IPC-7351 Land Pattern Viewer and ToolsIPC-7351, Generic Requirements for Surface Mount Design and Land Pattern Standards, is supplemented by a suite of software tools composed of land pattern viewers, calculators and generators for the creation of new part libraries. The IPC-7351 Land Pattern Viewer is a shareware program that allows users to view component and land pattern dimensional data in tabular form as well as graphical images that illustrate how a component is attached to the land pattern on the board. Download the latest IPC-7351 Land Pattern Viewer here: IPC-7351 Land Pattern Viewer – Version V7.00 (.zip) IPC-7351 Land Pattern Viewer Usage Once installed, select the “Users Guide” tool bar button located on the main interface screen for the IPC-7351 LP Viewer. This .pdf document helps in familiarizing the user with the Viewer by providing detailed information on the following:
IPC-7351 Land Pattern Updates The IPC-7351 Land Pattern Viewer relies on library files for component and land pattern dimensional data. The extension for the library files is <.plb>. These .plb files provide the raw dimensional data necessary for the software to display components and land patterns in graphical forum. .plb files also contain parts attributes. Attributes hold vital statistical and descriptive data that every land pattern needs so other users can quickly identify the component characteristics. Attributes help organize data used to search for existing library parts. Detailed descriptions of how to utilize attributes can be found by selecting the “Users Guide” tool bar button located on the main interface screen for the IPC-7351 LP Viewer. As new component families are standardized by the industry, new .plb library files will be made available to users of the IPC-7351 Land Pattern Viewer. Download updated .plb files for any of the 3 IPC-7351 land pattern libraries (Least, Nominal, Most) here: www.pcblibraries.com/resources/LibDoc.asp (Note: You will no longer be on the IPC website) IPC-7351 Enhanced Software Programs The IPC-7351 Land Pattern Viewer is a shareware program that allows users to search and display existing land patterns for standardized component families. The Viewer is supported by additional, non-shareware software tools that allow for the calculation of new land patterns as well as the creation of new part libraries that store new component and land pattern data:

To obtain a copy of this successor to the IPC-SM-782, go to www.ipc.org/onlinestore and search on “7351” or contact IPC Order Entry at 1-847-597-2862. To learn more about the concepts provided in IPC-7351, contact John Perry at perrjo@ipc.org or download the January 2005 IPC Review Magazine cover article. Note on Manufacturer Part Number from original IPC-SM-782 Calculator:As IPC-SM-782 has been superseded by IPC-7351, IPC-SM-782 land patterns previously found under the "Manufacturer Part Number" database portion of SM-782 Land Pattern Calculator are no longer maintained by IPC. If you would like to obtain a copy of a previously submitted land pattern, please contact John Perry at perrjo@ipc.org and provide the component family name, company name and part number submitted. IPC-7351 Land Pattern Naming Convention The IPC-7351 standard provides an intelligent land pattern naming convention that aids in communication between engineering, design and manufacturing. Containing information on attributes such as component family, pin pitch, pin quantity and lead span, the convention also provides for enhanced search capabilities within the IPC-7351 Land Pattern Viewer.
