    <![CDATA[<strong>Author:</strong> <a href="https://www.PCBLibraries.com/forum/member_profile.asp?PF=180">tboyer</a><br /><strong>Subject:</strong> 1418<br /><strong>Posted:</strong> 09 Sep 2014 at 11:28am<br /><br />Maybe not what allot of companies are dealing with<br>but to design a pattern for the Flex of a Flex board or Rigid-Flex<br>board requires modifying the solder mask in such a way that<br>your software currently cannot build to. See figure 9 of IPC-2223.<br>I think this would save me valuable time because I currently<br>have to use the software to create the pattern then go <br>into Layout pattern tool and modify the pad and solder mask.<br>Then leave a note in the library that this pattern was modified<br>for Flex. how it was modified and what it looks like is only<br>visible through the Layout tool.<br>]]>
