I've noticed -- in my case with an automotive lighting junction box for the brake lights in a 1988 Toyota Camry -- that burned traces are not only from high current (although that's the usual cause), but can wear out over time. I'm not sure if that's from normal use or from slight periodic surges. Actually, in the case I'm talking about, it was more the connector pins which had problems, and they weren't corrosion based, but rather from current. YMMV.
Your wife has to give you big kudos for sleuthing out that fix. I have a pretty handy husband, but in my house, that would have been a $700 repair bill hit. It's nice to hear a fix-it story where engineering rigor and diligence not only took center stage, but paid off in spades.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
