IPC-T-50 M Released

IPC-T-50, “Terms and Definitions for Interconnecting and Packaging Electronic Circuits,” has just been updated.  The new Revision M is available from Document Center in paper format, for pdf download, in CD Rom format, and as a kit with both the paper and CD Rom copies included.  As IPC says, the IPC-T-50 defines the “language of an industry.”  It allows users to understand terms both by written definitions and the use of illustrations for better clarity.

What’s new in the IPC-T-50 M?  There are over 220 new or revised terms.  The new definitions include including terminology for conformal coatings, potting and encapsulation processes, stencil design, statistical process control, and flexible printed board technology.  And some out-of-date terminology has been removed from the 123-page publication as well.  This new edition replaces the now-obsolete Revision K from 2013, so it’s been about 2 years since the last revision.

Who should be using the IPC-T-50 M?  OEM, EMS or ODM Companies will all find the document can facilitate communications between staff and customers as well as ensuring a common understanding within the organization itself.

What about acronyms?  Acronyms used in the electronics industry are addressed in the publication’s Annex.  This is an invaluable aid in an industry beset by the use of acronyms!

What format of the IPC-T-50 is right for me?  Your document comes in single-user editions by default.  So while the CD Rom and the paper copy have a certain amount of portability, the pdf copy is definitely for the use of 1 person only.  And you’ll need to remember that electronic copies of the IPC standards do have the print function disabled.  So when using either the CD Rom or the pdf formats, your electronic copy will be your only copy, no printing allowed.  So make your choice based on these limitations.

Where can I get my copy of the IPC-T-50?  This is a copyright publication and must be purchased from an authorized distributor like Document Center Inc.  Order online at our webstore, www.document-center.com.  Or use this link to the order page for IPC-T-50 now.  Have questions and want to work with a real person?  Contact our staff by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  Our staff is well known for being responsive — Your call or email will be answered by someone with the expertise to answer any questions you might have.  Make Document Center your Standards Experts!

New IPC T 50 Revision K released on Electronic Circuit Terms and Definitions

There’s a new IPC T 50 Revision K, “Terms and Definitions for Interconnecting and Packaging Electronic Circuits,” and it’s available now.  The standard contains 120 pages of definitions, listed alphabetically, with a classification code that allows for review of terms by topic.  Additionally, Appendix A is an Acronym Listing, which can be handy when working with standards!

Changes in the IPC T 50 Revision K include more than 220 new or revised terms.  These include new terminology for thermal properties, etchback, assembly processing, hole drilling, and microvia technology.

Another nice thing about this standard is the liberal use of figures and tables to illustrate exactly what is meant by various terms.  These examples can be in the form of flow charts (circuit design), drawings (printed board viewing orientations), graphs (typical characteristic curve) or formulas (feature location).

Document Center Inc. is an authorized reseller of the IPC standards.  Most are available in both paper and CD Rom format, although the CD Rom’s have the print functionality suppressed.

New IPC-T-50 Revision J on Terms and Definitions for Interconnecting and Packaging Electronic Circuits

IPC-T-50 Revision J, titled “Terms and Definitions for Interconnecting and Packaging Electronic Circuits,” has just been released.   This essential industry standard provides descriptions and illustrations of electronics interconnect industry terminology to help users and their customers break down language barriers.

The new 121-page Revision J contains nearly 400 new or revised terms, including new terminology for chip scale and area array packaging, cable and wire harness technology, assembly processing, moisture sensitive components, and microvia technology.  IPC-T-50 also includes commonly used industry acronyms.

The standard was developed by the Terms and Definitions Committee of IPC.  It replaces all previous editions of the standard through Revision H dated 2008.

This standard and all  IPC documents are available from Document Center Inc. at our website, www.document-center.com.  Or you can contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We’ve been an authorized distributor of the IPC standards since the 1980’s.


MIL-STD-883 H – The DoD’s top standard for Microcircuits — Plus a list of other relevant standards

MIL-STD-883 Revision H, entitled “Test Method Standard – Microcircuits,” is Document Center’s all-time best selling military standard.  It provides approximately 700 pages of tests for microelectronic devices suitable for use within Military and Aerospace electronic systems.  It includes basic environmental tests to determine resistance to deleterious effects of natural elements and conditions surrounding military and space operations; mechanical and electrical tests; and workmanship and training procedures.

Revision H was released on 2/26/2010 and compliance with the standard was required by 9/30/2010.  Usage of the standard is mandated as part of a contract with the U.S. government.

The document is intended to be used in conjunction with several other major military documents:
MIL-PRF-19500 – Semiconductor Devices, General Specification For.
