Smart Wearables

Smartwatch

Smartwatches are connected to the Internet to achieve a variety of functions that are not possible with ordinary watches. Smartwatches can be used with smartphones to make and receive phone calls, send and receive e-mails and messages, store and transmit data information, and monitor the user's physical health information. Smartwatches are small in size and light in weight, but in order to realise their multifunctionality, they must be paired with smaller and more sophisticated electronic components with higher performance. Smartwatches are in direct contact with the human body, in order to ensure the comfort and accuracy of the monitoring data, the operating temperature of the smartwatch must be in a suitable range, so the thermal management design should not be ignored.

Smart watches can be applied to thermally conductive interface materials:

① The watch is small in size, the internal gap is uneven, and the chip is more concentrated. Thermally conductive gel (BN-TG350-2, BN-TG350) can be used to dissipate the heat of the watch chip, forming a heat dissipation channel from the watch chip to the heatsink or shell.

②Thermally conductive silicone grease (BN-GC1000, BN-GC2091) can be applied to the surface of the watch chip for heat dissipation. Thermally conductive silicone grease is a thermal conductive compound with good performance, which can be kept in the paste state all the time, and it has good insulating property as well as temperature resistance.

③ Smart watch chip size is small, internal components are concentrated, heat dissipation is large, high elasticity super flexible thermal conductive spacer (BN-FS150US, BN-NS100-PI, BN-FS300-PI) can fully fill the gap between the PCB board and the heat sink or shell, improve the heat dissipation efficiency, so as to make the smart watch maintain its work in a suitable temperature range.

VR Glasses

VR technology is a comprehensive use of computer graphics systems and a variety of reality and control and other interface devices to provide immersion in a computer-generated, interactive three-dimensional environment. In the face of VR glasses users for the picture clarity, the real sense of experience and other higher performance expectations, product designers will consider with higher performance processors, graphics cards and other configurations. To cope with the increase of heat dissipation brought by the hardware upgrade of VR products, Boon Industrial has given more effective heat dissipation solutions.

Thermally conductive interface materials that can be applied to VR glasses:

①Silicone-free thermally conductive spacer (BN-HS100, BN-HS200, BN-HS300) can be used in the gap between PCB components and heat sinks or housings to improve heat transfer efficiency. It is a composite sheet composed of silicone-free resin and thermally conductive filler, which solves the problem of silicone volatilisation from raw materials. Conventional thermally conductive pads have low molecular polysiloxane volatilisation under high temperature conditions, which can contaminate optical and display components and affect image processing and transmission.

②Low volatility thermally conductive spacer (BN-FS300-LV) can be used in the gap between PCB components and heat sinks or housings to improve heat transfer efficiency. With low volatility, D3~D20＜300ppm, it is suitable for optical devices and will not pollute them.

③Thermally conductive gel (BN-TG350-2, BN-TG350, BN-TG350-4) has been kept in paste state after pre-curing, which can be dispensed by automated equipment. Thermally conductive gel has low compression stress and good surface wettability, and can be used directly for CPU heat dissipation.
