FFC, FPC (Flat Flexible) Connectors

Flat Flexible Connectors (FFCs) and Flat Panel Connectors (FPCs) are some of the most widely used type of electrical connectors. They are used in a wide variety of applications, ranging from motor control and industrial automation to consumer electronics.

FFC/FPC connectors generally consist of two flat strips of conductor material that can bend to form a variety of shapes. Generally, the strips are either zero-ohm resistors or long parallel traces of copper. In some cases, the traces may be plated with a noble metal such as gold or silver. The contacts are generally formed by pressing the strip into contact with another conductor.

FFC/FPC connectors are typically used for applications such as board to board, cable to board or panel to panel connections. They offer advantages such as low height profile, low insertion force, robustness, reliability and cost savings. FFCs/FPCs are widely used in a variety of products, including computers, phones, and other consumer electronics, as well as in medical and automotive applications.

The working principle of FFC/FPC connectors is quite simple. Two flat strips of conductor material are bent to form contacts, which are then pressed together by a mechanism such as a spring or finger. The contacts remain in contact until the spring is released or the finger is removed. The amount of force required to hold the contacts together depends on the material used and the size and shape of the contact.

FFC/FPC connectors have many advantages over traditional wired connections. They allow for low-profile connections with minimal height, offer easy installation and removal, are highly reliable and cost-effective, and provide a secure connection. FFC/FPC connectors are also extremely durable and can withstand harsh environmental conditions such as extreme temperatures and vibration.

In conclusion, FFC/FPC connectors are a versatile and reliable type of electrical connector that offer a number of advantages over other types of connectors. They are widely used in a variety of applications, including motor control and industrial automation, consumer electronics and automotive applications. The working principle of FFC/FPC connectors is quite simple and they offer advantages such as low height profile, low insertion force, robustness, reliability, cost savings and durability.
