RCA engineers and scientists in Moorestown, New Jersey – where they now work for GE – claim to have developed an insulating material that maintains its stability during the processes used in making thick-film hybrid circuits, and say it is a truly a revolutionary development, not just for RCA but for the whole electronics industry: the material is said to solve two major problems faced by industry – it remains stable no matter how many times it is reheated, and it is a true hermetic dielectric, making it easier for industry to use copper rather than the gold, platinum and other precious metals that are used extensively in microcircuits.
