Funnel-Shaped Tungsten Heater
1.What Is a Funnel-Shaped Tungsten Heater?
A funnel-shaped tungsten heater, also known as a conical tungsten heater, is a tungsten heating element formed from high-purity tungsten wire into a conical spiral structure with a wider top and narrower bottom. It is a geometric configuration in the tungsten heater series and is widely used as a resistive evaporation source in vacuum coating systems.
2.Features of CTIA’s Funnel-Shaped Tungsten Heater
(1) High Material Loading Capacity
Enable direct loading of metal pellets or powder materials through the conical structure, simplifying evaporation source configuration.
(2) Concentrated Thermal Evaporation
Utilize the spiral geometry to concentrate heat toward the central region, enabling uniform multi-directional heating and rapid material melting.
(3) Stable Molten Material Retention
Retain molten metal within the high-temperature core zone through the tightly wound lower structure, ensuring stable evaporation performance.
(4) Strong Structural Stability
Distribute thermal expansion stress along the spiral geometry, reducing sagging or deformation during repeated thermal cycles.
3.Applications of CTIA’s Funnel-Shaped Tungsten Heater
(1) Semiconductor and Electronic Components
Used for metal electrode deposition in microelectronic devices, suitable for evaporating aluminum, silver, copper, and similar materials.
(2) Precision Display Technology
Applied in thin-film deposition for Liquid Crystal Display (LCD) and Organic Light-Emitting Diode (OLED) substrates.
(3) Surface Treatment and Scientific Research
Used for metallization of precision mechanical and ceramic components, as well as micro-quantity material evaporation in laboratory research.
