Anyone,

I have been told that a no clean paste post curing
will leave a white haze or residue around the well.
And, that this haze is a TIN OXIDE.  My question
is:  Is this ok?  Should we be concerned?  What 
chemistries could react with TnO2 causing corrosion?

My experience is oxide can be hazardous to the 
assembly, i.e. corrosion, tin wiskers etc.
