     5G smart phones need to run 5G cellular signals on higher millimeter wave frequency and realize large-scale MIMO. The number of antennas is doubled, the RF front-end is increased, and the processor performance is improved. At the same time, due to the need to upgrade to thinner, lighter, large screen folding screen, multi camera high-definition camera and high-power fast charging, the power consumption is sharply increased, about 2.5 times that of 4G mobile phones, The demand for heat dissipation is very strong. How to do a good job in cooling 5G smart phones? We can do this from the following aspects:

CPU kæling:

       In smart phones, intensive application processors, power management circuits and camera modules are the main sources of heat. For example, CPU, GPU and multimedia codec, especially CPU, generate the most heat. When the microprocessor is located in a shell with little ventilation and airtight, how to quickly dissipate heat is a problem that must be solved at present. Thermal designers usually use thermal conductive silicone grease for heat conduction between CPU and radiator. Thermal conductive silicone grease has excellent wetting characteristics and very low thermal resistance, which can quickly transfer chip heat to the radiator to ensure the normal operation of CPU.

PMIC kæling:

      PMIC - power management integrated circuit is also one of the components that generate a lot of heat in smart phones. For thermal management of its power management components such as IC, RAM and image processor, we can use heat conducting gel to conduct heat conduction and heat dissipation. Thermal conductive gel has good thermal conductivity, excellent structural usability and surface mount characteristics of structural parts. It is also suitable for automatic sizing process and widely used in 5G mobile phone.

Rafhlaða kæling:

     The graphite sheet can evenly transfer the heat generated by the CPU / flash memory chip on the PCB of the mobile phone motherboard to the metal support and frame. At the same time, the heat from the high heat CPU chip can quickly spread to the plane of the whole graphite sheet. The graphite sheet on the steel frame on the back of the battery compartment also has the function of evenly distributing heat to the touch screen and emitting battery heat. It solves the problem that it will be hot to use for a long time.

       An excellent thermal conductive silicone grease and heat conductive gel is the key to 5G mobile phone to achieve efficient thermal management. Sinda Thermal has rich experience in the development and production of thermal conductive silicone grease and thermal conductive gel. We can provide customized solutions for heat conduction and heat dissipation.
