Several reasons for the slow fine extraction of the vacuum coating machine
The vacuum coating machine's fine pumping is too slow, mainly from the following aspects:
1. The diffusion pump may not work well.
Solution: You can use an ionization gauge to connect to the pump port of the diffusion pump to see how much the diffusion pump can achieve with a single pumping. It depends on the pumping time and limit, and then compare.

2. There is a slight leak in the vacuum system.
Solution: It is necessary to slowly check for leaks and see if the vacuum retention time can reach the standard.
3. The cabinet is too dirty, and the air volume will be large if it is too dirty.

Solution: clean the cabinet
Fourth, the fore-stage vacuum is not good, and the ultimate vacuum of the mechanical pump or mechanical pump Garots pump is not good.
Solution: You can use a resistance gauge to detect the foreline pipeline separately.
