Docking Board Function Planning
Common interfaces include Type-C upstream, USB-A downstream, HDMI, RJ45 Ethernet, SD or TF card reader, audio jack and PD charging. We review the port list, controller plan, power path and enclosure constraints before assembly.
High-Speed and Power Design Concerns
Docking station PCBA needs attention to differential-pair routing, impedance, ESD return path, connector placement, thermal behavior and PD power negotiation. These points should be checked before PCB fabrication.
Port-by-Port Testing
Testing can include host recognition, USB data transfer, HDMI display output, Ethernet link, card reader function, audio I/O, charging behavior, connector inspection and aging test by project requirement.
