Alumina Ceramic Substrate Laser Cutting Processing Our company has been equipped with high precision laser cutting processing installations. The lasers are used for scribing,cutting and drilling substrates ( Minimum hole diameter:0.1mm ;Minimum hole spacing betwwen holes:0.2mm; circular accuracy:0.05mm;width of cutting seam:0.1~0.15mm; Depth of cutting seam:30% ~ 50% of thickness of ceramic substrates;thermal trsnsmissiong region:0.025mm).It has high cutting accuracy,very small tolerance,eliminating the time -consuming and costly tool fabrication stage,as well as increasing the goods supply efficiency by s big margin and shortening the processing circle. Laser cutting method allows to produce substrates with various outside contour geometries, hole patterns,cut-outs and snap-lines. Laser-scribed multiple substrates can be supplied in all common machine formats from 2 inch x 2 inch to 5.4inch x 7.4 inch ,the thicknesses of processing usbstrates are 0.25,0.38,0.5,0.63,0.76,1.0mm.
