Thermal Plate: Temperature Range -20°C to 300°C

Q: What is the maximum temperature a thermal plate can achieve?

Standard thermal plates typically operate up to 300°C, but specialized versions with different materials can reach 500°C or higher for specific applications.

Q: How is temperature uniformity maintained across the plate surface?

Through optimized heating element placement, high-conductivity materials, and sometimes multiple temperature zones with independent control loops.

Component Specifications

Definition

A thermal plate is a precision-engineered component integrated into substrate holders to provide uniform and stable temperature control during manufacturing processes. It utilizes embedded heating/cooling elements and temperature sensors to maintain specific thermal conditions required for substrate processing, ensuring consistent material properties and dimensional stability.

Working Principle

Operates through conductive heat transfer using integrated resistive heating elements or fluid channels (for liquid cooling/heating). Temperature sensors provide feedback to a PID controller that adjusts power input or fluid flow to maintain setpoint temperature with minimal deviation across the plate surface.

Materials

Typically aluminum 6061-T6 or copper C11000 for optimal thermal conductivity; sometimes stainless steel 316L for corrosive environments. Surface may have nickel plating or anodized coating. Heating elements: Kanthal A-1 wire or etched foil elements. Insulation: ceramic fiber or mica sheets.
