MATERIALS: Master Bond has introduced a thermal adhesive film called FL901AO. It is formulated to function as the preferential heat-transfer path between heat-generating components and heat sinks or other cooling devices. The 100 percent solid, B-stage adhesive-preform provides a high bond strength, no-mess solution to electronic assembly and other industrial bonding and sealing operations. The FL901AO epoxy preform cures quickly at quite moderate temperatures, e.g. one hour at 250F (125C) or 30-40 min at 300F (150C). Also, squeeze out during bonding is almost non-existent. While FL901AO exhibits a thermal conductivity on a level of 10 BTU•inch/ft²hrF, it is highly electrically insulating, with volume resistivity exceeding 10×1012 ohm-cm. The properties of FL901AO are substantially maintained over a wide temperature range from -100 to 400F and upon prolonged exposure to harsh environmental conditions such as moisture, heat and other chemicals. It also features outstanding resistance to thermal shock, vibration and impact.Master Bond’s FL901AO film preform is available in a range of film thicknesses and can be laser or die cut to the configuration of any part. Master Bond also offers the extra service of applying the preformed epoxy film directly onto parts and then returning them to the end user for assembly.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
