Single-Strand Tungsten Heater
Single-strand tungsten heater refers to a resistive evaporation source element directly processed from a single high-purity tungsten wire. It is the most fundamental and simplest structural form in the tungsten heater series. Due to its well-defined structure, stable resistance, and fast thermal response, the single-strand tungsten heater is widely used in precision micro-deposition processes in Physical Vapor Deposition (PVD).
The single-strand tungsten heater has low thermal mass and can rapidly reach the preset operating temperature, shortening the preheating cycle and supporting high-frequency cyclic evaporation tasks. The single tungsten wire also provides good processing flexibility, allowing small-angle bending and precise shaping, and can be installed in compact evaporation source spaces. In addition, the gap-free design ensures uniform current density distribution, helping to form a stable linear thermal field and improving film thickness uniformity. For laboratory research or micro-evaporation applications, the tungsten wire heater maintains process performance while offering good cost efficiency.
CTIA’s tungsten wire heater is used in integrated circuit packaging processes for the deposition of precision electrode layers in Micro-Electro-Mechanical Systems (MEMS). It is also applied in the precision optics industry for anti-reflection coating deposition on Liquid Crystal Display (LCD) components and optical lenses. It serves as an evaporation source for gold coating in Scanning Electron Microscope (SEM) sample preparation in scientific research and analysis. It also supports the deposition of biocompatible metal layers or conductive coatings on interventional medical devices in medical device manufacturing, ensuring stable film quality.
