Single Peak Tungsten Heater
1. What Is a Single Peak Tungsten Heater
A single peak tungsten heater is a tungsten heating element fabricated from high-purity tungsten wire or doped tungsten wire through precision bending and forming processes. It features a centrally raised peaked structure with two terminal leads, designed for localized heating and material evaporation in vacuum deposition.
2. Features of CTIA’s Single Peak Tungsten Heater
(1) High-temperature stability: With a melting point of approximately 3420°C, the structure maintains integrity under high vacuum and high thermal load conditions without melting or structural degradation.
(2) Concentrated thermal field: The single-peak geometry concentrates heat in the central zone, improving localized evaporation efficiency and heating response.
(3) Structural stability: The arched configuration provides mechanical support, reducing deformation at elevated temperatures.
(4) Stable electrical performance: Consistent resistance enables precise control of heating power and evaporation rate.
(5) Low contamination: Low vapor pressure ensures clean operation in high-purity vacuum environments.
3. Applications of CTIA’s Single Peak Tungsten Heater
(1) Vacuum metallization and evaporation: Facilitates the thermal evaporation of metals such as aluminum, chromium, and gold under high-vacuum conditions to ensure stable and uniform thin-film deposition.
(2) Optical thin-film deposition: Utilized in the fabrication of anti-reflection coatings, reflective films, optical filters, and protective layers to achieve precise thickness control and surface uniformity.
(3) Plastic and decorative coating: Used for metallization of polymers such as Polypropylene (PP) and Polycarbonate (PC), including functional and decorative aluminum coatings.
(4) Electronic functional films: Supports the deposition of conductive layers, electrode films, and electromagnetic shielding coatings within electronic device manufacturing.
(5) Laboratory vacuum evaporation: Serves as a evaporation source in Physical Vapor Deposition (PVD) systems for material research and thin-film process development.
