FFC, FPC (Flat Flexible) Connectors

Flat Flexible Connectors (FFC, FPC) are a versatile interconnect solution for current day PCB designs and PCBA\'s, offering a variety of advantages over traditional wire-to-board connectors. FFC, FPC connectors have become popular due to their low profile, high pin density, and numerous standarized and custom options for single- and multi-row assemblies. Here we will explore the 52746-1290 application field, features, and working principle, and why they make a viable option for many PCB designs and PCBA\'s today.

Application Field

The 52746-1290 FFC, FPC connector is a two-row, 0.6mm pitch, surface mount connector set, intended for high-density applications. Due to its 0.6mm pitch, it allows for very small high-density connectors with compact circuit layouts, making it an excellent choice for both dual-sided PCBs and multi-layer PCBs. Its small form factor makes it ideal for applications such as phones, tablets, digital cameras, and other small electronic devices, as it allows for very compact circuit designs.

Features

The 52746-1290 FFC, FPC connector features a dual row design, allowing for reliable connections with up to eight contacts per row. The housing is made from die cast zinc alloy, providing strong structural integrity and reliable connections for board-to-board connections. The FFC terminals themselves are made of tin-plated phosphor bronze, for superior corrosion resistance and good electrical performance in a variety of applications. The set includes a wire retention mechanism, made of an integrated 1.2mm inner pin and a pair of metal claws that hold the wire securely in place.

Working Principle

The FFC, FPC connector works by providing electrical continuity between two circuits on two separate printed circuit boards. The connector houses the terminals, which are held securely in place by an integrated locking system. When two circuit boards are brought together, the terminals are inserted into the corresponding holes in each board and aligned and connected with the help of the contacts. Once the two boards are connected, the outer part of the housing then locks into place, securing the connection and maintaining electrical continuity.

Conclusion

The 52746-1290 FFC, FPC connector is a versatile, powerful, and reliable interconnect solution for current-day PCB designs and PCBA\'s offering a range of advantages over traditional wire-to-board connectors. With its dual row design, robust construction, and board-to-board compatibility, the 52746-1290 is an excellent choice for high-density applications such as phones, tablets, and digital cameras. The FFC, FPC connector\'s easy installation, reliability, and ability to reduce space requirements makes it an ideal solution for many electronic device designs today.
