sales01@cxflowmeter.com

 Working condition:
1. Vacuum coating
2. Semiconductor CVD
3. Ion implantation
 
Pirani Vacuum Gauge PRN10, PRN11, PRN14 cold cathode is used for semiconductor more
 
Different products for different ranges
Generally, a semiconductor factory uses hundreds of watches a year, and thousands of watches are used for popular national materials.

 
In the coating industry, there is a thin film on mobile phone casings, panels, etc. One of our products is mainly used for powder feeding and air blowing.
 
For example, there is a layer of gold powder and protective gas on the mobile phone shell. When coating, it is necessary to use gas to send the gold powder to the surface of the metal. come to have a color reaction with the powder, etc.), and the working environment when it is attached is a high temperature state. At this time, it is also necessary to blow nitrogen or argon at the same time to prevent oxidation. At this time, a gas flow controller is also required to control the amount of argon.

 
The coating must be evacuated. Only in the case of vacuum, the coating will not react with other gases in the air. The pressure is basically negative pressure. Need to use a vacuum gauge to measure the vacuum
