As an indispensable part of electronic products, BTB connector has the characteristics of fast and stable transmission function and low loss and high fidelity, and acts as a bridge of communication in electronic circuits. The BTB connector inside the mobile phone mainly plays the role of connecting pcb, module, and motherboard to realize the mechanical and electrical connection. With the advent of the 5G era, the performance upgrade of BTB connectors has become an inevitable trend. In order to adapt to the characteristics of high integration and small pitch in mobile phones, BTB connectors are also developing towards small pitches, multiple pin counts, and high-speed transmission.
Three major performances of BTB connectors: mechanical performance, electrical performance and environmental performance. Mechanical performance refers to the number of insertions and removals, retention force, positive force, durability, vibration and mechanical impact of the BTB connector; electrical performance refers to the requirements of the contact resistance, insulation resistance, and electrical strength of the BTB connector; environmental performance Refers to the temperature and humidity cycle, thermal shock, high temperature resistance, and vibration resistance of BTB connectors.
The transition from 4G to 5G has accelerated the iteration speed of products in the consumer electronics industry. Smart phones, wearable multi-functional modules and high-speed development have promoted the development of BTB connectors. The increase of 5G smart phone functions, plus the fact that each module must be connected to the motherboard to achieve signal transmission, and factors such as high internal integration of the mobile phone, the demand for BTB connectors has greatly increased, while the high-speed high-frequency transmission of BTB connectors It also has higher requirements.
The increase of 5G smart phone cameras will drive the growth of the BTB connector inside the phone to connect the phone camera module. Multi-camera camera technology for smartphones has been fully popularized, and smartphones equipped with three-camera, four-camera, and five-camera cameras have been released one after another. The demand for BTB connectors is also growing. It is expected that a single multi-camera phone can increase by 1-3 pairs BTB connector.
Because the size of the BTB connector can be miniaturized and narrowly spaced, it can also maintain stable transmission capacity, which is suitable for the characteristics of thin and light mobile phones and compact internal space. 5G smart phone RF connection can use BTB connector to connect the antenna and RF front end to strengthen the signal strength. This demand increases the number of BTB connectors inside the phone by 1-2 pairs.
The increase in the market penetration of wearable devices will also drive the growth of BTB connectors. Taking wearable smart watches as an example, display, touch screen, antenna connection, battery connection, microphone connection and other components that need to use the connector, BTB connector The amount can reach 1-3 pairs.
In the manufacture of BTB connectors, qualification certification and testing are required to ensure the quality and performance stability of BTB connectors. For the testing of BTB connectors, a high-current shrapnel microneedle module can be used as the connection module, which can play the role of conducting current, and can maintain stable performance and improve the testing efficiency of BTB connectors. In the 5G era, the demand for BTB connectors is growing rapidly, and the quality of BTB connectors should also be paid attention to. The BTB connector market, which is in an upward cycle, is expected to grow further in the future.
