What is the classification and characteristics of board-to-board connectors?

Board-to-board connector, its basic concept refers to connecting different circuit boards together, is currently the strongest connector product in all connector product types with the strongest transmission capacity, mainly used in electric power systems, communication networks, financial manufacturing, elevators, industrial automation, medical equipment, office equipment, home appliances, military manufacturing and other industries. At present, the main board-to-board connector pitch is 0.50mm, 0.60mm, 0.80mm, 1.00mm, 1.25mm, 1.50mm, 2.00mm, 2.50mm, 2.54mm, 3.96mm.

-I. What is the classification and characteristics of board-to-board connectors? Board-to-board connectors, according to the different connection methods between the boards, are divided into different types, each type has its own characteristics.1. Pin and pin/plug pinsPin and pin, also called row of plugs, is the cheaper and most common connection method. Application scenarios: low-end, large-size smart devices, development boards, debugging boards, etc. Advantages: cheap, convenient, hard connection is very solid, strong over-current capability, easy to solder wires and test. Disadvantages: large size, difficult to bend, large spacing, difficult to do hundreds of pin connection (too big). 2. High-end board-to-board plugs are more dense than pins, and are used a lot on compact products. Application scenarios: conventional intelligent hardware products are basically in use, very widely used. Advantages: more pins, small size, 1 cm length can do 40 feet (the same size of the row of plugs can only do less than 20). Disadvantages: expensive, can not be frequently plugged, structural design needs to be fixed. 3. Thickened board-to-board connector board-to-board, board-to-wire, can be detached, can be merged, can be inserted in the row of pins. Usage scenarios: development boards, test boards, large and immobile equipment (such as computer chassis wiring) Advantages: cheap, common, with the use of row of pins, very easy to connect and measure. Disadvantages: large size, not good fixed, not suitable for mass production scenarios.4. FPC connector plug / ZIF connector many intelligent hardware devices, the need to pull the signal from the motherboard, FPC can be bent, small size, shape changeable, it is a good choice. Usage scenarios: connection between motherboard and secondary board, connection between motherboard and peripherals, lines that need to be bent, compact product space. Advantages: both compact and cheap.
