Get to know connectors--board to board connectors

Basic definition of board to board connector
Board To Board Connectors connect different circuit boards together. Board to board Connectors exist not only to facilitate disassembly, but also as a carrier to provide current and signals to products. It is the connector product with the strongest transmission capacity among all connector product types. It is mainly used in power systems, communication networks, financial manufacturing, elevators, industrial automation, medical equipment, office equipment, home appliances, military manufacturing and other industries.
At present, the main pitches of board to board connectors are 0.50 mm, 0.60 mm, 0.80 mm, 1.00 mm, 1.25 mm, 1.50 mm, 2.00 mm, 2.50 mm, 2.54 mm and 3.96 mm.
Classification and characteristics of Wire To Board Connectors
Board to board connectors are divided into different types according to the different connection methods between circuit boards, and each type has its own characteristics.
1. Pin header/pin header
Pin and female headers, also called headers, are the cheapest and most common connection methods.
Application scenarios: low end, large size smart devices, development boards, debugging boards, etc.
Advantages: cheap, convenient, solid hard connection, strong overcurrent capability, convenient welding and testing.
Disadvantages: Large, not easy to bend, large spacing, difficult to connect hundreds of pins (too big).
2. High end board to board power strip
It is denser than pin headers and is widely used in compact products.
Application scenarios: Basic use of conventional smart hardware products, widely used.
Advantages: large number of pins, small size, 1cm length can make 40 pins (the same size can only make less than 20 pins).
Disadvantages: expensive, cannot be plugged in and out frequently, and the structural design needs to be fixed.
3. Thickened board to board connector
Board to board, board to wire, detachable, combination, pin row.
Usage scenarios: development boards, test boards, bulky fixed equipment (such as computer chassis wiring)
Advantages: Cheap, common, used with pin headers, very convenient for connection and measurement.
Disadvantages: Large size, difficult to fix, not suitable for mass production scenarios.
4. FPC connector plug
Many smart hardware devices require signals to be taken out of the motherboard. FPC is the best choice because it is flexible, small in size and changeable in shape.
Usage scenarios: The connection between the motherboard and the daughter board, the connection between the motherboard and peripherals, requires curved wiring, and the product space is compact.
Advantages: Small and cheap.
