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.
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.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
