Honflex Electronics, as a large factory manufacturing AR Glasses Transmission Line FPC in China, supports customizable flexible interconnect core components specifically designed for augmented reality (AR) glasses and smart glasses. The "data backbone" capable of connecting various structural components of the glasses links the main control system (SoC/ motherboard) located on one temple to the key components (such as display engine, camera, speaker, microphone, battery, antenna and multiple sensors) distributed on the other temple, frame and optical module.
The team adopted a dynamic flexible design using an ultra-thin multi-layer substrate with a thickness of only 0.17 millimeters or thinner. By bending at a very small bending radius in the bridge area of the nose, they successfully connected the left and right temple legs, achieving simultaneous electrical transmission. For the frequent opening and closing of the temple legs, a reinforced structure design was used to ensure that the hinge or bending area could withstand continuous bending cycles of 100,000 times or up to 500,000 times. It still maintains electrical performance and mechanical integrity.
Inside the temple, high-density irregular precise wiring of six or more layers has been achieved, enabling the high-speed transmission of complex signals such as data, audio, power and control. The antenna traces are directly integrated onto the FPC and installed inside the temple, greatly saving precious internal space.
To address the heat dissipation challenges caused by concentrated heat sources such as the main processor in confined Spaces, we have introduced embedded thermal management technology. To cope with the harsh wearing environment, the AR Glasses Transmission Line FPC has specially adopted a special protective coating to prevent erosion by sweat, corrosion, grease and other contaminants caused by skin contact.
| Parameter | Specification |
| Thickness | ≤0.17 mm (Multiple layers) |
| Line Width | 50 μm |
| Spacing | ~50 μm |
| Environment Resistance | Sweat resistant, corrosion resistant |
| Thermal Performance | Material or structural design increases heat dissipation efficiency by >60% |
| Dynamic Elastic Zone | BBB 100,000 cycles |
The thickness of FPC is less than 0.2mm, and it is extremely light in weight. It can fit the irregular shape of glasses, providing the best wearing comfort for users.
