The problem of low characteristic impedance and high return loss in the signal transmission process of the waterproof type-c base is essentially a problem of impedance discontinuity. According to the results of the simulation test, it was found that the structural issues at the connection between the male and female connectors of the connector caused abnormal signal transmission. Therefore, optimizing the structure of male and female contact parts of electrical connectors is the key to solving the Signal integrity problem of electrical connectors. Due to the precise correlation between the characteristic impedance of the connecting line and the capacitance reactance and inductance reactance, it is necessary to increase the characteristic impedance value of the type-c base in the following two ways.

The simulation data of characteristic impedance, insertion loss, return loss, serial loss and other factors can be obtained from the simulation test of waterproof type-c bus base. After the full analysis of the results, it is found that the main reason for the Signal integrity problem of connector bus base is that the fluctuation of characteristic impedance is too large, the smaller value is too small, and the return loss is too large. Therefore, when optimizing the waterproof type-c base, we can focus on optimizing these two aspects.

The main raw materials for the waterproof type-c base are mostly imported high conductivity copper. All purchased materials comply with RoHS environmental standards, using high-performance high conductivity copper (C7025 or C18400) and LCP plastic material that can withstand high temperatures above 260 degrees Celsius. It can withstand 500V high voltage, excessive current, and high product accuracy. We have personnel, equipment, and technical capabilities that are fully independent in high-speed stamping and injection molding production of components, providing strong assurance for product assembly and quality control. Our products are widely used in mobile power supplies, car chargers, computer motherboards, instrument testing equipment, electrical lighting facilities, computer networks, digital set-top boxes, televisions, amplifiers, Bluetooth, MP3, MP4, and other systems.

The waterproof type-c motherboard has appearance and technical advantages such as a thinner design, faster transmission speed (10Gbps), and stronger power transmission (100W). Therefore, it has been favored by the industry since its launch. More and more electronic products are equipped with USB type C and USB PD ports, and their appearance is increasingly seen on the tail plugs of handheld computers, laptops, mobile power supplies, and drones.

Kind reminder: One method is to increase the inductive reactance by changing the parameters that affect the inductive reactance of the type-c bus base; The second method is to reduce the capacitance reactance by changing the parameters that affect the capacitance reactance of the base. Considering that the inductance is mainly affected by the distance between transmission lines, if we want to optimize the parameters that affect the inductance, we need to change the distance between lines, which will greatly change the model of the type-c mother base and cause more unexpected problems for the electrical connector. Therefore, when optimizing type-C motherboards in practice, people should consider many issues comprehensively, otherwise there will be situations where one considers one and loses the other.
