Application

Combo boat components are used in a process called physical vapor deposition (PVD), specifically thermal evaporation. They consist of ceramic boats and tungsten wires. Ceramic evaporation boats are made of materials such as alumina or graphite and are used to hold the material to be evaporated. When the boat is heated, the material changes from a solid to a gas, allowing controlled evaporation. The shape of the boat helps direct the vapor to the substrate for efficient deposition. A tungsten wire is used as a heating coil. It is connected to a power source, and when current passes through it, the wire heats up due to its resistance. The wire has a high melting point and good thermal conductivity, making it suitable for this task. By providing heat, the wire vaporizes the material inside the ceramic boat, thus achieving controlled evaporation.
