Evaluation of circuit board quality and process improvement requires slicing as a basis for objective inspection and judgment. Slice analysis using metallographic equipment is an important means to check the thickness of PCB/PCBA internal circuits, number of layers, through hole aperture size, through hole quality observation, PCB/PCBA solder joint cavity, interface bonding status, and wetting quality evaluation.
Moresuperhard offers resin diamond cutting discs and metal diamond cutting discs specifically for cutting in the glass industry. It can be used to cut glass optical devices such as quartz glass, K9 glass, coated glass, etc. It can also be used to cut various glass tubes, glass spouts, high borosilicate glass tubes, capillary glass tubes, quartz glass, and crystallized glass.
