This directive specifies that each component within an assembly must meet the specified maximum concentration limit of 1000 ppm, by weight.</p> <p>The EMPF has the capability to quickly perform lead-free screening using a non-destructive test method called X-Ray Fluorescence (XRF). XRF is also advantageous in that it does not require sample preparation and only minimal operator training. Since a component part number or descriptor may not fully specify RoHS compliance, use of XRF can help alleviate uncertainty. Figure 2-1 shows the XRF spectrum of a sample component that contains an amount of lead which exceeds the RoHS maximum concentration limit.</p> <p align="center"><img src="images/fig2-1.gif"></p> <p>The customer's assembly contained many components mounted to a circuit board. Using XRF, the EMPF determined that one of the components mounted to the board did in fact contain a SnPb finish and was non-compliant with RoHS. A lead-free replacement for the specified component was recommended. </p> <p>The EMPF also offers a comprehensive lead-free training seminar. This training course provides an extensive overview of RoHS legislation and discusses materials, manufacturing processes, and reliability differences associated with lead-free soldering. Understanding the most recent RoHS legislation is essential in remaining competitive in the high-tech industry; likewise, misunderstanding or non-compliance of the RoHS directive can potentially result in penalties and potential legal consequences. Many considerations must be taken into account when choosing the materials and manufacturing processes in order for an assembly to be lead-free RoHS compliant. The EMPF training course offers the necessary training for the student to become fully capable of lead-free implementation in the design and manufacturing environments.</p> <p>For more information on lead-free manufacturing or other classes available at the EMPF, including IPC certifications, please contact the registrar at 610.362.1295, via email at registrar@empf.org, or on the web at http://www.aciusa.org/courses. For a demonstration of the XRF, please contact the EAB coordinator, Mike Prestoy at 610.362.1200, extension 241 or via email at mprestoy@aciusa.org.</p> <p class="body_text"><img src="../../archive/updated/nfardella.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>
