The tungsten evaporation boat must be stored in a dry, inert atmosphere to prevent surface oxidation that can degrade resistive heating performance. Mechanical deformation of the thin 0.2 mm wall during handling or installation can cause uneven heating and premature failure.
- Oxidation Sensitivity: Exposure to ambient humidity and oxygen at elevated storage temperatures can form tungsten oxide layers that increase electrical contact resistance.
- Mechanical Integrity: The 0.2 mm thickness makes the boat susceptible to permanent distortion if clamped or mounted with excessive force.
This procedure describes the safe mounting and electrical connection of a straight-type tungsten evaporation boat in a vacuum deposition system. Proper alignment and torque control are critical to avoid mechanical stress and ensure uniform heating.
Required Equipment: Torque screwdriver with calibrated bit, Vacuum deposition system with compatible power supply
- Inspect boat for damage
Visually examine the boat for cracks, dents, or surface discoloration before installation. - Mount boat in source holder
Position the boat flat in the source holder clamps and tighten the screws to the manufacturer's specified torque to avoid distortion. - Connect power supply leads
Attach the power supply cables to the holder terminals, ensuring clean metal-to-metal contact for low resistance. - Verify electrical ratings
Confirm the power supply output does not exceed 1.47 V, 204 A, or 300 W to prevent overheating. - Evacuate chamber
Pump the deposition chamber to the required vacuum level before applying power to avoid arc discharge. - Ramp temperature gradually
Increase the power slowly to reach the target evaporation temperature, monitoring for hot spots or glow discharge.
How does the tub capacity of 1.2 cc relate to the maximum temperature rating of 1200°C for this tungsten evaporation boat?
The 1.2 cc tub capacity defines the maximum volume of source material that can be loaded into the flat tub, while the 1200°C maximum temperature rating is an independent operational limit for the tungsten boat itself. Both parameters must be matched to the evaporation process: the tub capacity ensures sufficient material for deposition, and the temperature rating must exceed the required evaporation temperature of the source material.
What dimensional and electrical parameters must be verified before integrating this straight-type tungsten evaporation boat into a vacuum deposition system?
Before integration, confirm the overall dimensions (0.2 mm thickness, 20 mm width, 100 mm length), tub geometry (flat tub with 40 mm length, 2.5 mm depth, 1.2 cc capacity), and electrical ratings (1.47 V, 204 A, 300 W) against the evaporation source holder and resistive-heating power supply. The product selection notes explicitly require matching these parameters to ensure proper fit and electrical compatibility.
What are the electrical power requirements for operating this tungsten evaporation boat at its maximum temperature of 1200°C?
The boat requires a power supply capable of delivering 1.47 V, 204 A, and 300 W to reach its maximum rated temperature of 1200°C. These values are specified as the electrical rating for this resistive-heating configuration and must be matched to the available power supply before ordering.
The Atomfair tungsten evaporation boat (straight type, flat tub, 0.2x20x100 mm) provides a defined resistive-heating source with 1.2 cc tub capacity and 1200°C maximum temperature, requiring careful electrical and dimensional matching to the existing evaporation system.
Positive
- Tungsten construction for high-temperature stability: Tungsten material supports resistive heating up to 1200°C with defined electrical ratings (1.47 V, 204 A, 300 W), enabling reliable evaporation of source materials under vacuum.
- Precise geometry and tub capacity: Straight type with flat tub of 40 mm length, 2.5 mm depth, and 1.2 cc capacity allows accurate source loading volume matching and dimensional compatibility with evaporation source holders.
Trade-offs
- Electrical rating matching required: The specified voltage (1.47 V), current (204 A), and power (300 W) must be precisely matched to the resistive-heating power supply to avoid underperformance or component damage.
- Dimensional compatibility with holders: Boat dimensions (0.2 mm thickness, 20 mm width, 100 mm length) and flat tub geometry must be confirmed compatible with the existing evaporation source holder before installation to ensure proper fit and electrical contact.
