Line Width Tester XK25 PCB Maufacturing Machines Usage These instruments are suitable for measuring the widths of inner and outer range of semi PCB after etching(before solder masking).the distance between two lines, distance between holes and edge, diameters of round holes, blind holes and arcs can also be measured. In addition, measuring widths of IC wafer, thickness of films and LCD boards are available. Features (1)Precise Adopting high-precision focus distance adjustable device, image processing, automatic boundary and sub- pixel algorithms technologies. (2)Efficient (a)Red LED positioning. (b)Automatic boundary technology. (c)Perfect function of SPC statistics.
