RE: Any scope photos of different resistors...

Ah. Your wording helps clear up a lot for me. It makes sense that micro arcing would be more pronounced with technologies using a depositing or sputtering process to form the conductive paths. I suppose it's difficult to really characterize this problem generally since it must have much to do with specific manufacturing process and materials.

Very interesting. Thanks for the explanation. I'd previously come across a fellows webpage briefly mentioning "contact" noise within conductors/ resistors etc. caused from micro arcing from voids and impurities. One co-worker/mentor of mine has used the term "Excess noise" and didn't explain it to me. Good to finally sort of tie these loose ends into a slightly neater bundle.
