This evaporation boat has a maximum operating temperature of 1200°C and electrical ratings of 1.27 V, 257 A, 326 W. It must be used in a vacuum environment and its dimensions and geometry must be matched to the source holder and power supply.
- Temperature Limit: Maximum operating temperature is 1200°C, which must not be exceeded to prevent boat failure.
- Electrical Ratings: Rated voltage is 1.27 V, current is 257 A, and power is 326 W; these values must be matched by the power supply.
- Operating Environment: The boat is designed for vacuum evaporation systems and must be used under vacuum to avoid oxidation and ensure proper resistive heating.
- Geometry Compatibility: Overall dimensions (0.2 x 25 x 76 mm) and tub geometry (sphere tub, down step 4.1) must be confirmed against the evaporation source holder.
- Material Constraint: Tungsten construction requires careful handling to avoid contamination and mechanical damage before installation.
What are the required voltage, current, and power ratings for this tungsten evaporation boat, and how do they affect power supply selection?
The boat requires 1.27 V, 257 A, and 326 W. These electrical ratings must be matched with the resistive-heating power supply to achieve proper heating. The power supply must be capable of delivering at least 257 A at 1.27 V to reach the rated 326 W output.
How do I verify that the step-type geometry and sphere tub dimensions of this tungsten evaporation boat are compatible with my existing source holder?
The boat has overall dimensions of 0.2 mm thickness, 25 mm width, and 76 mm length, with a tub length of 24 mm, depth of 2.9 mm, and capacity of 0.6 cc. The 'down step 4.1' configuration and sphere tub geometry must match the holder's step and clamping interface. Confirm these dimensions against your source holder's specifications before installation.
What is the maximum operating temperature of this tungsten evaporation boat and how does it constrain the evaporation process?
The boat has a maximum temperature rating of 1200 °C. This limits the evaporation process to materials that vaporize at or below this temperature. The tungsten construction supports resistive heating to this limit, but the power supply must deliver 257 A to maintain the required temperature.
This step-type tungsten evaporation boat with sphere tub (0.2x25x76 mm, 0.6 cc capacity, 1200°C max) is designed for resistive-heating vacuum evaporation, requiring precise power supply matching (1.27V, 257A, 326W) and dimensional compatibility with the source holder.
Positive
- Tungsten construction for high-temperature stability: Tungsten material provides a high melting point and mechanical strength suitable for resistive-heating evaporation sources operating up to 1200°C, ensuring reliable thermal performance under vacuum.
- Precise geometry for source loading compatibility: Defined overall dimensions (0.2x25x76 mm) and tub specifications (24 mm length, 2.9 mm depth, 0.6 cc capacity, sphere tub with down step 4.1) enable accurate dimensional matching with evaporation source holders and consistent source loading volume.
Trade-offs
- Power supply compatibility required: The boat's electrical rating (1.27 V, 257 A, 326 W) must be matched exactly with the available resistive-heating power supply; deviation may cause inadequate heating or damage. This requires pre-order verification of the power supply's output specifications.
- Maximum temperature limit of 1200°C: The 1200°C maximum temperature rating constrains the boat to evaporation processes that do not require higher temperatures; processes exceeding this limit would risk structural failure or degradation of the tungsten element.
