I. function check:

check whether the appearance of the mobile phone is damaged? Start up and check whether the operation function is normal

for example, dial the phone, adjust the volume button, take photos, play music and movies, and check whether the speaker plays normally

II. Cleaning the mobile phone:

1. Turn off the power of the mobile phone

2. Clean the surface of the mobile phone with a small cloth stained with an appropriate amount of alcohol, and remove the removable back cover for cleaning

3. Start the dust suction switch of the machine and use the dust suction pipe to suck the places with gaps /holes in the mobile phone

4. Turn off the dust suction switch

3. Select the appropriate fixture for the mobile phone:

1. Select an appropriate fixture according to the size of the mobile phone. Note that the fixture cannot be too tight to avoid crushing the mobile phone screen. If the fixture is too large, put a small gasket next to the fixture

2. Insert the mobile phone into the space in the fixture, and pay attention to avoid keys or holes, so as not to affect the coating effect. The coating can be carried out only after the inspection is completed

IV. operation process of vacuum coating:

1. Drop an appropriate amount of nano liquid

into the two atomization cups. 2. Put the clamped mobile phone into the vacuum atomization chamber

3. Cover the vacuum chamber

4. Press the start button (pay attention to the air pressure of the barometer during vacuum atomization, the normal is 0.04-0.06, and pay attention to whether the nano liquid atomization is normal)

v Drying mobile phone:

1. After vacuum coating, take out the mobile phone

2. Put the mobile phone into the oven for baking for 5 minutes

I. operation of electric control cabinet
1 Boiling water pump and air source
2 Turn on the main power supply
3 Turn on the power supply of the maintenance pump and vacuum gauge, and the vacuum gauge position v1. Wait until its value is less than 10, and then enter the next step of operation. It takes about 5 minutes
4. Turn on the mechanical pump and pre pumping, turn on the power supply of the turbomolecular pump and start it. Change the vacuum gauge switch to V2 position and pump it until it is less than 2. It takes about 20 minutes
5. Observe that after the reading of turbomolecular pump reaches 250, turn off the pre pumping, turn on the front machine and high valve to continue vacuumizing, and turn on the high vacuum meter on the right to observe the vacuum degree after the vacuumizing reaches a certain degree. Vacuum reaches 2 × The power supply of the electron gun can only be turned on after 10-3
II. Operation of def-6b electron gun power cabinet
1 Total power
2 Turn on the power supply of electron gun control I and electron gun control II at the same time: press the electron gun control I power supply and delay switch, the delay, power supply and protection light will be on, and the delay and protection light will be off after three minutes. If the rear door is not closed or the water flow relay is faulty, the protection light will be on constantly
3. Turn on the high voltage, the high voltage will reach more than 10kV, adjust the beam current to about 200mA, the curtain grid is 20V /100mA, the filament current is 1.2A, and the deflection current swings between 1 ~ 1.7
III. shutdown sequence
1 Turn off the high vacuum meter and molecular pump
2. When the molecular pump displays 50, turn off the high valve, front stage and mechanical pump in turn, which takes about 40 minutes
3. When it is below 50, turn off the maintenance pump
