Appearance, development and future trends of board-to-board connectors
In the rapid development of electronic technology, connectors play a vital role as a key component of information transmission and power transmission between electronic devices. Among them, the board-to-board connector as a bridge connecting two printed circuit boards (PCB), its appearance and development not only marks the major progress of electronic connection technology, but also promotes the electronic products to miniaturization, integration, high-speed direction of the key force. This paper will deeply discuss the background, development history and future development trend of board-to-board connector, and reveal its important position in the modern electronics industry.
1. The appearance of board-to-board connectors
Board-to-board connectors appear in the context of the continuous development of electronic equipment to miniaturization, integration and high-speed. With the popularity of electronic products and the acceleration of replacement speed, the connection requirements between circuit boards are becoming higher and higher. Traditional connection methods, such as welding, plugging, etc., have been unable to meet the needs of modern electronic equipment for connection stability, reliability and transmission rate. Therefore, the board-to-board connector came into being and became an important component connecting the two circuit boards.
2. Board to board connector development
Technology improvement:
With the continuous development of science and technology, the technology of board-to-board connectors is also constantly improving. From the initial simple contact connector to the current high-density, high-speed transmission, high-reliability connector, the performance of the board to board connector has been greatly improved.
The continuous optimization of the contact principle, such as the improvement of electrical contact, mechanical contact, geometric contact and surface contact, makes the connection of the connector more stable and reliable.
Variety of types:
According to different classification standards, board-to-board connectors can be divided into many types. According to the structure, it can be divided into needle barrel type and knife mouth type. According to the contact mode, it can be divided into goldfinger type and parallel line type. According to the spacing can be divided into 0.4mm, 0.5mm, 0.635mm, 0.8mm, 1.00mm, 1.27mm and other specifications. This variety of types meets the needs of connectors for different electronic devices.
Application field expansion:
Board-to-board connectors are originally mainly used in high-end fields such as computers and communications. With the progress of technology and the reduction of costs, it has gradually expanded to power systems, financial manufacturing, elevators, industrial automation, medical equipment, office equipment, home appliances, military manufacturing and other industries.
Especially in emerging areas such as smartphones, tablets, and the Internet of Things, board-to-board connectors have played an indispensable role.
Increasing market demand:
With the continuous development of the downstream industry and the increase in market demand, the output and market size of board-to-board connectors are also expanding. According to industry reports, the output and market size of China's board-to-board connectors are growing year by year.
Especially in China, due to its strong production capacity and perfect supply chain system, many internationally renowned connector companies have production bases and research and development centers in China.
The localization process is accelerated:
Driven by the trend of localization, domestic connector manufacturing enterprises have increased research and development investment and introduced advanced production equipment and processes. Domestic connectors are gradually approaching or even surpassing imported connectors in performance, meeting the needs of the domestic high-end market.
The support of the policy also provides a good environment for the development of domestic connectors. The Chinese government has actively promoted the development of the electronics industry and introduced a series of policy measures to encourage domestic substitution.
3. The future development trend of board-to-board connectors
Miniaturization: With the continuous development of electronic devices to miniaturization, the size of board-to-board connectors is also shrinking, the spacing is getting smaller and smaller, the volume is getting smaller and lighter.
High-speed: As the processing speed of electronic devices continues to improve, the transmission rate of board-to-board connectors is also accelerating, requiring higher data transmission capabilities and lower latency.
Integration: board-to-board connectors not only need to achieve signal transmission, but also need to achieve the integration of a variety of functions, such as power supply, optical fiber, coaxial cable, etc., to meet the narrow internal space requirements of electronic devices.
Intelligent: With the continuous development of technologies such as the Internet of Things and artificial intelligence, board-to-board connectors need to have intelligent functions, such as automatic identification and adaptive adjustment, to meet the needs of smart devices.
