Polyimide Heaters: Advanced Solutions for Flexible PCB Production


Polyimide heaters, commonly referred to as Kapton heaters, are cutting-edge polymer film heaters that have gained widespread popularity in the production of flexible printed circuit boards (PCBs). Their remarkable features and performance make them an indispensable tool in various industries. In this comprehensive article, we will delve into the intricacies of polyimide heaters, exploring their unique properties, benefits, customization options, and applications.

Knowing the Excellence of Polyimide Heaters

Polyimide heaters exhibit a host of exceptional qualities that make them stand out in the field. The polyimide material, known for its outstanding tensile strength, tear resistance, and dimensional stability, ensures the longevity and durability of the heaters. Moreover, in vacuum environments, polyimide heaters boast low outgassing properties, ensuring reliable performance even in challenging conditions.

The remarkable resistance of polyimide heaters extends beyond mechanical properties. These heaters demonstrate excellent resistance to radiation, fungus, and a wide range of substances. This feature contributes to their versatility and suitability for applications in diverse industries. From medical and maternal and child sectors to adult, beauty, and automotive industries, polyimide heaters have found their way into a multitude of cutting-edge applications.

Etched Foil Element Technology and Superior Heat Transfer

Polyimide heaters owe their superior performance to the advanced technology employed in their construction. The etched foil element, created using state-of-the-art photo-imaging techniques, ensures precise circuit repeatability, resulting in consistent and reliable performance. The carefully designed circuitry guarantees excellent heat transfer across the heater, leading to optimal efficiency and energy savings.

The use of etched foil elements offers an added advantage by reducing production costs. With consistent circuit repeatability, manufacturers can achieve higher yields, minimize errors, and streamline their production processes. These benefits contribute to the cost-effectiveness of polyimide heaters, making them an attractive option for various industries.

Customization: Tailoring Polyimide Heaters to Your Needs

One of the remarkable aspects of polyimide heaters is their versatility in customization. Manufacturers can fine-tune various parameters to meet specific requirements and applications. Here are some basic parameters of polyimide heater.


Heating Material

Polyimide heaters can be designed to accommodate different parameters such as 25um PI +25um adhesive or 50um PI+25um adhesive, allowing for precise control of temperature and performance characteristics.

Adhesive tape

Polyimide heaters can be designed with various adhesive options for easy installation and reliable bonding to different substrates. Common materials are 3M468, 3M467 and Crown 513, 3M9080A, 3M9460, 3M9448, Tesa8853, Tesa8854, 3M9077 are also optional if you have such requirements.


The operating temperature of polyimide heaters are range from -40oC to 200oC, <=150oC (continuous).

Voltage and Electrical Resistance

By adjusting the electrical properties, the voltage of polyimide heaters can be customized from 3.7V~400V.

Power Consumption

The power consumption of polyimide heaters can be fine-tuned to achieve energy efficiency without compromising on performance.

Thickness, Size, and Shape

Manufacturers have the flexibility to customize the physical dimensions of the heaters, catering to a wide range of design constraints and space limitations.
