This filament requires a holder assembly that matches the P1 geometry and wire dimensions to ensure proper electrical contact. The power supply must be capable of delivering 2.76 V, 80 A, and 221 W without exceeding the rated operating temperature of 1800 °C.

  • Holder Compatibility: Confirm that the filament's P1 geometry and 4 wires x 0.030 in diameter fit the evaporation source holder without modification.
  • Electrical Matching: Verify that the power supply can continuously provide 2.76 V, 80 A, and 221 W to avoid electrical overload or filament damage.
  • Temperature Limit: Do not operate the filament above the rated temperature of 1800 °C to prevent deformation or failure.

Confirm the filament geometry and electrical specifications match the evaporation source assembly before installation. Proper alignment and secure electrical contact are essential for safe operation at high temperature and current.

Required Equipment: Evaporation source holder, Power supply capable of 2.76 V, 80 A, 221 W

  1. Verify holder fit
    Confirm that the P1 geometry and wire dimensions of the filament match the evaporation source holder assembly.
  2. Match electrical specs
    Verify that the power supply can deliver 2.76 V, 80 A, and 221 W continuously without exceeding the filament's rated limits.
  3. Select package quantity
    Select the required package quantity (5 or 10 pcs) based on the number of deposition runs needed.

What are the electrical specifications of the Tungsten Point Source Filament P1 geometry and why are they important?

The filament is specified for 2.76 V drive voltage, 80 A current, and 221 W power at its rated 1800 °C operating temperature. These values must be matched to the evaporation power supply and source assembly used in the deposition system to achieve correct resistive heating for thermal evaporation.

What physical dimensions and geometry must be verified for holder compatibility with this filament?

The filament has a P1 geometry with overall dimensions of 5 inches in length and 1/2 inch in height, using 4 wires each of 0.030 inch diameter. Users must confirm that their evaporation source holder accommodates this specific geometry and wire configuration before purchase.

This tungsten point source filament with P1 geometry and 4 wires x 0.030 in diameter is specified for 1800 °C, 2.76 V, 80 A, and 221 W, offering a defined thermal evaporation source configuration that requires careful matching to the deposition system's holder and power supply.

Positive

  • Predefined P1 geometry and wire specification: The 4 wires x 0.030 in diameter P1 geometry provides a reproducible filament configuration for consistent thermal evaporation source behavior.
  • Defined electrical and thermal ratings: Rated at 2.76 V, 80 A, 221 W, and 1800 °C, this filament enables precise matching to power supply and deposition process requirements.

Trade-offs

  • Requires exact holder and power supply matching: The P1 geometry and electrical ratings must be verified against the evaporation source holder and power supply before use; improper fit or mismatch can lead to poor performance or damage.
  • High-temperature operation necessitates careful handling: Operating at 1800 °C imposes thermal stress on the filament and requires appropriate safety protocols and compatible deposition chamber materials.
