Hard Lesson Leaarned

Looking back over archived stories, I had missed this one, now over a month old. I have several past product experiences using various conductive adhesives, and I had learned a very valuable lesson a few years ago. 

Without going into specifics, I can tell you I had designed myself into a corner, and needed to get an electrical component connected to the main circuit. Based on its unique mounting condition, a conductive adhesive was the obvious answer.  I simply plowed forward with the mounting method and the adhesive, and had first parts prototyped.

 When the component didn't function properly, I learned the current required for the component far exceeded the current capability of the conductive particles in the adhesive.  There was no way the adhesive as ever going to drive the component properly, and I was stuck.

This bad assumption kicked me back significantly, and I had to undergo a substantial redesign.  That's one lesson I'll never forget.

I do see a serious potential for use with surface mount components, particularly the very small ones with sizes under one mm. Those parts are a big challenge to work with by hand, which makes prototyping quite a challenge. A conductive adhesive could provide some help.

This should be quite handy in electrically connecting components in situations too tight for a wire or traditional connector.

Chemical Resistance

Well researched article. I am assuming that the silicone in the adhesive can also help increase inadvertent exposure to chemicals and possibly have good chemical resistance.

It is clear that stable electrically conductive adhesives can be of great value in quite a few applications. So the usefulness potential is quite high.

Mant years ago I had an experience with anelectrically conductive adhesive material that I used to assemble a switch. The problem was that I did not realize that the material was conductive at all. The result was that while the assembly was fine mechanically, the switch was always "on", which caused me quite a bit of puzzelment, since it was clear that the contacts were opening as desired. The end result was that I had to use a different switch and a mechanical means of attachment. But it was certainly an educational experience.
