Have you been watching the Olympics? I knew I had been watching maybe TOO much of the Olympics when I heard that the medals were made from recycled, melted down circuit boards.
No concerns here about head-in-pillow, solder joint reliability, halogens and all the other topics that make up the work lives of PCB assemblers.
More trivia: each medal is laser etched for that personal touch. Not quite the same as the goal of making the original circuit boards which is to make thousands, if not millions, each one exactly the same as the one before. However, it is a great reward for the world class athletes' years and years of training and for surviving the Olympic experience.
