Getting a multi-pin connector out of a multilayer PCB is difficult as it is easy to rip out the hole plating which can short the internal connections. Being very experienced at soldering and having the correct equipment helps a lot. After removing the connector I found that the PCB wasn't burned, only discolored. I bought a replacement connector, a Molex 44472-2050, from <a href="http://mouser.com" rel="nofollow">Mouser Electronics</a> (part #538-44472-2050). Soldering a new one in is always much easier than removal. After reinstalling the board and verifying it was functional again, I noticed that the connector area was rather hot - not from the connector but rather a pair of voltage regulators adjacent to it. The combined heat from them is adding to the problem so I installed a small fan to cool the area and prevent future meltdowns.jhansonxihttps://www.blogger.com/profile/02954133518928245196noreply@blogger.comtag:blogger.com,1999:blog-8230692678867105904.post-91423309814899544022009-03-27T06:59:00.000-04:002009-03-27T06:59:00.000-04:00This comment has been removed by a blog administrator.♥♥♥♥♥ Jennifer™® ♥♥♥♥♥https://www.blogger.com/profile/15369583052701337325noreply@blogger.com
