I'm hoping some tech-net metallurgist/alchemist or
other wizardly type can help me with this.
I had a stray thought this weekend and can't seem
to find the flaw in my logic.
Here is how the thought process went;
-Copper oxidizes and must be coated to maintain
solderability.
-Certain copper alloy's remain solderable even
after long term storage and exposure to hand oils etc. (i.e.;alloy
752)
-Why isn't a corrosion
resistant alloy used in the manufacture of PCB's?
I know the electrical resistance is higher for
alloy's but it seems this could be compensated for the same as trace resistance
is now, just get a new set of numbers.
What am I missing, this is really driving me nuts.
