I have been burned a few times using downloaded library parts only
to find they are wrong. Found out by burning PCBs, which means lost
time and money.<br>
<br>
If you download libraries ALWAYS check them. IF you are lucky enough
to have a part that the manufacturer provides a .bxl file, you can
use a program like Ultra Librarian to create an Eagle symbol. It may
still need editing but the basics should be correct.<br>

<div>Hi Richie,<br>
<br>
</div>
This is one of the reasons why I never use the libraries
provided with CAD tools. The quality is just so varied,
rarely consistent, and full of unknown bugs. At least if I
fab a board with a mistake in a component I have created I
have only myself to blame! And quite honestly by the time
I've thoroughly checked a vendor library for correctness I
might as well have made it myself.<br>
<br>
</div>
<div>I separately maintain a catalogue of custom part numbers
in a spreadsheet (one sheet for each component type), and
when I have fabbed a board with a new footprint and tested
it I then mark that entry in bold so I know it works.<br>
</div>
<div><br>
</div>
Cheers,<br>
