Method for using a blade assembly cover

摘要

A gang blade assembly which controls the trajectory of detritus from a ball grid array substrate dicing operation is described. The assembly includes a cover which partially encases a hub with a plurality of blades. A brush is mounted on the cover to disrupt an air flow created by rotation of the hub and blades. The brush extends beneath the cover and has bristles which contact the hub. The bristles also serve to clear the hub of any detritus produced during dicing. More than one brush may be mounted on the cover.
