This tungsten evaporation boat is a high-temperature resistive-heating component that must be stored in a dry, inert atmosphere to prevent surface oxidation. The boat's thin 0.3 mm wall thickness is susceptible to mechanical deformation if mishandled or improperly clamped.
- Oxidation Sensitivity: Exposure to ambient moisture or oxygen at elevated temperatures can form tungsten oxides that reduce electrical conductivity and increase brittleness.
- Mechanical Handling Constraint: The 0.3 mm thickness requires careful handling with clean, non-marring tools to avoid bending or cracking the boat walls.
- Electrical Overload Risk: Exceeding the rated 2.84 V, 194 A, or 551 W can cause localized melting or catastrophic failure of the boat during operation.
- Thermal Cycling Constraint: Rapid thermal cycling above 1800 °C may induce stress fractures due to differential expansion between the boat and clamped contacts.
This procedure covers the safe installation and initial operation of a straight-type tungsten evaporation boat in a vacuum deposition system. Proper electrical matching and mechanical alignment are critical to prevent premature failure.
Required Equipment: Clean, non-marring tweezers or vacuum-compatible handling tool, Resistive-heating power supply capable of 2.84 V and 194 A, Vacuum deposition chamber with compatible source holder
- Inspect the boat
Inspect the tungsten boat for any visible cracks, bends, or surface contamination before installation. - Mount the boat
Mount the boat securely into the evaporation source holder, ensuring the flat tub faces upward and the clamping contacts align with the boat's flat ends. - Connect the power supply
Connect the power supply leads to the source holder terminals, verifying that the voltage and current ratings do not exceed 2.84 V and 194 A. - Load the evaporation material
Load the evaporation material into the tub cavity, filling no more than the 0.2 cc capacity to avoid overflow during heating. - Evacuate the chamber
Evacuate the deposition chamber to the required vacuum level before applying any power to the boat. - Ramp the power gradually
Ramp the power supply output gradually to the target 551 W, monitoring the boat temperature to stay below 1800 °C. - Allow the boat to cool
Allow the boat to cool completely under vacuum before venting the chamber to prevent oxidation of the hot tungsten surface.
How do the electrical ratings (2.84 V, 194 A, 551 W) constrain the choice of power supply for this tungsten evaporation boat?
The boat requires a power supply capable of delivering 2.84 V at 194 A to achieve 551 W. These values must be matched to the resistive-heating power supply before ordering to ensure proper heating and avoid under- or over-powering, as stated in the product specifications.
What are the critical dimensional parameters to verify when integrating this straight-type flat tub evaporation boat into an existing vacuum deposition system?
The boat dimensions are 0.3 mm thickness, 7 mm width, 100 mm length, with a tub length of 40 mm, depth 1.5 mm, and capacity 0.2 cc. These must be confirmed against the evaporation source holder geometry and tub volume requirements before installation.
What is the maximum temperature rating of this tungsten evaporation boat and how does it influence process compatibility?
The maximum temperature is 1800 °C. This rating supports temperature-limit matching with the selected evaporation process, ensuring the boat can withstand the required thermal conditions without degradation.
This tungsten straight-type evaporation boat (0.3x7x100 mm, 0.2 cc flat tub) offers a defined geometry and electrical ratings (2.84 V, 194 A, 551 W) for resistive-heating vacuum deposition, supporting up to 1800 °C. Its flat tub configuration and specified dimensions require precise matching with the source holder and power supply, making it a specialized component for controlled evaporation processes.
Positive
- Tungsten construction for high-temperature resistive heating: Tungsten is selected for its refractory properties, enabling a maximum operating temperature of 1800 °C suitable for evaporating a wide range of materials in vacuum deposition.
- Defined electrical and dimensional parameters: Explicit voltage (2.84 V), current (194 A), and power (551 W) ratings, along with boat dimensions (0.3x7x100 mm) and tub capacity (0.2 cc), allow direct matching with power supply and source holder specifications.
Trade-offs
- Requires precise power supply matching: The boat's electrical rating (2.84 V, 194 A, 551 W) must be exactly matched to the resistive-heating power supply; deviations may cause inadequate heating or damage.
- Fixed tub capacity limits source material volume: The 0.2 cc flat tub capacity imposes a strict limit on the amount of evaporation material that can be loaded, requiring careful process planning for deposition runs.
