Role of Chip Grinding Disk

Chip grinding disk is one of the indispensable tools in semiconductor manufacturing, which is mainly used to cut and process materials such as silicon wafers. Chip grinding disk makes the surface of silicon wafers become flatter by grinding and lapping, which improves the quality and performance of the chip. At the same time, the chip grinding disk can also be used for the preparation of MEMS, LED, optoelectronic devices and microelectromechanical systems and other fields.

Second, the classification of chip grinding disk

According to the use of different purposes and processing materials, chip grinding discs can be divided into diamond grinding discs, aluminum oxide grinding discs, polyurethane grinding discs and other types. Among them, diamond grinding disc has high hardness, good thermal stability, strong corrosion resistance, etc.; alumina grinding disc has a good cutting effect, low loss, durability, etc.; polyurethane grinding disc has good elasticity, easy to repair, high finish characteristics.

Precautions for the use of chip grinding disk

1, before use, please check whether there is damage or deformation of the grinding disk, such as found problems should be replaced in a timely manner;

2, use should be based on the characteristics of the processed material to select the appropriate type of grinding disk and specifications;

3, when installing the chip grinding disk should be strictly in accordance with the requirements of the manual to avoid improper use leading to accidents;

4, the use of the period should be regularly check the wear of the grinding disk, timely replacement of the grinding disk to ensure the quality of processing;

5, in the use of chip grinding disk, should pay attention to safety, to avoid injury or cause accidents.
