PCB commonly used terminals
At present, the country has higher and higher requirements for environmental protection and greater efforts in link governance. This is a challenge but also an opportunity for PCB factories. If PCB factories are determined to solve the problem of environmental pollution, then FPC flexible circuit board products can be at the forefront of the market, and PCB factories can get opportunities for further development.

The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of him. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields. From this point of view, the environmental protection problems of PCB factories can be solved from the following two points.

It depends on whether it is classified according to material or style. If it is classified by material, there should be more copper terminals; according to the style, PCB terminals are divided into plug-in terminal blocks, direct welding terminal blocks, and springs. There are more plug-in terminals and spring-type terminals.

Spring-type terminal is a new type of terminal that utilizes spring-loaded devices. It has been widely used in the world's electrical and electronic engineering industries: lighting, elevator elevator control, instrumentation, power supply, chemical and automotive power, etc. The metal parts of the spring-type series terminal blocks are all designed with spring devices, and the plastic body is made of PA66 insulating material. The spring-loaded terminal blocks are easy to operate, free of maintenance, and have an airtight contact device system, which is durable, reliable, and cost-effective.

The plug-in series terminal block PTB is made up of two parts plug-in connection, one part presses the wire tightly, and then plugs into the other part, this part is soldered to the PCB board. The mechanical principle of this connection bottom and this anti-vibration design ensure the long-term airtight connection of the product and the reliability of the finished product. Mounting ears can be added at both ends of the socket. The mounting ears can protect the tabs to a large extent and prevent the tabs from being arranged poorly. At the same time, this socket design can ensure that the socket can be correctly inserted into the mother body. The socket can also have assembly buckle and lock buckle. The assembly buckle can be more firmly fixed to the PCB board, and the locking buckle can lock the mother body and the socket after the installation is completed. A variety of socket designs can be matched with different matrix insertion methods, such as horizontal, vertical or inclined to the printed circuit board, etc., and different methods can be selected according to customer requirements. Either metric wire gauge or standard wire gauge can be selected. No minimum requirements
