Core PCBA assembly for network switching equipment, supporting high-density layout of Gigabit/10 Gigabit ports and data exchange processing. As the core node of the local area network, it is responsible for efficient forwarding and priority scheduling of multi-terminal data, and is a key component for enterprise and computer room network construction. Relying on mature mixed assembly technology of DIP insertion and placement, we achieve precise soldering of ports and low-latency signal transmission, with high scalability and anti-interference, adapting to the production of enterprise-level switches and industrial-grade switching equipment.
