Interesting question....

on my motherboard the ram pin where highly corroded...

that's one of the reason why I removed them and installed socket of good 
quality...

I guess that for some time I stopped the corrosion...


strangely the 40 pin chips have their pin in a relatively good quality

when I see the strange color of the board I guess that some part were 
expose to light  (the varnish turned almost brownish)
and some other part it kept the same color as the original...

there were a lot of rust on the shield around  the clock...
