PCB News - The development of mobile phone electronic connectors

Mobile phones are the most popular digital electronic products today. Electronic connectors are important electronic components in mobile phones. The quality of mobile phone electronic connectors is directly related to the quality of the mobile phone. Most of the quality problems of mobile phones are mostly related to electronic connectors. The types of electronic connectors used in mobile phones vary slightly according to their products. The average number used is about 5-9. The product types can be divided into internal FPC electronic connectors and board-to-board electronic connectors, and external Connected I/O electronic connector, as well as battery, SIM card electronic connector and pogo pin probe electronic connector, etc.

1. FPC electronic connector

The FPC electronic connector is used to connect the LCD display to the drive circuit (PCB). As the LCD driver is integrated into the LCD device, the number of pins of the FPC is reduced accordingly. Future FPC electronic connectors are expected to be integrated with other mobile phone components on the frame of the mobile phone or its LCD module.

2. Board-to-board electronic connectors

The development trend of board-to-board electronic connectors in mobile phones is that the pin spacing and height are getting smaller and smaller, and the subsequent requirements for height are lower and have a shielding effect.

3. I/O electronic connector

The I/O electronic connector is one of the most important access channels in mobile phones, including the connection of the power supply and the signal. The size reduction and product standardization will be the main direction of future development. Nowadays, circular and MiniUSB electronic connectors are more commonly used. MicroUSB electronic connectors for mobile phones have gradually formed a standardized development under the promotion of the European Union and the GSM Association. In the future, I/O electronic connectors are required to be thinner and waterproof. Wait.

4. Card electronic connector

The card electronic connector is mainly based on the 6pin SIM card electronic connector and the T-flash electronic connector. The future development direction is mainly to improve the shielding function and thickness of the SIM card electronic connector. At the same time, the card electronic connector product is oriented to multi-function Development, the market has begun to popularize SIM card electronic connector + T-flash electronic connector two-in-one products.

5. Battery electronic connector

Battery electronic connectors can be divided into shrapnel type and guillotine type. The technical trends of battery electronic connectors are mainly miniaturization, new battery interface, low contact impedance and high connection reliability.

6. Pogo pin probe electronic connector

The pogopin probe electronic connector is a new type of electronic connector. Because of its more refined appearance and more precise contacts, it has been widely used in mobile phones and has become the new favorite of mobile phone electronic connectors. Pogo pin probe electronic connection In the future, the mobile phone will develop in the direction of finer, more stable, and more functional.

The above is an introduction to the internal FPC electronic connector, board-to-board electronic connector, external I/O electronic connector, battery, SIM card electronic connector, and pogo pin probe electronic connector.
