An important component that is essential for most electronic devices is a connector. The QFS-026-04.25-H-D-PC4 is an example of a rectangular connector from the array, edge type, mezzanine board to board category. This is just one of a vast array of connectors produced for the electronics marketplace.

Application Field and Working Principle

The QFS-026-04.25-H-D-PC4 case size is 26mm by 10mm, with the overall length of the connector being 104.25mm. It has four rows of 24 contacts, allowing for a possible 96 contacts in total. The pin size is 0.635mm with a pitch of 1.27mm. It is mainly used to provide a connecting bridge between two printed circuit boards (PCBs). It is also often used to connect electronic devices and other components together.

The QFS-026-04.25-H-D-PC4 is a membrane cell type connector. This type of connector works by directing electrical contacts through a plastic membrane to the contacts of the other boards, creating a secure connection. The main advantage of using a membrane-based connection is that it is more reliable than other types of connector connections, as it is virtually impervious to corrosion, dust, and other environmental factors. It is also much easier to assemble than other types of connectors.

The QFS-026-04.25-H-D-PC4 contains a core layer that is comprised of two different types of conductive material. The first type is the upper conductive layer, which contains a copper foil and a layer of conductive adhesive. This forms the core contact for the connection of electrical energy between the two components. The second type of conductive material is the lower conductive layer, which is composed of a gold-plated copper layer.

The outer layers consist of a nonconductive (inert) material, such as polyester, which provides insulation for the inner layers. This insulation helps to protect the connection from accidental shorts and ensured that the electrical energy does not dissipate through the connection. The outside of the connector also contains a thermoplastic elastomer (TPE) which provides a buffering effect, ensuring that the stresses between the two components are minimized.

Materials and Coatings

The components of the QFS-026-04.25-H-D-PC4 are made from a variety of materials, including copper and gold. The main body of the connector is made from tin phosphor bronze, which is corrosion-resistant and has an excellent electrical conductivity. The contacts are made from gold-plated copper and the insulation layer is composed of polyester and thermoplastic elastomers.

The body of the connector has a plating finish to help protect it from corrosion and wear. Additionally, the contacts are gold-plated to help ensure the transmission of electrical energy and reduce the chances of an accidental short circuit. The insulation material helps to provide added protection and ensure that the electrical energy does not dissipate.

Conclusion

The QFS-026-04.25-H-D-PC4 is a popular rectangular connector that is used for connecting two printed circuit boards together. It is made from a variety of materials, including copper, tin phosphor bronze, and gold, and contains a core layer of two different conductive materials and an insulation layer made from polyester and thermoplastic elastomers. The plating finish and gold plating on the contacts ensure that energy is efficiently transferred and that it does not dissipate due to environmental factors. This makes it an essential component for many electronic devices and other components.
