LASER DRILLING PROCESSES FOR MAKING FABRIC AND FILM FORMING DEVICES

摘要

A method of forming an apertured support member is accomplished by directing a laser beam at a workpiece, focusing the laser beam at the top surface of the workpiece, moving the laser beam in a series of raster scans over the surface of the workpiece. During each scan, the laser is turned on at predetermined intervals to drill one or more discrete portions of each of the apertures to form apertures surrounded by a plateau on the resulting support member.
