Vacuum coating equipment operation steps

Vacuum coating equipment operation steps

The operation of the vacuum coating equipment with reference to the equipment manual and vacuum coating machine each knob under the label instructions and dashboard pointer display. General situation is as follows:
1) check the vacuum coating equipment operation control switch in "off" position.
(2) open the total power switch, vacuum coating equipment power.
(3) low pressure valve. Open the charging valve, after hear air flow noise, start up bell valves, bell rises.
(4) fixed tungsten spiral heating installation. The PVDF film and aluminum plate fixed on the rotating disk. Put the aluminium wire wear in the spiral heater element. Clean up each position within the bell jar, ensure that no impurities dirt.
(5) fall in the bell jar.
6. Start the vacuum mechanical pump, vacuum coating equipment.
All landowners compound vacuum gauge power (compound vacuum gauge type: Fzh - 1 a).
A. "1" left knob clockwise rotation to point to the location 2 section of the heat.
B. low vacuum gauge pointer clockwise movement within "2", when the pointer to 110 ma, "1" rotate to the left knob to 2 section measuring position.
Today when the low vacuum gauge pointer within the "2" again moving clockwise to Pa 6.7, into the low pressure valve. "1" then left knob rotation to point 1 section measurement location.
Open cooling water pet-name ruby vacuum coating equipment, start the diffusion pump, heating 40 min.
Attending a low-pressure valve. Repeat all landowners action programs: "1" to point to the lower left knob 2 section measuring position. Low vacuum gauge pointer clockwise movement within "2", when the pointer to Pa 6.7, a high pressure valve (stem clockwise).
Such as low vacuum gauge pointer right within "2" to 0.1 Pa, gauge tube filament switch.
A. launch, zero measurement button "9" rotate to point to launch position.
B. lower left button "1" rotation to point 1 section measurement location.
