In the cutting process of precision dicing machine, there will always be various situations, and the most common problem should be the edge collapse of the workpiece, including: front collapse, back collapse, angle drop and cracks. There are many different factors that can lead to edge collapse, such as workpiece surface condition, mucous membrane condition, cooling water, blade and so on.
With the development of the semiconductor market, China has imported a large number of chips from the world, and the sales volume has set a historical record. Now, the global chip sales all depend on China's "face".
High hardness and wear resistance Hardness is the basic characteristic of mechanical blade material. In order to cut the chip from the workpiece, the hardness of the mechanical blade must be greater than that of the workpiece material.
