Adhesive tape (Chukoh tape)
Radiation heat dissipation sheet PAL-350A
- Adhesive tape (Chukoh tape)
- Aluminum film material
overview
This tape is made of aluminum film with high thermal conductivity coated with heat-dissipating paint with high emissivity. It converts heat into infrared rays and dissipates it.
Applications
・Heat dissipation for heat-generating components (IC chips, diodes) and housings
・Electromagnetic wave shielding
Features
● By mixing fluoroplastic, it has Weatherability.
●By sticking it directly to a heating element, it can provide a heat diffusion effect through radiant heat dissipation.
●Since the total thickness is thin at approximately 110 μm, it can be used in places where space is limited or where lightweight is required.
●At high frequencies (@1GHz to 6GHz), there is an attenuation effect of approximately 50dB.
●It is also possible to punch out specified shapes.
structure
Electromagnetic wave shielding effect (1GHz to 6GHz)
● Since the base material is aluminum film, it provides a certain level of electromagnetic wave shielding effect.
*Measured using the KEC method

Heat dissipation effect
[1] When a 50mm x 50mm radiation heat dissipation sheet PAL-350A was applied, the heat dissipation effect was approximately 38°C.
Test method: Treat the heating element as an IC chip and measure the temperature change of the heating element after 10 minutes
Heat dissipation effect
[2] The larger the size of the PAL350A radiation heat dissipation sheet used, the greater the heat dissipation effect.

Heat dissipation effect
[3] The temperature of the heating element will change depending on the dimensions of the radiant heat dissipation sheet PAL-350A.
Test method: Measure the dimensions of the radiation heat dissipation sheet PAL-350A and the temperature of the heating element after 10 minutes
