This thermal filament must be installed and operated within rated electrical limits to prevent damage or equipment failure. The filament wires are mechanically fragile and require careful handling to avoid deformation.

  • Electrical Matching Constraint: Confirm the power supply voltage, current, and power ratings match the filament specifications (2.94 V, 54 A, 159 W) before energizing.
  • Mechanical Handling Constraint: Handle the filament by the base only to avoid bending the wire coils.
  • Temperature Limit Constraint: Do not exceed the rated operating temperature of 1800 °C to prevent filament degradation.
  • Environment Constraint: Store filaments in a dry, contaminant-free environment to prevent oxidation.
  • Installation Fit Constraint: Verify the F1 geometry and holder compatibility before installation to ensure proper seating.

Proper installation and operation of this tungsten filament ensures safe and effective thermal evaporation. Follow these steps to mount the filament, connect power, and prepare for deposition.

Required Equipment: Evaporation power supply with adjustable voltage and current, Vacuum deposition system, Tweezers for handling

  1. Inspect filament
    Inspect the filament for any visible damage, loose wires, or contamination before installation.
  2. Mount filament in holder
    Mount the filament securely in the evaporation source holder, ensuring the F1 geometry aligns with the electrical contacts.
  3. Connect power supply
    Connect the power supply leads to the filament terminals, matching polarity if required by the system.
  4. Evacuate chamber
    Pump the vacuum chamber to the required base pressure for your deposition process before applying power.
  5. Ramp to operating conditions
    Gradually ramp the power supply voltage to the rated 2.94 V while monitoring current to avoid thermal shock.

What are the electrical and thermal specifications of the Atomfair F1 tungsten coil filament for thermal evaporation applications?

The F1 tungsten coil filament is rated for a maximum operating temperature of 1800 °C with electrical specifications of 2.94 V, 54 A, and 159 W. These values must be matched to the evaporation power supply and source assembly to ensure proper performance and avoid overloading.

What is the wire configuration and dimensional geometry of the F1 tungsten coil filament for fitting into vacuum deposition source holders?

The filament features 3 wires of 0.030 in diameter, formed into 10 coils with overall dimensions of 4 in length, 1 in zone, and 1/16 in format. The F1 geometry reference and these dimensions must be confirmed against the holder fit before purchase to ensure compatibility with the deposition system.

The Tungsten Coil Thermal Filament (F1 geometry, 3 wires x 0.030 in diameter) provides a precisely specified 1800°C thermal evaporation source with defined electrical loading of 2.94V, 54A, and 159W, suitable for vacuum deposition systems requiring repeatable filament performance.

Positive

  • High-temperature tungsten filament: Rated for 1800°C operation, the filament supports thermal evaporation of refractory materials without requiring a higher-temperature source.
  • Defined electrical parameters: Voltage (2.94V), current (54A), and power (159W) are explicitly stated, enabling direct match with the evaporation power supply and source holder during procurement.

Trade-offs

  • Geometry compatibility required: The F1 geometry and 3-wire × 0.030 in diameter must be verified against the source holder before purchase; a mismatch may require adapter components or replacement.
  • Temperature limit is 1800°C: The filament is rated for a maximum operating temperature of 1800°C; exceeding this limit risks rapid failure or contamination of the deposition chamber.
