Title (EN) MOSAIC POLISHING PADS AND METHODS RELATING THERETO
(FR) TAMPONS A POLIR MOSAIQUES ET PROCEDES AFFERENTS
Abstract:
(EN) This invention provides polishing pad tiles which, by virtue of their geometry and surface features, can be arranged to form mosaic pads having channels at the seams which facilitate the flow of polishing fluid during polishing of a workpiece.
(FR) Cette invention a trait à des carreaux de tampons à polir qui, du fait de leur géométrie et de leurs caractéristiques de surface, peuvent être disposés de manière à constituer des tampons mosaïques pourvus de canaux sur les lignes de jonction, ce qui facilite l'écoulement du liquide de polissage durant le polissage d'une pièce.
