Polyimide/Kapton Heaters Introduction:
Polyimide/kapton heaters, known for its space-grade quality, is a lightweight film renowned for its resilience in extreme temperatures, retaining its mechanical, chemical, and electrical properties. Its resistance to moisture renders it particularly advantageous in environments of high humidity, wash-down zones, and areas subject to sterilization.
Polyimide/kapton heaters excel in rapid heat transfer. Their slim, lightweight design facilitates intimate thermal contact, ensuring superior heat transfer efficiency and output. This translates into quicker warm-up cycles and extended operational lifespans.
Technical Parameters:
1.Installment methods: pressure-sensitive adhesive, add positioning holes.
2.Flexibility, it can be wound and curved with the minimum curve radius about 0.2 mm.
3.The heater can be manufactured into any shape and also pierced with holes of any shape in the middle, degassing holes are allowed.
4.The heater can designed and divided into multi-zones with different wattages and temperature.
5.Polyimide is waterproof with excellent oily dirty and radiation resistant properties, and applicable in vacuum environments.
6.The heater can withstand a high temperature up to 150°C for long-time operation.
7.The heater can be integrated with sensors, limiters, and thermal fuses to allow control and operation in a wide range of temperatures.
8.Any double-sided backing adhesive can be applied to the heated products.
Applications:
Polyimide heaters are ideal for applications in extreme temperatures, with a working temperature range spanning from -40°C to 200°C. And applied in the following fields.
Medical Devices: Employed in diagnostic equipment, surgical instruments, and laboratory apparatus for precise and efficient heating.
Electronics Manufacturing: Utilized in semiconductor processing, PCB production, and component testing for their flexibility and precise heating capabilities.
Automotive: Applied in de-icing systems for windshield wipers, automotive seat heaters, and heating elements for sensors and actuators.
Industrial Processes: Used for tasks such as heating molds, laminating materials, and maintaining consistent temperatures in processing equipment.
Q1: What tests need to be done for the Polyimide Heaters?
A：100% resistance test (E-test optional). Samples & small batches are tested manually by Multimeter or Bridge Tester. Low resistance tester will be set up in mass productions.
Q2：What are the common insulation methods?
A：Add silica glue (black, red, white, transparent) or add a layer of silicone material to cover the solder joints.
Q3: What’s the quickest lead time for Polyimide heater?
A: For samples, standard lead time is 7 working days, expedite lead time is 3-4 days.
For batches, standard lead time is 2-3 weeks.
Q4: Do you have MOQ for samples?
A: No MOQ requirements, even one piece is possible.
Q5: Can the temperature of the heated product be consistent with the dry heating temperature of the heater?
A: The dry heating temperature will be higher, because the heating product will absorb heat, if the temperature is the same, long-term warming will lead to 3M adhesive paper bulge, can not be fully fitted to transfer heat.
Q6: What are the common temperature control methods?
A: 1. Temperature control switch, do not need motherboard control, just select the desired temperature control range of the switch.
2. Adjustable thermostat with thermistor, K-type temperature control probe and other temperature sensors, can set the temperature and long-term constant temperature.
3. Resistance thermostat, by adjusting the resistance of the heater to adjust to several levels of temperature.
Q7: How to match the size of the wire?
A: Match the wire according to the heater current. Such as the heater current is 2.5A, we will use 24AWG wire.
Q8: What reliability tests are done on the heater?
A: Puncture and Insulation Test, Thermal Shock Test, Strain Relief Test, Temperature and Humidity bias Test.
Q9: What are the attention notes when you assemble the heater?
A: 1. It can not use an over-specified voltage to power the heater, and the temperature is adjusted with the voltage, too high temperature is easy to cause the heater to burn.
2. Heater can not tear, dead folding and other destructive actions.
3. High voltage products should be careful not to puncture the protective film to prevent leakage.
4. The assembly must be fitted well, so that the heater can effectively conduct heat and not let it dry heating.
Q10: How to make the heater heat up faster?
A: The power density is related to the heating time. The higher the power density, the faster the heating time.
