TECHNICAL PARAMETER

NST Four sources thermal evaporating system is suitable for coating most of metallic and organic materials film up to 2″ size from 200 ºC to 1500 ºC (or 200 ºC – 1700 ºC with an optional B-type thermocouple).The sample stage can be rotated to obtain a more uniform film.The evaporating system is small in size, which can effectively save laboratory space; it is easy to operate and has strong adaptability to different materials, so it is widely used in the laboratories of universities and research institutes.

NST Four sources thermal evaporating system main features:

1. 280 mm O.D.×260 mm I.D.×310 mm Height quartz chamber for easy cleaning and sample loading

2. 2″ Dia rotatable evaporating sources for the uniform film coating

3. Tungsten coil heater and alumina crucible for high-temperature coating up to 1700 ºC

4. Precision temperature control with 30 programmable segments and +/- 1 ºC accuracy

5. High vacuum can be achieved up to 1.0E-5 Torr via optional turbopump

6. Gas flow port and valve are built in for chamber purge and CVD possibility

NST Four sources thermal evaporating system specifications:

Input Power
  • Input voltage:  AC 208 – 240 V 50/60 Hz, single phase  ( 110V AC is available via 1500W transformer )
  • Input Power: 1200 W
  • output power:12 V, and 30 A max current. Recommended working current <30 A
  • Power cable included without plug
Temperature Control & Heaters
  • Four Alumina Evaporating Crucibles with 3 mL each capacity. Four sources cannot be used at the same time. The multilayers deposit would be done one by one.
  • Tungsten coil heater with a thermocouple is built in at the        bottom of alumina crucible (for temperature control).
    • Standard S type thermocouple (included and installed) – heating from 200℃-1500℃
    • Optional B-type thermocouple (at extra cost) – heating from 1200℃-1700℃
  • One digital temperature controller with 30 programmable        segments and +/- 1℃ accuracy.
  • The time settings of temperature controller are in seconds.  Recommend to limit the temperature heating / cooling rate to 0.3℃/s (or 20℃/min) below 1200℃, and limit to 0.15℃/s (or 10℃/min) from 1200℃-1700℃
  • For continuous heating above 1300℃, please limit the operation time to less than 1 hour to preserve the service life of bottom flange O-ring
  • For fast coating up to 2000℃, such as needed in Carbon coating, the user can remove thermocouple, alumina thermal block, and alumina crucible, load evaporation material directly into the tungsten coil heater, and use current manual control mode.
  • Four alumina crucibles (up to 1700℃) and two tungsten coil heaters are included.
Rotatable Sample Holder
  • One 50 mm Dia. rotatable sample stage and its shutter are installed on top flange.
  • Rotating speed: 5 rpm
  • The distance from sample holder to evaporation source is adjustable from 40 mm to 85 mm
Vacuum
  • KF25 vacuum port is installed to connect to a vacuum pump
  • The highest vacuum may reach <1E-5 Torr by pumping overnight with optional Turbomolecular pump
  • A vacuum pump is required for coating. Please choose from the following Product Options
    • Double Stage Rotary Vane Vacuum Pump with vapor trap to eliminate the oil mist, which can reach vacuum up to 1.0E-2 Torr for evaporating noble metallic materials, such as gold, silver, and organic materials. Anti-Corrosive Capacitance Diaphragm Gauge is included
    • Compact Turbomolecular Vacuum Pump System is able to provide vacuum level up to 1.0E-5 Torr for evaporating oxygen sensitive materials, such as Al. Mg, Li, etc. A combined Pirani and cold cathode gauge are included with pump to measure vacuum up to 1.0E-8 Torr
Gas Inlet
  • 1/4 tube fitting is built in for chamber purge or forming gas processing
  • One needle valve is built-in to control gas flowing rate
Quartz Chamber Dimension O.D.:280mm  (11″),  I.D.: 260mm  (10.2″), Length: 310mm  (12.2″)
Warranty One year limited warranty with lifetime support
Net Weight 80 kg
