thin film heater

Produktanwendungen:

Portable coffee machine, beauty instrument, medical thermostat, laboratory micro-heating plate, semiconductor dispensing machine, drone battery thermal management, smart wearable device heating components, industrial micro-spraying system.

Core parameters

Power density:
Conventional range: 0.1–1.5 W/cm² (customizable local high power areas, such as sensor heating).
Limit value: 2.0 W/cm² (needs heat dissipation design, such as forced air cooling).
Operating voltage: DC 5V–400V (supports low voltage precision control, such as wearable devices).
Operating temperature: Continuous stability: 50°C–200°C (surface temperature, long-term use).
Short-term peak: 300°C (requires high temperature resistant substrate, such as ceramic).
Heating speed: 5–30 seconds to reach the set temperature (no thermal inertia, response speed is 2–3 times faster than thick film).
Material and structure:
Substrate: Polyimide (PI) flexible film (bendable, curvature radius ≥1mm) or ceramic substrate (aluminum oxide/aluminum nitride).
​​Heating layer: metal (molybdenum, tantalum) or ceramic (titanium nitride) film (thickness 0.1–5μm).
​​Protective layer: SiO₂/Si₃N₄ insulating layer (moisture-resistant and corrosion-resistant).
​​Service life: ≥20,000 hours (no mechanical loss, life is 2–3 times longer than thick film).
​​Customizable: Special-shaped cutting (circular, special-shaped circuit boards), integrated temperature sensor (NTC/PTC).

Wesentliche Vorteile

​​Ultra-thin and flexible: The substrate thickness is 0.05–0.5mm and can fit curved surfaces (such as smart watch straps, medical patches).
​​Precise temperature control: PID algorithm supports ±0.1°C accuracy (suitable for laboratory constant temperature and medical equipment).
​​Quick response: Heating to 100°C within 5 seconds (50% more efficient than traditional heaters).
​​Corrosion resistance:
Ceramic/metal film is acid and alkali resistant (suitable for chemical pipeline heating and marine environment).
​​Lightweight design:
The weight is 60% lighter than thick film heaters, suitable for drones and portable devices.
​​Safe and reliable:
Automatic power off in case of overheating (trigger temperature can be set, such as automatic protection at >250°C).
​​Long life:
No mechanical wear, life is more than 3 times longer than alloy wire heaters.
