Has anybody in the industry heard about RMA flux being corrosive to plastic
parts?  One of our component suppliers claims that plastic parts do not
seal around the lead frame adequately during periods of high temperature
exposure and that flux can easily entrap inside and cause corrosion.
However, our supplier seems to be particularly concerned with RMA flux and
recommends a low residue flux instead?  My question is, if flux can get in
there so can anything else such as cleaning solvents.  Please let me know
if anybody has been exposed to or heard of this problem.

     If anyone can respond to her question, your help would be greatly
     appreciated.
