The tungsten basket heater requires vacuum operation and precise electrical matching. Physical fit and power supply compatibility must be confirmed before use.
- Vacuum requirement: The heater is designed for vacuum evaporation and must be operated in an evacuated chamber.
- Electrical matching: The power supply must be able to deliver the specified voltage, current, and power without exceeding the heater's rating.
- Fit verification: The dimensions and wire configuration must be verified against the source holder to ensure proper seating.
Follow these steps to safely install and operate the tungsten basket heater in a vacuum evaporation system. Verify electrical and dimensional compatibility before energizing.
Required Equipment: Vacuum deposition system, Power supply
- Verify geometry
Confirm that the basket heater's dimensions and wire configuration match the source holder specifications. - Check electrical rating
Verify that the power supply can deliver the required voltage, current, and power without exceeding the heater's ratings. - Install heater
Place the basket heater securely into the source holder ensuring proper electrical contact. - Evacuate chamber
Evacuate the deposition chamber to the required vacuum level before applying power. - Energize and heat
Gradually apply power to the heater to reach the desired evaporation temperature.
What are the electrical and thermal limits of the Atomfair tungsten basket heater with 3 wires x 0.025 in DIA?
The heater is rated at 4.22 V, 43 A, and 181 W, with a maximum operating temperature of 1800 °C. These specifications must be matched to the evaporation power supply to avoid under- or over-driving the basket.
How do I confirm physical fit of this 5-coil tungsten basket heater in my existing source holder?
The basket has an overall length of 3.5 in, height of 3/4 in, and an inner diameter of 5/16 in. Verify that your source holder's electrode spacing and cavity dimensions accommodate these values, particularly the ID for crucible or rod placement.
What package options are available for this tungsten basket heater and how do they affect procurement?
The heater is offered in 5/PKG and 10/PKG package formats. Selecting the appropriate package size depends on your anticipated replacement frequency and batch processing needs; both options use the same 3-wire, 0.025 in diameter construction.
The AF-BM-L-TBH0-B002 tungsten basket heater is rated for 1800 °C operation at 4.22 V, 43 A, and 181 W, with a 3-wire by 0.025 in diameter construction and 3.5 in L x 3/4 in H x 5/16 in ID geometry that defines its application fit for vacuum evaporation source heating.
Positive
- High-temperature evaporation capability: Rated for 1800 °C maximum temperature, this basket heater supports demanding vacuum evaporation workflows that require high thermal output.
- Specified electrical loading for supply matching: The defined 4.22 V, 43 A, and 181 W ratings provide a clear reference for confirming power-supply compatibility and avoiding over/under-driving the filament.
Trade-offs
- Low-voltage, high-current supply requirement: The low voltage (4.22 V) and high current (43 A) demand a power supply capable of delivering significant current at low voltage, which may require specialized low-voltage, high-current DC sources.
- Strict dimensional fit verification needed: The exact 3.5 in L x 3/4 in H x 5/16 in ID geometry must be verified against the source holder and evaporation fixture to ensure proper seating and electrical contact, as any mismatch compromises performance.
