The specific process of vacuum coating machine multi-arc ion coating machine

Start - check the instruments - preheat the diffusion pump - install parts, close the furnace door - evacuate to the set pressure P1 - fill the gas to the set pressure P2 - the workpiece rotates, complete the bombardment according to the set bombardment method and number of times - set Humidity, coating bias - coating pressure to the set value P3 - put in gas B according to the set flow - step-by-step bias coating for a certain time - out of the oven.

Vacuum Coating Machine Multi-arc Ion Coating Machine

The multi-arc ion coating machine mainly uses multiple metal evaporation sources as its cathode, and generates arc discharge between the anode and the anode. At this time, the evaporated particles of the target react with the gas entering the working chamber after ionization, thereby The produced compound is precipitated to form a film on the surface of the substrate to be coated. During the coating process, the vacuum pressure, arc source bias voltage and current, the flow of the gas introduced, and the vacuum temperature all require very precise setting and control.

Vacuum coating machine rotary vane vacuum pump

The rotary vane vacuum pump discharges a lot of black smoke or injects fuel during operation. If it is just turned on, it is still in the normal range, but it will not work. The solution to this situation is: the smoke indicates that the valve and the pipeline container outside the air inlet of the pump have been repaired. After the leak detection is processed, the black smoke will end.

Vacuum Coating Machine Electroplating Machine Nickel Plating

1. There are many burrs after the nickel plating process is completed, which means that the bph of the solution is too high to form hydroxides.

2. The bonding rate is low, and the adhesion between copper and nickel is very poor. If there is no activated deoxidation layer, peeling will occur. If the current is interrupted and the temperature is too low, the nickel plating will be peeled off.

3. Why are there small pits in the nickel plating of the vacuum electroplating machine? There is a reason for this. This is because the pits are the result of organic pollution. Larger pits indicate oil pollution, and poor mixing will have such consequences.

4. There are bubbles or peeling in the plating layer of the vacuum electroplating machine, which means that the pre-plating treatment is not good enough or the power-off time is too long, the current density is too large, the pH is too high or too low, and the temperature is too low, which will cause foaming or peeling. Phenomenon.
