Wave Type Tungsten Heater
1. What Is a Wave Type Tungsten Heater?
A wave type tungsten heater is a tungsten heating element formed by bending high-purity tungsten wire or multi-strand twisted tungsten wire into a continuous wave-like structure. It is also referred to as a wave-shaped tungsten heater.
2. Advantages of CTIA’s Wave Type Tungsten Heater
(1) Multi-point uniform evaporation: Multiple evenly spaced wave peaks generate multiple evaporation points along a unit length. Compared with single peak tungsten heaters, it provides a wider coverage area and more uniform evaporation.
(2) High material loading capacity: The wave peak and valley structure effectively accommodates evaporation materials such as aluminum wire and metal particles, increasing contact area and reducing material slippage.
(3) Stable material retention and evaporation: Continuous wave valleys help stabilize molten metal positioning, reducing evaporation inconsistency caused by material flow.
(4) Excellent thermal stability: The wave structure provides mechanical buffering, reducing thermal expansion stress and minimizing deformation or fracture during repeated heating cycles.
3. Applications of CTIA’s Wave Type Tungsten Heater
(1) Large-area precision optical filters: Used in the production of high-precision optical filters, ensuring uniform thickness and consistent film structure during Physical Vapor Deposition (PVD) processes.
(2) Flexible display manufacturing: Used for metal electrode deposition in Organic Light-Emitting Diode (OLED) devices, providing stable evaporation flux, reducing local overheating, and protecting organic layer integrity.
(3) High-precision electronic thin films: Used in thin-film resistors and sensor chips, ensuring highly uniform composition and microstructure in deposited metal films.
(4) Wide-angle reflector coating: Used for complex curved optical reflectors such as automotive headlamp housings, ensuring uniform coating distribution even at edges and recessed areas.
