The filament must be operated within the specified voltage, current, and power limits to prevent electrical failure and thermal runaway. Use only in a vacuum environment to avoid rapid oxidation and contamination of the deposition source.

  • Electrical Matching: Confirm that the power supply can deliver 3.56 V, 78 A, and 278 W continuously without exceeding the filament's rated limits.
  • Vacuum Environment: Operate the filament only under vacuum conditions to prevent oxidation at the 1800 °C operating temperature.
  • Handling and Cleanliness: Handle the filament with clean gloves to avoid transferring oils or contaminants that can cause hot spots or premature failure.
  • Mechanical Fit: Verify that the P2 geometry fits the evaporation source holder without mechanical stress or distortion.

These steps cover the installation and initial operation of the P2 geometry tungsten filament in a thermal evaporation system. Follow all safety precautions for high-current and high-temperature equipment.

Required Equipment: Evaporation source holder, Power supply capable of 3.56 V, 78 A, 278 W, Vacuum deposition chamber

  1. Inspect the filament
    Inspect the tungsten filament for any signs of damage, deformation, or contamination before installation.
  2. Mount the filament
    Mount the filament securely into the evaporation source holder, ensuring the P2 geometry aligns correctly with the contact points.
  3. Connect electrical leads
    Connect the electrical leads to the filament terminals and verify that the power supply settings match the 3.56 V, 78 A, and 278 W specifications.
  4. Evacuate the chamber
    Evacuate the deposition chamber to the required vacuum level before applying any power to the filament.
  5. Apply power gradually
    Apply power gradually to the filament, monitoring the voltage and current to ensure they remain within the rated limits until the operating temperature of 1800 °C is reached.

What electrical specifications must be matched when integrating the P2 tungsten point source filament into an existing deposition system?

The filament requires a power supply capable of delivering 3.56 V, 78 A, and 278 W at an operating temperature of 1800 °C. These values are specified to ensure proper thermal evaporation performance and must be confirmed against the evaporation power supply and source assembly used in the deposition system.

Which geometry and holder parameters should be verified before purchasing the P2 tungsten point source filament?

Verify that the filament geometry reference P2, with 3 wires x 0.030 in diameter and overall dimensions of 4 ½ in L x 2 in x ½ in, fits the evaporation source holder. The wire count, diameter, and geometry are critical for proper seating and electrical contact in the vacuum deposition source assembly.

How do the available package quantities affect procurement for this tungsten filament?

The filament is offered in 5 pcs/package and 10 pcs/package options. Choose the package size based on expected consumption rate; the 10 pcs pack may reduce reorder frequency for high-throughput applications. Technical specifications are identical across both package sizes.

The Tungsten Point Source Filament (AF-PSP2-3W030) with P2 geometry and 3 wires of 0.030 in diameter is specified for 1800 °C thermal evaporation, drawing 3.56 V, 78 A, and 278 W. Its defined electrical and dimensional parameters allow precise matching to compatible source holders and power supplies, but the fixed geometry and wire count require verification of mechanical fit and electrical loading before integration into a deposition system.

Positive

  • High operating temperature: Rated for 1800 °C operation, enabling thermal evaporation of high-melting-point materials such as metals and dielectrics in vacuum deposition workflows.
  • Defined electrical parameters: Voltage (3.56 V), current (78 A), and power (278 W) are explicitly stated, facilitating direct comparison with power supply capabilities and reducing integration risk.

Trade-offs

  • Geometry-specific holder fit: The P2 geometry and 3-wire × 0.030 in diameter construction require mechanical verification with the intended evaporation source holder; incompatible holders will not accept this filament.
  • Electrical matching required: The specified voltage, current, and power must be matched to the evaporation power supply; deviations may cause suboptimal performance or damage to the filament or source assembly.
