Board-to-board connector is the connector product with the strongest transmission capacity among all connector product types at present.Board-to-board connector is mainly used in power system, communication network, financial manufacturing, elevator, industrial automation, medical equipment, office equipment, home appliance, military manufacturing, etc..
The article contains following:
1,Board-to-board connector is easy to install and disassemble
2,Slim design of the board-to-board connector
3,Board-to-board connector protect tin effect from climbing the tin
4,The structure of the board-to-board connector allows simple machine circuit design
1,Board-to-board connector is easy to install and disassemble
The biggest feature of the board-to-board connector is flexible, flexible connection, easy to install and easy to disassemble. The board-to-board connector is used in mobile phones has strong corrosion resistance and environmental resistance, without welding, can minimize the thickness of the mobile phone achieves flexible connection.
The contact structure has super environmental resistance. It is not only flexible, but also adopts a "solid connection" with high contact reliability. In order to improve the combined force of the socket and the plug, a simple lock is used in the fixed metal part and the contact part. The mechanism, while improves the combination force, makes the locking feel more pluggable
2,Slim design of the board-to-board connector
The ultra-low height of the board-to-board connector in order to achieve the purpose of reducing the thickness of the fuselage, such as the use of thinner, narrow-pitch board-to-board connectors in mobile phones for the board-to-board connector of mobile phones is the current trend , It has the advantages of high precision, high performance and small size. The process requirements for electroplating and patching are very high in manufacturing.
3,Board-to-board connector protect tin effect from climbing the tin
The ultra-narrow board-to-board connector puts forward new requirements on the electroplating process. How to ensure that the product's gold plating thickness and tinning effect does not creep in, which has become the most critical issue in connector miniaturization. The "tin creep effect" is also called SMT wick Effect, the flux has a characteristic, it will run to the place where the temperature is high, and the solder will run to the place where the temperature is high, also known as the core pull phenomenon, which is one of the common welding defects, which is more common in the gas phase reflow Soldering is a serious virtual soldering phenomenon formed by the solder leaving the pad and moving up the pin to between the pin and the chip body
4,The structure of the board-to-board connector allows simple machine circuit design
The board-to-board connector can be constructed for simple machine circuit design. By providing an insulating wall on the bottom surface of the connector, the PCB board trace and the metal terminal can be routed and wired on the bottom surface of the connector without contact, which is quite beneficial for the miniaturization of the PCB board. The performance indicators of board-to-board connectors include electrical performance, mechanical performance, environmental testing and other assembly process guidance. With the development of the times, there are more and more applications of micro-connectors, so when assembling, it must be aligned with the introduction angle. Then press it down hard to avoid product damage caused by misplaced pressing.
The test modules that need to be used in the board-to-board connector test must be able to maintain good performance in the field of small pitches, and must be able to cope with the different contact methods of the board-to-board connector male and female sockets to stabilize the connection.
