In the construction of smart homes, industrial Internet of Things (IIoT), and 5G base stations, high-performance routers are key nodes that support massive data transmission and low latency communication. The complexity of its application scenarios has raised higher requirements for the stability, heat dissipation efficiency, and electromagnetic compatibility of devices.
Internal structure diagram of router
shell structure
Lightweight plastic or metal casing should balance electromagnetic shielding (EMI) and environmental protection.
Internal PCB components
Integrate the main control chip, RF module, memory, etc., and avoid moisture, corrosion, and dust intrusion.
Thermal Management System
Equipped with heat sinks, fans, or thermal interface materials for high-performance chips such as 5G modules and CPUs
Key application points of adhesives
Shell sealing and fixation
Traditional screw fixation may create gaps, causing dust and moisture to enter and affect internal circuits. Sealing glue can achieve seamless sealing, enhance protection, and reduce weight.
thermal management
Chip heating can cause performance degradation or even damage, and the adhesive needs to have both adhesion and high thermal conductivity to quickly conduct heat to the heat dissipation module.
conformal coating
The surface coating of PCB can resist short circuits and corrosion caused by humid environments, extending equipment life.
