As the notebook becomes ultra-thin, large-size interfaces such as VGA and RJ45 will naturally be removed, and only the USB-Ch interface is retained, so the expansion docking station accessories market has developed. Charging Head Network recently obtained a USB-C multi-function dock for eeco. This product integrates four most frequently used interfaces: USB-C/A, HDMI, and RJ45. It can meet daily activities such as surfing the Internet, watching videos, and charging and copying files. Let’s disassemble this product and see how the materials are used inside.

charging head network disassembly summary
eeco 1A1C four-in-one multi-function dock comes with USB-C cable, the body case is matte, and the curved surface design on both sides is not difficult to use. The overall product is small and flat, and does not take up desktop space. This dock integrates four most frequently used interfaces: USB-C, USB-A, HDMI, and RJ45, to meet the basic activities of daily office work. Through disassembly, the docking station uses Fuding 4435GYT, Purui PS176HDM DP to HDMI conversion chip, Realtek RTL8153 network bridge chip, VIA VL813-Q7 USB3.0 hub chip and VL101-Q4 DP switching chip, as well as chips from many well-known manufacturers in the industry, including Wanghong 25L512E and MX25L1606E, and the materials are solid. In addition, the internal wire core is injection molded and fixed and protected; all interfaces are soldered by plate vias, which not only reduces the thickness of the product but also enhances firmness; USB-C cables are more durable in bending.
