Protecting Your Vacuum Pump During Vacuum Cutting

Vacuum cutting, a crucial process in the photovoltaic industry, especially in the fabrication of silicon wafers, relies heavily on vacuum pump technology. Due to the high hardness and brittleness of silicon wafers, traditional cutting methods often fail to meet the demands for efficient and high-quality processing. Vacuum cutting technology utilizes high-energy beams to melt, evaporate, or sublime materials in a vacuum environment, effectively removing residues under negative pressure to achieve precise cutting.

Advantages of Vacuum Cutting:

Fast cutting speed, narrow kerf width, minimal heat-affected zone, and low material loss contribute to increased processing efficiency and yield.

The Role of Vacuum Pump:

During vacuum cutting, maintaining a vacuum environment in the cutting chamber is essential. This helps reduce oxidation and nitridation of silicon wafers caused by oxygen and nitrogen. Vacuum pumps are employed for this purpose.

The Need for Intake Filters :

Installing intake filters on vacuum pumps is crucial. These filters prevent dust particles from entering the pump along with the intake air. Without proper filtration, dust particles can damage pump components, seals, and contaminate pump oil.
