Three types of mobile phone connectors

FPC connector is used for LCD display to drive circuit (PCB) connection. With the trend of LCD driver being integrated into LCD device, the number of pins of FPC will be reduced accordingly. Currently, 0.4mm pitch is the main product, 0.3mm pitch The product has also been used in large quantities. There are already related products on the market. In the longer term, FPC connectors will be expected to be integrated with other mobile phone components on the frame of mobile phones or their LCD modules.

At present, mainly based on 0.4mm pitch, it will gradually develop to 0.35mm or even smaller. The development trend of board-to-board connectors in mobile phones is that the pitch and height of pins are getting smaller and smaller, and the subsequent requirements are lower and have a mask effect. . At the same time, the height of the BTB (board-to-board connector) is gradually reduced to 0.9 mm.

The I/O connector is one of the most important access channels in the mobile phone. It uses a circular and MiniUSB connector, which includes the connection of the power supply and the signal. The current mainstream market is 5pin, because each mobile phone manufacturer has its own mobile phone. Solutions, volume reduction and product standardization will be the main directions for future development. The development of the combination of standardization and customization of the Micro USB connector has been made, and the earphone plug-in connector has also developed in the same manner. Later, the connector is required to be thinner, visually and waterproof.
