summary:

The composite resin heating substrate is mainly composed of composite resin substrate to be finished, metal conductive foil resistance layer chip with geometric shape and PI or pet insulation film built in. The chip consists of a resistance layer, a lead end layer and a built-in PI or pet insulating carrier film. The resistance chip is insulated and packaged (cold mounted or heat sealed with PI or pet insulating film), and then the chip assembly is wrapped in the middle of the two-layer composite resin substrate to be finished. After high temperature hot pressing into a whole to form a component.

characteristic:

1. It has high mechanical strength and no deformation. Uniform temperature, good durability and fatigue resistance. Strong UV resistance. Corrosion resistant. Low density and unique It has the advantages of special material designability and so on;
   

   
   

2. The surface heating body has low power density per unit area and uniform surface temperature. The temperature difference between high and low is only 2C. The heating film area accounts for more than 80% of the carrier area On the other hand, the thermal field is more balanced (the temperature difference between high and low is less than 2C. The heater is tested after 20 minutes of power on);
   

   
   

3. Good moisture-proof, anti-corrosion, anti compression, anti-seismic performance, good anti microbial effect and acid resistance. Alkali. Organic solvents and seawater corrosion, UV resistance It can be directly buried in water for a long time (waterproof grade: ipx8 (continuous diving test);
   

   
   

4. The excellent corrosion resistance of the material means that the material has the characteristics of liveliness and non pollution. Its main and auxiliary materials are natural minerals and famous factories at home and abroad The product is stable in performance and odorless in storage and operation. No noise, no harmful substances. Low carbon and environmental protection;
   

   
   

5. Positive temperature coefficient heater. The higher the temperature is, the smaller the power is, so the temperature is easy to control.
