This tungsten evaporation boat is a technically constrained consumable for vacuum evaporation processes. Proper selection and matching with the source holder and power supply are critical to prevent operational failure.
- Compatibility Constraint: The boat geometry, tub capacity, and overall dimensions must match the evaporation source holder to ensure proper seating and source loading.
- Electrical Rating Constraint: The voltage, current, and power ratings must be matched with the resistive-heating power supply to avoid overheating or insufficient heating.
- Temperature Limit Constraint: The maximum temperature rating of 1800 °C must be checked against the evaporation process requirements to prevent material degradation.
Confirm the tungsten evaporation boat matches the evaporation source holder and power supply before installation. These steps ensure safe and effective operation in vacuum evaporation processes.
- Confirm Dimensional Compatibility
Confirm the boat material, overall dimensions, tub geometry, and tub capacity against the selected evaporation source holder. - Match Electrical Ratings
Match the voltage, current, and power values with the available resistive-heating power supply before ordering. - Verify Temperature Rating
Verify the maximum temperature rating against the evaporation process temperature requirements.
What are the electrical rating constraints for the Atomfair tungsten step-type evaporation boat with sphere tub?
The boat is rated at 4.96 V, 136 A, and 675 W. These values must be matched against the available resistive-heating power supply before ordering to ensure proper thermal performance and avoid overloading the source holder.
How does the tub geometry of this tungsten evaporation boat affect source loading compatibility?
The boat features a sphere tub with an upper step 5 configuration, a 10 mm tub length, 2 mm tub depth, and 0.1 cc capacity. These parameters must be confirmed against the evaporation source holder to ensure proper fit and sufficient volume for the source material.
What is the maximum operating temperature of this step-type tungsten evaporation boat and how does it influence process selection?
The maximum temperature rating is 1800 °C. This limit supports temperature-limit matching with the selected evaporation process, ensuring the boat can withstand the required thermal conditions without degradation.
This tungsten evaporation boat offers a high maximum temperature of 1800 °C and a precise 0.1 cc tub capacity for controlled evaporation, but requires careful matching of electrical ratings and dimensional compatibility with the power supply and source holder.
Positive
- High-temperature tungsten construction: Tungsten material supports operation up to 1800 °C, enabling high-temperature evaporation processes for refractory materials.
- Precise tub geometry and capacity: The 0.1 cc tub capacity with defined dimensions (10 mm length, 2 mm depth) allows accurate source loading and compatibility with specific evaporation source holders.
Trade-offs
- Strict electrical matching required: The evaporation boat's specific voltage (4.96 V), current (136 A), and power (675 W) ratings must be matched exactly with the resistive-heating power supply, limiting compatibility with non-standard supplies.
- Minimum order quantity constraint: A minimum order quantity of 5 pieces applies, which may be restrictive for small-scale R&D or pilot projects.
