how does pcb for AR smart glasses work?

AR smart glasses PCB is the core of AR smart glasses, responsible for audio and video acquisition and display processing and other functions.

PCB for AR smart glasses is used to achieve functions such as audio and video acquisition and video display processing. The following is a detailed introduction of the AR smart glasses PCB :

Composition: The PCB of AR smart glasses is composed of a number of components, including Intel Movidius vision processing unit (VPU) and other processing chips, PMIC chips, memory, connection chips, etc.

Manufacturing process: The PCB adopts the mainstream 10-layer second-order design, and adopts advanced technology such as blind buried holes in the manufacturing process, which makes the signal transmission more stable and reduces the space size of the PCB .

Power management: A dedicated PMIC chip is used to power the VPU processing unit. The core power supply voltage of the chip is 0.8V and the maximum load current is 6A, which can meet the high-performance processing requirements of AR smart glasses.

Heat dissipation design: Considering that AR smart glasses need to be worn for a long time, heat dissipation design is very important. The PCB board uses a combination of copper substrate and thermal glue to conduct the heat generated by the chip to the shell to achieve heat dissipation.

Signal transmission: The PCB board realizes the stable transmission of video signals through high-speed signal transmission technology. At the same time, the use of wireless communication technology, such as Bluetooth, WiFi, etc., to achieve wireless connection with external devices.
