Introduction

QFS-078-06.25-S-D-P is a rectangular mezzanine connector designed for high-density and secure connection between two printed circuit boards (PCBs). The edge-mountable, low-profile design of the connector facilitates the connectivity in various critical applications, such as in the medical, telecom, industrial, computer peripherals, aerospace, and automotive fields. The connector offers an array of features such as multi-row pitches, solder-dip mounting, and pick-and-place mounting support.

Application Field and Working Principle

QFS-078-06.25-S-D-P connectors are used in applications requiring high-density and secure connections between two PCBs, such as those used in the medical, telecom, industrial, computer peripherals, aerospace, and automotive fields. The connector is designed to provide a secure connection without the need for soldering, thanks to its integrated solder-dip mounting support.The connector is implemented with two opposing rows of pins which mate with respective slots on one side, and with via-plated holes on the other. The pins are inserted into the opposing board in a stacked, alternating pattern. They are then soldered in place using a solder-dip process. The soldered connection is highly secure and can not be easily removed.Once connected, the two boards are firmly grounded together, reducing the potential of signal interference and providing additional security in the application. Furthermore, the low-profile design of the connector ensures that the profile of the finished product is minimized.

Conclusion

QFS-078-06.25-S-D-P mezzanine connectors offer a convenient, efficient, and secure solution for a variety of critical applications. They are designed for high-density and secure connections and provide soldered connections without the need for additional tools. The connectors are also highly convenient due to its solder-dip mounting and pick-and-place mounting support. Its low-profile design helps ensure that the final product maintains a minimal profile.
