Store in a dry, inert atmosphere to prevent tungsten surface oxidation that can degrade resistive heating performance. Handle with clean, powder-free gloves to avoid contaminating the boat surface, which may cause uneven evaporation or arcing under vacuum.
- Oxidation Sensitivity: Exposure to ambient humidity and oxygen at elevated storage temperatures can form tungsten oxide layers, increasing electrical resistance and reducing boat lifetime.
- Contamination Risk: Fingerprint oils or particulate residues on the boat surface can outgas under vacuum, contaminating the deposited film and altering evaporation uniformity.
- Mechanical Integrity: The 0.3 mm wall thickness is susceptible to deformation or cracking if the boat is bent or dropped before installation.
Mount the boat securely in the evaporation source holder, ensuring electrical contacts are clean and tight to minimize contact resistance. Load the evaporation material into the tub cavity without overfilling, then ramp power gradually to the rated 551 W while monitoring vacuum pressure.
Required Equipment: Vacuum deposition system with compatible source holder, Resistive heating power supply rated for 2.84 V and 194 A, Clean, powder-free gloves
- Inspect the boat
Visually confirm the boat has no cracks, bends, or surface contamination before installation. - Mount the boat
Insert the boat into the source holder clamps, centering the tub between the electrodes, and tighten the clamps to secure electrical contact. - Load evaporation material
Place the source material into the tub cavity, filling to no more than 80% of the 0.3 cc capacity to avoid spillage during heating. - Set power supply parameters
Configure the power supply to a maximum of 2.84 V and 194 A, with a ramp rate that prevents thermal shock to the boat. - Evacuate the chamber
Pump the deposition chamber to the required vacuum level before applying any power to the boat. - Ramp power gradually
Increase power slowly to the target 551 W while monitoring the boat temperature and chamber pressure for any sudden outgassing. - Cool and remove the boat
Allow the boat to cool below 100 °C under vacuum before venting the chamber and removing the spent boat for disposal.
How do I verify that this tungsten evaporation boat will fit my existing evaporation source holder?
Confirm overall dimensions (0.3 mm thickness, 8 mm width, 100 mm length), tub length (40 mm), tub depth (1.7 mm), and tub capacity (0.3 cc) against your source holder geometry. The straight type with flat tub configuration must match the holder's mating interface.
What electrical ratings must my power supply meet to safely operate this evaporation boat?
The boat requires 2.84 V, 194 A, and 551 W. These values must be matched with your resistive-heating power supply to ensure proper heating and avoid damage from overvoltage or insufficient current.
What is the maximum temperature this evaporation boat can withstand and how does it affect process selection?
Maximum temperature is 1800 °C. This supports temperature-limit matching with your evaporation process; ensure your process does not exceed this limit to prevent boat failure or material degradation.
Tungsten evaporation boat with straight geometry and flat tub, 0.3x8x100 mm, rated for 1800°C, providing precise dimensional and electrical specifications for vacuum deposition source loading.
Positive
- High-temperature tungsten construction: Tungsten material supports resistive heating up to 1800°C, suitable for evaporation of various metals and dielectrics under vacuum.
- Precise dimensional specifications: Defined 0.3x8x100 mm geometry and 0.3 cc tub capacity enable accurate dimensional matching with evaporation source holders before installation.
Trade-offs
- Minimum order quantity of 5 pieces: MOQ 5 pcs may require inventory planning and is less flexible for single-unit procurement.
- Compatibility verification required: Voltage, current, and power ratings (2.84 V, 194 A, 551 W) must be matched with the resistive-heating power supply, and tub geometry must fit the holder, requiring pre-purchase confirmation.
