What is the Importance of the Connection Between the SMP Connector and the PCB?

As an RF Coaxial Connector Factory, share with you. Because of today SMP Connector carries out the board to the board middle connection request to be increasingly big. The vertical distance between the upper and lower left and right parallel planes of the circuit board cannot ensure the same, and there is also a parallel plane shift in the alignment between the two boards, especially when multiple channels are connected together between the two boards. Because it is the transmission of radiofrequency data signals, a good overall connection appears to be critical for radio frequency characteristics.

Such characteristics include small data signal characteristics and large data signal output power characteristics. Otherwise, the characteristic impedance is not matched, which results in a large attenuation coefficient of the reflection of the surface of the data signal, a small transmission data signal, and poor output power tolerance. The SMP-MAX board-to-board connector components designed with the PCB in mind has great radial and axial tolerances and output power withstand capability, which is suitable for the use of several RF channels that need to be connected together on the board. The SMP-MAX MAX board-to-board connector component is a wave structure, which consists of a snap socket connected to the PCB by electric welding, another slide socket connected to the PCB by electric welding, and the adapter in the middle. The two bases are respectively soldered on two printed circuit boards and three patch radio frequency connectors and two printed circuit boards constitute a connector circuit board assembly.

Different scenarios are used for different PCBs. SMP RF connectors are connected to different PCBs. The RF characteristics are very different. The reason is that the transmission power circuits are not paired. It's not just adapting the printed circuit board layout. Therefore, the connector and PCB layout should be designed as a whole in accordance with the requirements of use, to ensure good RF performance with different tolerances.

Because the SMP radio frequency connector is used in the communication industry board to board interface method is different, the customer's circuit board is different. Therefore, for the place of application, a technical professional design concept is necessary.

When using the connector, the pins will be opened only after applying absolute force, but it is easier to separate them. Therefore, it is judged that the connection of the electrical connector is more important than the separation force. Therefore, the interaction of the two forces of insertion and removal can easily cause the connector to wear out. If you want to reduce the loss, you can look at these good methods: you can increase the strength of the gold-plated layer on the contact surface of the connector, which can effectively reduce friction. The contact surface of the connector can be nickel-plated and then gold-plated, which will cause less friction than gold plating directly on copper, which can reduce connector wear.
