Re: Potential heating problem with standard patch Cat5 panels

The maximum operating temperature for FR-4 is 130 degrees C (266 F). (may not be suitable for continuous operation). Boards routinely reach 200 C and above during the soldering operation.

Or the PC board material is faulty. I wonder if it is FR4.

If the patch panels are being damaged, there must be a whole lot more current involved than 350ma,
or the traces are very thin, or it has a different cause.
