With the data provided by the customer, the amount of heat required, size, and materials are considered to meet the requirements of the customer as we design the products. Once completed, the design is handed over to the production department.
Depending on the applications, temperature and reliability are considered.
To produce the base film to which the carbon material is applied, the PET material and PE materials are joined.
Depending on the specification of the desired film, the thickness of the PET and PE layers are adjusted.
The carbon paste, which functions as the actual heat radiator, is applied to the circuit pattern according to the design.
The paste is mainly composed of carbon and silver.
The key in this process is to maintain the consistency of thickness and resistance value.
To form electrodes on the film, silver and copper boosters are synthesized. The key here is the pre-treatment to prevent sparks and ensure insulation.
Successful execution of this process is essential for the safety of the product.
The carbon-coated base film, booster, and the top film composed of PET and PE are joined together by our laminating process.
This process is the key to the insulation and protection from moisture and essential to ensure the integrity of the product and its reliability.
The products that passed the quality control are hardened through the high-temperature aging process to have the booster, and the top/bottom layers fused and optimize the adhesive performance of carbon.
Once the laminating process is over, the film goes through an electrical test and visual inspection to check the distribution of carbon and the conditions of the top and bottom layers.
Once the product passes a visual inspection, a sample from each role is taken to be tested electrically to check the amount of heat emission and electrical resistance, as well as the integrity and safety of the finished product.
