Molybdenum Evaporation Boat 0.5×6×100 mm Flat Tub ATOMFAIR®

Store in a dry, inert atmosphere to prevent surface oxidation that can degrade electrical contact resistance. Avoid mechanical deformation of the thin-walled tub geometry, as bending or denting compromises dimensional fit within the evaporation source holder.

• Oxidation Sensitivity: Exposure to ambient humidity and oxygen at elevated storage temperatures may form a molybdenum oxide layer, increasing electrical resistance and reducing heating efficiency.
• Mechanical Integrity: The 0.5 mm thickness and flat tub configuration are susceptible to plastic deformation under clamping forces exceeding the rated source holder specifications.

This procedure covers mounting the boat into a compatible resistive-heating source holder and verifying electrical parameters before first use. Proper alignment and torque application prevent premature failure during vacuum evaporation cycles.

Required Equipment: Torque screwdriver with calibrated bit for source holder terminals, Digital multimeter for resistance check across boat terminals

1. Inspect boat geometry
   Inspect the boat for any visible bending, cracks, or surface discoloration before installation.
2. Mount boat into source holder
   Insert the boat into the source holder clamps, ensuring the flat tub faces upward and the boat is centered along the holder axis.
3. Tighten terminal clamps evenly
   Tighten the terminal clamps to the manufacturer-specified torque using a calibrated screwdriver, applying equal force on both ends to avoid warping.
4. Verify electrical continuity
   Measure resistance across the boat terminals with a multimeter; confirm it matches the expected value for the given material and geometry.
5. Set power supply limits
   Set the power supply voltage to 1.31 V, current limit to 253 A, and power limit to 331 W before energizing the circuit.
6. Perform initial ramp test under vacuum
   Ramp the power gradually under vacuum while monitoring boat temperature with a pyrometer, ensuring it does not exceed 1200 °C.

This molybdenum evaporation boat (0.5x6x100 mm, flat tub, 0.1 cc capacity) is rated for 1200°C and 331 W, requiring precise electrical and dimensional matching with the evaporation source holder and power supply.

Positive

• Molybdenum construction for high-temperature evaporation: Molybdenum material is selected for resistive-heating source geometry and supports a maximum operating temperature of 1200°C, suitable for vacuum evaporation processes requiring thermal stability.
• Defined dimensions for system compatibility: The straight-type geometry with 0.5 mm thickness, 6 mm width, 100 mm length, and 40 mm tub length (0.1 cc capacity) enables dimensional matching with the evaporation source holder before installation.

Trade-offs

• Electrical rating matching required: The boat's voltage (1.31 V), current (253 A), and power (331 W) must be matched to the resistive-heating power supply; mismatch can lead to improper heating or system damage.
• Limited tub capacity constrains source loading: The 0.1 cc tub capacity restricts the volume of evaporation source material that can be loaded, which may require more frequent refills for extended deposition runs.
