The electronic components and electromechanical components have electrical contacts on the PCB, and the electrical connection between two discrete contacts is called interconnection. So what are the ways of PCB interconnection?
Welding method
This method has the advantages of simplicity, low cost and high reliability, and can avoid the failure caused by poor contact. The disadvantage is that it is inconvenient to exchange and maintain.
1. PCB wire welding
This method does not need any connectors, this method does not need any connectors, just use wires directly weld the external connection point on the PCB with the components outside the board.
2. PCB layout welding
The two PCB boards are connected by Flat cable connection, which is both reliable and not prone to connection errors.
3. Direct welding between PCBs
This method is often used for the connection between two printed boards with an included angle of 90 degrees.
Plug and connector connection mode
In relatively complex instruments and equipment, plug connection is often used. It not only ensures the quality of mass production of products, reduces the cost of the system, but also provides convenience for debugging and maintenance.
1. Printed board socket
This connection method is often used in complex instruments and equipment. This method is to make a printed plug from the edge of the PCB, and the plug part is designed according to the size of the socket, the number of connections, the contact distance, the position of the positioning hole, etc., so that it matches the special socket.
2. Standard pin connection
This method is used for external connection of PCB board. When connecting two PCBs through standard pins, they are generally in parallel or vertical state, which is easy to realize mass production.
