The product has four hook feet. When welding, the hook feet are placed in the PCB board and sink by 1.6mm, that is, the lower part of the PCB board sinks by 1.6mm or the broken board sinks by 1.6mm. The interface is an elliptical interface. The tail pins are arranged in a single row, with the pins embedded in the plastic and welded to the PCB SMT board. The exposed copper of the type-c mother tongue is a one-time touch. The tail buckle is connected and fixed to the plastic body to prevent the plastic body from falling out of the hardware shell. The USB Type-C is as lightweight and compact as the Lightning interface in iPhone phones, and can be expanded into three interfaces: power/USB transmission/VGA or HDMI. Through the adapter, it can also be compatible with previous generation interfaces such as USB3.0 and USB2.0. The type-c16p motherboard supports high current charging and data transmission. The material used is a high-strength stainless steel shell, with a plastic body made of environmentally friendly and high-temperature resistant LCP plastic. The tail pins are made of high conductivity copper.
