Product Description:
Our 18-layer rigid-flex PCBs are better than normal rigid PCBs and simple flexible PCBs, which makes better performance to network infrastructure.
It's made specifically for new-generation network equipment, it also uses sturdy FR4 TG170 rigid material with 4mil flexible FPC. This special hybrid design doesn't need the large connectors, it fits perfectly inside compact, intricately structured routers, switches and core servers.
As the core component of the network system, it can achieve higher circuit integration, faster data transmission speed and longer service life for the equipment that carries critical network services.

Product Advantages:
1. Unmatched Density: This kind of PCB design with 4/4mil precision can achieve the integration of 2x more functional modules in the same footprint, which can reduce the network device size by up to 25% compared to traditional multi-board setups.
2. Dynamic Durability: The rigid parts hold up well under constant vibration inside server cabinets. Meanwhile, the flexible sections can withstand over 10,000 bends. This kind of PCB is a great choice for network gear, as it delivers solid structure and flexible mounting at the same time.
3. Signal Excellence: We use the TG170 FR4 material, and this board can effectively reduce high-frequency signal loss. Combined with ENIG surface treatment, it also maintains stable signal transmission efficiency up to 99.9%, which fully supporting 100G and above high-speed network data transmission.
