Hello,

Here is another question related to materials in the electronic industry...(I've got millions!)

On using conductive adhesives in micro electronics we have found that sometimes the resistivity in conductive adhesives, epoxi and silver flakes, increases upon repeated curing/heating.

A test was performed and a resistivity change was recorded upon repeated curing. Some time later the experiment was repeated, under exactly the same conditions as far as we know,  but no change in resistivity ocurred.

Has anyone experienced the same?
What can be done about it?
Can it be avoided or is it a "naturally occuring" phenomena?
