What are the classifications of board-to-board connectors?
Board-to-board connectors are classified in a variety of ways, and can be divided into the following types according to their dimensions, hole diameter, pin cross-sectional shape and material, socket molding size and material, application field, shielding design, insulation material, etc
1.HUB connector: The HUB connector is a type of board-to-board connection with a typical structure of a D-Sub9 pin connector. This type of connector is commonly used for data, audio, and display connections in PCs, and is one of the first popular board-to-board connectors.
2.SMT connector: SMT connector is named because it is suitable for SMT automatic labeling, and has the advantages of many times of plugging and unplugging, automatic plugging and dialing, firm connection and easy assembly.
3.BGA connector: With the development of Intel, the chip area continues to increase, and the CPU processor (CPU) chip has also begun to integrate various functions such as graphics card core memory controller and PCI-E slot interface, but the volume has not increased much, and the installation position on the motherboard is more precious. In order not to take up too much space, but also to be in direct contact with the chip for the best electrical performance, BGA connectors are born.
4.CSP connector: CSP is a chip-scale package, which is a form of electronic packaging. CSP connectors are smaller and thinner than previous connectors.
5.FFC FFP Connector: A flexible circuit connector (FFC FFP) is a flexible circuit with the characteristics of being thin and narrow, and is commonly used for the establishment and expansion of circuits in electronic devices.
6.High-speed connectors: With the development of technology, many high-speed board-to-board connectors have emerged to meet the requirements of high data transfer rates.
7.Board-to-board connectors with shielded design: Shielded design board-to-board connectors are mainly used in high-precision, high-stability electronic devices. In addition, according to the different mating methods, board-to-board connectors can also be divided into lock-mating, butt-mating, butt-locking, diagonal connectors and other types. These classifications are based on different characteristics, and the specific classification method used depends on the actual needs.
