Abstract
A composite resinoid/diamond dicing blade includes diamond particles and a dry lubricant dispersed in a resin binder. The dry lubricant can be in powdered form, and is preferably selected from graphite, talc, molybdenum disulfide, tungsten disulfide, niobium disulfide, boron nitride, and ditellurides and diselenides of group V and VI metals, with molybdenum disulfide being particularly preferred. The dicing blade can be used in cutting a variety of substrates, such as in the production of ink jet printheads, electrical semiconductor chips, raster input scan (RIS) sensor bars, and magnetic heads.
