This tungsten coil thermal filament is an electrically heated evaporation source component and requires fit and power-delivery verification before installation. Use only in a vacuum deposition source assembly configured for the F14 4-wire coil geometry.
- Geometry and holder compatibility: Confirm the F14 geometry reference and holder fit before installation.
- Electrical system matching: Match the filament voltage, current, and power requirements to the evaporation power supply and source assembly.
- Pre-energization verification: Do not energize the filament before mechanical fit and electrical compatibility are verified.
- Deposition system integration: Install the filament only in a vacuum deposition source assembly intended for thermal filament evaporation.
- Mechanical integrity: Maintain the 4-wire coil geometry during handling so the filament seats correctly in the source holder.
This procedure confirms source fit and power supply compatibility before the filament is energized. Complete all verification steps before installing the filament in the evaporation source.
Required Equipment: Evaporation source holder, Evaporation power supply
- Confirm geometry fit
Confirm the F14 geometry reference and holder fit for the target evaporation source assembly. - Verify package quantity
Verify the required package quantity before preparing the filament for installation. - Match electrical ratings
Match the filament voltage, current, and power requirements to the evaporation power supply. - Mount the filament
Mount the filament securely in the source holder without distorting the coil geometry. - Energize the source
Energize the evaporation source only after mechanical fit and electrical connections are confirmed.
What is the significance of the F14 geometry and 4-wire 0.030 in diameter construction for thermal evaporation uniformity?
The F14 geometry with 4 wires of 0.030 in diameter defines a specific coil configuration of 8 coils, 2 in L x 1 in H x 1/2 in ID, which ensures a consistent heating profile and evaporation rate. The electrical ratings of 8.8 V, 68 A, and 598 W are matched to this geometry to achieve a rated operating temperature of 1800 °C, critical for reproducible thin-film deposition in vacuum thermal evaporation systems.
Can this tungsten coil filament be used with any standard evaporation power supply?
The filament requires a power supply capable of delivering 8.8 V at 68 A (598 W). Users must also verify that their source holder accommodates the F14 geometry dimensions (2 in L x 1 in H x 1/2 in ID) and that the wire diameter of 0.030 in fits the contact clamps. Compatibility should be confirmed before purchase to avoid electrical mismatch or mechanical fit issues.
What handling precautions are required for tungsten coil filaments to prevent contamination or breakage?
Tungsten filaments are fragile; handle with clean gloves to avoid oil contamination, which can cause uneven heating or arcing during 1800 °C operation. Store in the original packaging to prevent deformation of the coil geometry. Ensure proper vacuum conditions and shielding to prevent oxidation at high temperature.
Tungsten coil thermal filament with F14 geometry, 4 wires x 0.030 in diameter, rated for 1800°C operation at 8.8V, 68A, 598W. Suitable for thermal evaporation vacuum deposition when geometry and electrical parameters are matched to the source holder and power supply.
Positive
- Defined electrical and thermal specifications: Rated at 8.8 V, 68 A, 598 W, and 1800°C, enabling precise integration with matched power supplies and deposition systems for repeatable thermal evaporation.
- Fixed wire geometry for source consistency: The 4-wire, 0.030 in diameter construction provides a reproducible source configuration for thermal filament evaporation workflows.
Trade-offs
- Geometry-specific holder compatibility: The F14 geometry must be verified against the evaporation source holder before purchase; not all vacuum deposition systems accept this form factor.
- Fixed electrical loading constraints: The fixed voltage, current, and power ratings require the evaporation power supply to deliver 68 A at 8.8 V, which may limit use with adjustable or lower-rated supplies.
