In the interest of improving the ease and repeatability of the processes involved in manufacturing, as well as maintaining the quality of the end product, industry standards have been developed for use by the electronics manufacturing community. As new technologies are developed and implemented, the need to keep in step with these changes demands ongoing revisions to the standards utilized in production and quality control. Historically, electronic assembly standards contained more comprehensive and tutorial information relating to principles and techniques; however, the standardization of methods has resulted in conflicts because process methods have changed faster than the standards.</p> <p>The EMPF now offers training in the IPC J-STD-001E (Requirements for Soldering Electrical and Electronic Assemblies), which is the latest version of this industry standard. Although there is not sufficient space here to address all the changes and additions to the newest revision, it is the purpose of this article to give an overview of what has changed between this and the previous revision. </p> <p>The most noticeable change to this document is the general layout of the text. The former two column format has been replaced by a simple page format to improve clarity and make the document easier to navigate. Additionally, the previous revision utilized text boxes to specify the condition of materials or processes that did not conform to the standards requirements. Within the latest revision these conditions are stated in brackets directly adjacent to the referenced text to avoid referencing the wrong clause within the text (which sometimes occurred with use of the old text boxes). </p> <p>In an effort to aid in connecting the J-STD-001 to the associated Space Addendum document, the new revision contains space shuttle shaped icons located adjacent to the clauses that are altered within the "E" revision of the Space Addendum.</p> <p>The following are significant technical revisions and additions to the J-STD-001.</p> <ul style="list-style-image: url('images/bullet.gif')" > <li>The addition of easy to read tables regarding the mechanical attachment of a wire/lead to a terminal post for the purpose of clarifying the difference between acceptable conditions, process indicators, and defects. Also, new terms have been added to delineate between mechanical attachment variances (e.g., overlap vs. overwrap).</li> <li>Expanded criteria for the use of heat shrinkable soldering devices. Expanded criteria for identifying insulation damage of wires attached to terminals (Figure 6-1). These additions bring the J-STD-001 into line with the criteria stated in the IPC/WHMA-A-620 document (Requirements and Acceptance for Cable and Wire Harness Assemblies). </li> <li>The addition of criteria for flattened post/nail-head surface mount technology (SMT) terminations (except for Class 3 products) and the expansion of surface mount area arrays into three categories (e.g., collapsible ball, non-collapsible ball, and column arrays).</li> <li>The addition of staking criteria specifying coverage limits on a variety of component types and stating magnification limits for visual assessment of adhesive application (Figure 6-2).</li> </ul> <p align="center"><img src="images/fig6-1.gif"></p> <p align="center"><img src="images/fig6-2.gif"></p> <p>The J-STD-001E Applications Specialist (CIS) training provides a modular approach to certification training. The program is a combination of lecture and hands-on soldering skills training. There are five modules, with each module requiring about eight hours to complete. Module One is required, a prerequisite to the other four optional modules of the course. There is no hands-on component to Module One; however, successful completion is dependent upon passing an open and closed book written exam with a minimum score of 70% in each test. This is a change in that the successful completion under the previous revision required only an average of 70% between the two exams.</p> <p>Instructor Certification (CIT) in the J-STD-001E is not modular. Instructors must demonstrate soldering skills, defect recognition and pass a comprehensive test covering the requirements of all five modules.</p> <p>If you would like to attend a training session and become certified in the most up to date version of the IPC J-STD-001, call the Registrar at 610.362.1295 or send an email to registrar@empf.org.</p> <p class="body_text"><img src="../../archive/updated/rdillman.gif"></p> </div> </td> <!-- InstanceEndEditable --> </tr> <tr> </tr> </table> <br> <table width="100%" border="0"> <tr> <td colspan="2"><div align="center"> <p><em>The EMPF is a U.S. Navy-sponsored National Electronics Manufacturing Center of Excellence focused on the development,<br> application, and transfer of new electronics manufacturing technology by partnering with industry,<br> academia, and government centers and laboratories in the U.S</em></p> </div></td> </tr> <tr> <td class="footer">ACI Technologies, Inc - - <a href="http://www.aciusa.org">www.aciusa.org</a> - - (610)362-1200</td> <td><div align="right"><a href="http://www.navymantech.com"><img src="http://www.empf.org/empfasis/archive/images/mantech.gif" width="144" height="42" border="0"></a></div></td> </tr> </table> <div align="right"> <!-- Start of StatCounter Code --> <script type="text/javascript" language="javascript"> var sc_project=350643; var sc_partition=1; </script> <script type="text/javascript" language="javascript" src="http://www.statcounter.com/counter/counter.js"></script> <noscript> <a href="http://www.statcounter.com/free_hit_counter.html" target="_blank"><img src="http://c2.statcounter.com/counter.php?sc_project=350643&amp;amp;java=0" alt="hit counter" border="0"></a> </noscript> <a href="http://www.empf.org/sitemap.htm"><em>[site map] </em></a> <!-- End of StatCounter Code --> <!-- Start of StatCounter Code --> <script type="text/javascript" language="javascript"> var sc_project=1902214; var sc_invisible=1; var sc_partition=17; var sc_security="759b802c"; </script> <script type="text/javascript" language="javascript" src="http://www.statcounter.com/counter/counter.js"></script><noscript><a href="http://www.statcounter.com/" target="_blank"><img src="http://c18.statcounter.com/counter.php?sc_project=1902214&java=0&security=759b802c&invisible=1" alt="website statistics" border="0"></a> </noscript> <!-- End of StatCounter Code --> </div> </body> <!-- InstanceEnd --></html>
