IntroductionThe QFS-026-06.25-SL-D-A-TR is an array type mezzanine connector used to link two or more printed circuit boards (PCBs) in electronic and telecommunications applications. It is used to ensure continuity of electrical performance between two points. This type of connector is known as an edge type mezzanine for its relatively compact design, easier installation and integration with existing system architectures.Application FieldsQFS-026-06.25-SL-D-A-TR connectors are typically used in industrial, medical, automotive, telecommunications, and computer applications. In addition, they are especially suited for high-speed data/signal transfer. These connectors offer design engineers a high degree of flexibility, enabling them to easily configure circuits by selecting the right combination of contact type, contact size, body size, and signal/power capabilities. Construction and StructureQFS-026-06.25-SL-D-A-TR connectors are composed of a set of conductive terminals, each of which consists of a male contact, female contact, and a dielectric (insulating) base or panel. Signals are transferred through the contacts, which can be either solder or crimp type. The terminals are arranged in contact rows with two patterns (row A and B types) alternating one another. In addition, this type of connector includes a substrate, which is a printed circuit board (PCB) with two soldered-on layers that provide spacing, insulation, and electric discharge protection as well as a protective plate.FeaturesQFS-026-06.25-SL-D-A-TR connectors are characterized by high contact density, shock and vibration-resistant construction, secure mating and unmating features, good retention force, and extremely low ground bounce. As with other mezzanine connectors, the contacts are arranged in a rectangular array, allowing easy routing in adjacent circuit boards. This type of connector provides a rugged yet flexible interconnect solution for a wide range of residential, public, and industrial applications.Working PrincipleQFS-026-06.25-SL-D-A-TR connectors employ an array of contacts to provide a reliable electrical connection between two or more boards. The connector consists of a series of terminals, each with a male and female contact, arranged in rows in alternating columns. Power or data is transmitted between the male and female contacts, providing an electrical connection between the adjacent printed circuit boards (PCBs). The terminal and substrate layers provide spacing, insulation, and electromagnetic interference (EMI) protection. The device\'s protective plate provides additional retention force and enhances its durability.
