With the high requirements for battery life and charging of electronic products such as mobile phones, fast charging will become the mainstream trend in the development of the mobile phone industry. In the process of continuous development towards higher power, new requirements have been put forward for connectors. So how will the technology of connectors be innovated!

At present, people are using smartphones more and more frequently. Therefore, in the current situation where battery space is limited and battery capacity cannot be significantly increased, improving the power and efficiency of chargers and significantly shortening charging time has gradually become a consensus among mobile phone manufacturers. At the same time, the fast charging market has also been promoted to a market with a potential of over 100 million yuan. Minsheng Securities predicts that the overall wired charger market space in 2022 will be 108.1 billion yuan, including 98.6 billion yuan for fast charging, with a CAGR of 40% from 2020 to 22.

In order to alleviate users' charging anxiety, fast charging methods have emerged one after another in the 100W era. Electronic products, mainly mobile phones and computers, have introduced higher power charging configurations, and the 100W level of fast charging is gradually becoming popular.

The increase in power consumption of smartphones and the limited battery capacity of smartphones have also led to the emergence of various fast charging solutions. The charging solution for fast charging has shifted from traditional high-voltage low current and low-voltage high current solutions to a fusion solution of high current and high voltage.

Among them, the improvement of fast charging power is achieved through the collaboration of chargers, data cables, and terminal batteries.

The type-c connector has become the best fast charging standard interface at present. The type-c connector has advantages such as diverse functions, high-speed transmission, easy operation in both directions, and small and slim size. Therefore, the type-c connector has become the best fast charging standard interface at present.

In the process of rapid charging towards higher power, continuous optimization of data cables and interfaces is needed to enable the entire charging process to withstand larger charging currents and voltages. Among them, the type-c connector also needs to undergo process and technical improvements.

Taking the issue of contact impedance as an example, whether the material of the terminals in the type-c connector is made of high conductivity copper, the thickness of the terminal gold plating, the molding process of the terminal plastic, and whether the terminal molding is flat will all affect the contact impedance.

So in addition, what technical difficulties do type-c connectors face and what technological innovations have they made in terms of solutions? What are the downstream manufacturers' requirements for connectors? What are the innovations and technological improvements in magnetic components and semiconductor chips, other than connectors, facing higher charging power?

In order to better provide an offline communication platform for intelligent fast charging related manufacturers, assist them in obtaining new industry trend information, product innovation technologies and solutions, and achieve the upgrading of intelligent fast charging product applications and technologies.

On August 12-13, 2021, BigBit will hold the "2021 China Electronics Hotspot Solution Innovation Summit" in Shenzhen, focusing on key components such as integrated circuits, semiconductors, power devices, magnetic components, connectors, materials, and wires, for the electronic component industry to have a special exchange on the topic of "intelligent fast charging and type-c technology".

At that time, BigBit will collaborate with more than 20 solution providers, 20 well-known experts in the industry, and 80+display manufacturers to explain industry prospects and technical challenges through 8 popular innovation application summits, assisting upstream and downstream industry chain professionals in communication and learning, and jointly exploring the latest market development trends and innovative application solutions.
