Though it may be a late response, a number of electronic industry experts are questioning the scientific reasoning behind the European Union's (EU) Restriction of Hazardous Substances (RoHS). Those speaking out against the legislation claim the EU did not base the directive on robust science. They point to a recent study that shows the conversion to lead-free solder actually runs contrary to the best interests of the environment.
Sources agreed that RoHS will not be repealed, and they concede that China and the U.S. will go forward with their own legislation similar to RoHS. But they still raised the issue that RoHS is based on faulty assumptions about environmental damage. They note that RoHS was based on outdated concepts — such as lead leaching into the soil from discarded electronic products — that have since been proven scientifically wrong. RoHS dissenters have created a website called Pushback at www.Rohsusa.com to discuss their disputes with the science behind RoHS-style laws.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
