Smart TVs, smart speakers, TV sticks, set-top boxes, wireless data communication devices and video game devices make our life colorful in the environment. However, there are strict thermal management and harsh EMC requirements showed behind these smart devices. Based on these requirements, JONES provides integrated thermal design and EMC solutions for these smart home products. From thermal simulation to various heat-conducting, heat sharing and thermal storage materials to various shielding and wave-absorbing products developed for high-frequency and thin-walled materials, these produces provided can effectively improve the reliability and safety of smart home products.
Synthetic graphite sheet, multilayer graphite & natural graphite
The Vanoc synthetic graphite film adopts the internationally leading processing technology and has remarkable advantages such as high crystallinity and good lattice orientation. The product not only has high thermal conductivity, but also has good anisotropy—Thermal conductivity, in-plane 1800W/m-K, through-plane 15W/m-K. It is a good replacement to traditional heat spreading and thermal interface materials and has higher reliability. As a process-friendly material, Synthetic graphite has been widely usedin smart devices and a lot of wearables as a thermal diffusion material . it has also been widely used in industries with high reliability requirements such as communication equipment and power electronic equipment, as a thermal interface material.
Thermal Pad is a thermal conductive composite material with a certain thermal conductivity and flexibility. It is mainly used for gap filling between semiconductor devices and heat sinks, and improves the transfer efficiency of the heat generated by semiconductorsvduring operation.
Thermal GEL is a kind of thermal conductive composite with a certain fluidity, which can be applied to heat-generating devices by means of dispensing, with higher assembly efficiency and suitable for automated production lines. GEL-state thermal conductive products have lower thermal resistance, better compression set performance, less compressive stress, and are suitable for applications in which different heat-generating devices share a common heatsink.
Wave absorbing rubber
The microwave absorbing rubber sheet is a functional polymer material independently developed by our company. Through adding absorbing particles in the elastomer, microwave absorbing rubber sheet has good electromagnetic wave absorption effect. Formulations are tuned according to the specified frequency ranges from 1 to 40 GHz through independently developed recipe adjustments. Depending on the customer’s specific application scenario, the absorbing materials range offers standard sheet and customized die cut shapes.
Fabric over foam
FOF consists of conductive fabric layer and foam core, which can be processed into various shapes. The compressibility and resilience of foam core can meet the requirements of low sealing force. It is widely used in EMI protection of electronic equipment’s housing and provides EMI shielding at the cabinet gap.
Three-way conductive foam—-Ni-plated PU foam provides good electrical conductivity while maintaining low compressive stress and high deformation characteristics. It is not limited to the outer conductive structure as that of traditional FOF gasket,can be designed according to the application required dimension without affecting the conductivity.
IP protection materials
IP protection rubber gaskets, silicone rubber materials, which provides stable shape retention and seal resilience, as well as good high temperature resistance and weather resistance.
The heat pipe is a kind of heat-conducting material. It makes full use of the heat-conducting principle and the fast heat-transfer properties of the phase-change medium to quickly transfer the heat of the heating object to the outside. Its thermal conductivity of heat pipe exceeds that of any known metal.
Vapor Chamber is a vacuum cavity with a fine structure on the inner wall. The purpose of heat dissipation is achieved through the vaporization and condensation of the cooling liquid in the cavity, which is usually used for electronic products that require a small volume or need to quickly dissipate high heat.
Form in place
FIP conductive rubber gasket (form-in-place) can automatically dispense high-conductivity rubber on metal or plastic substrate to form EMI shielding gasket according to customer’s different design with computer-aided programming dispensing equipment.The gasket is made by filling different conductive particles in a silicone rubber. It has good elasticity and cured at a high temperature to form an electromagnetic and environmental sealing material. Our company can provide FIP materials with different packaging and different hardness according to different shielding performance requirements of customers, and can provide a total solution for conductive FIP products.
