FFC, FPC (Flat Flexible) Connectors

Flat Flexible Connectors, or FFC/FPC, are electrical connectors used in a wide range of applications. They are used to connect printed circuit boards together in various electronic devices including computers, cell phones, consumer electronics, and medical devices. FFC/FPC connectors are also used to connect offboard components such as sensors and motors to a circuit board. These connectors have a flat, flexible design that allows them to be embedded in a device for a neater look, and they can also be used in very small spaces.

FFC/FPC connectors have two main types of applications: Board-to-board applications and peripheral or offboard applications. Each type of application has different requirements and different components. When using FFC/FPC connectors in board-to-board applications, the connector is used to join two printed circuit boards together. This type of connection is usually used for internal connections within the device, such as connecting two sections of a laptop or linking the processor and RAM on a motherboard. In peripheral applications, the FFC/FPC connector is used to join offboard components to a PCB, such as mounting a touchpad or sensor to a circuit board.

In addition to their flat design, FFC/FPC connectors are also designed to be flexible, allowing them to be routed around tight corners or bends. This makes it possible to create very flexible and compact designs that can be used even in small and confined spaces. The flexibility of the connectors helps ensure that the connection is maintained even in difficult-to-reach areas. The flexibility of the FFC/FPC connectors also means that they are less likely to break or come loose compared to other types of connectors, such as ribbon connectors.

The working principle of FFC/FPC connectors is fairly simple. The connectors are composed of a number of pads, or contacts, which are connected to the terminals on a PCB via plated-through holes. The flat flexible cable is routed around the connectors and the contact pins are then inserted into the holes in the cable. Once the connection is made, the contacts will create an electrical path between the contact pin and the PCB, allowing electrical signals to travel between the two components.

FFC/FPC connectors are a highly versatile type of connector that can be used in many applications. Their small size and flexibility makes them ideal for use in small or confined spaces, and their robust design makes them durable and long-lasting. They are also relatively easy to assemble and install, making them a popular choice for many types of electronic designs.
