<p>A heat-dissipating accessory plate for high speed drilling, prepared by adhering a composite material which is a solid state, abrasion-resistant, lubricating coating comprised of nano-structure powder and a high heat-conducting compound, over a supporting material, and then covering a lubricating layer over said composite material, can provide an action of grinding and lubricating a drill bit as well as dissipate heat generated during drilling processing on a printed circuit board.</p> |
