Characteristics Of Heat Transfer Film

Taizhou Gete Color Printing is a heat transfer film and label supplier as well as a designated printing trademark unit in Taizhou city, striving to provide customers with the best quality services.



JRF graphite heat transfer film
JRF thermal conductive graphite film is also called mobile phone thermal conductive graphite film (the thermal conductive film is also called as heat sink film and heat sink). It is a new type of heat conductive heat sink material, with unique grain orientation, uniform heat conduction in two directions, sheet-like The structure can be well adapted to any surface, shielding heat sources and components while improving the performance of consumer electronics. Experts believe that the reason why it can be designed as a JRF graphite heat sink is mainly to use the plasticity of graphite to make graphite material into a thin sheet like a sticker and let it be attached to the circuit board inside the mobile phone. Not only can block the contact between the originals, but also play a certain role in earthquake resistance.
JRF graphite thermal film application
According to the disassembly of Xiaomi mobile phones, professionals have explored the internal structure of Xiaomi mobile phones, and have also seen two JRF thermally conductive graphite films completely. Hereinafter referred to as graphite heat sink. Although I have seen the graphite heat sink and the place where the graphite heat sink exists, but what exactly is a heat dissipation principle, Xiaomi experts introduce to us:
The first graphite heat sink between the CPU chip and the middle layer
One of the heating sources of Xiaomi mobile phones is the CPU and Flash chip. Therefore, a “7” graphite heat sink is attached to the packaging layer of these chips. The other side of the heat sink will be attached in the middle of the fuselage. Above the metal plate. The other large graphite heat sink is attached to the other side of the metal plate in the middle of the Xiaomi phone, which corresponds to the rear of the screen.
The second graphite heat sink between the screen and the middle layer
When the phone is not disassembled, you can see that the heat behind the screen and the CPU / Flash will be transferred to each other through the middle metal layer, so that the heat can be evenly distributed and the heat is dissipated through the air flow. It is said that part of the heat of Xiaomi's mobile phone will assist the heat dissipation through the LCD side. In addition, the side of the back cover of the mobile phone is another heat dissipation surface.
The experts concluded that the Xiaomi mobile phone using graphite heat sink can control the heat generation to a reasonable level. The graphite heat sink for Xiaomi mobile phones is JRF thermal graphite film-in fact, it plays a role in heat conduction and spreads the heat evenly, indirectly, it also acts as a heat sink. That's why we can control the Qualcomm MSM8260 electric tiger.
