Again, I have not used this chip.
The trace I mentioned before was the program trace. But I still think the MCLR part is different than the data sheet, data shows diode going VSS?

Other than that and a few sharp turns, I do not see a problem.

The sharp turn thing also give a real nice place for arcs to show up.
Whats the law? Things in motion want to keep going in the same direction? Even electrons.
