What is a thick film heater?

Thick film heater is a type of heating element made by applying a layer of resistive material onto a ceramic or metal substrate. This resistive material is typically a metal oxide or similar compound, which has high electrical resistance and can generate heat when an electric current passes through it.

The term "thick film" refers to the process used to create the heater, where the resistive layer is deposited in a relatively thick layer, typically ranging from a few micrometers to a few hundred micrometers in thickness. This layer is usually printed or screen-printed onto the substrate.

Key characteristics of thick film heaters:

• Compact and efficient: They are often used in applications where space is limited and efficiency is crucial.
• Precise temperature control: Because of the nature of the resistive material, these heaters can offer precise temperature regulation.
• Durability: Thick film heaters are resistant to wear and environmental factors, making them long-lasting.
• Versatile: They can be designed in various shapes and sizes, making them suitable for different applications, such as in industrial, automotive, or consumer electronics.
