IPC membership as well? For
more information on membership in IPC, please visit www.ipc.org or call 847/790-5372.
Thank you for your continued support.
