Nov. 11, 1968 - Although these harmless-looking particles of solder and other bits of manufacturing debris are dwarfed by an Ordinary thumbtack, they are large enough to Sabotage the electronic systems o spacecraft, computers, or even some home appliances. By combining an ultra sensitive listening system with sophisticated electronic and mechanical understanding engineers at the General Electric Research and Development Denture have developed a highly sensitive technique to detect and many cases, identify such foreign particles before they can damage expensive or critical equipment. The new quality control technique - sensitive enough to detect particles as small as a single grain of table salt - is expected to have numerous applications on the production on the lines of manufacturers of military and aircraft electronics, and various electronic and mechanical space components.
