Understand the connector: FFC-FPC Connector

What is FFC/FPC Connector?

FFC Connectors are used to draw ribbon flat flexible cables in online board-to-board applications ( FFC） Connect to PCB Circuit.They also offer cable-to-cable configurations.These connectors have high density, very narrow form factor, suitable for tight spaces.They are commonly used in consumer applications such as laptops, cameras, computer peripherals, appliances and telephones.Single or double row connector housings are usually made of flexible plastic, polymer, engineered rubber or film, surrounding a recessed metal connector.A variety of locking styles are available.

FPC The connector will print the flexible cable ( FPC） Connect to the circuit board. FPC It's a kind FFC， The conductor is printed on the cable substrate rather than embedded therein. FPC/FFC Connectors are sometimes called ribbon connectors.

Designer selection FFC/FPC A key reason for connectors is that they have greater flexibility when used with flexible cables compared to conventional rigid circuit boards

ELCO yes FFC Early developers of type connectors, in the early 1990s with AVX merge, KYOCERA AVX Take it ELCO Responsibility for the product and continue to develop it FFC / FPC series.

although FFC It was widely used in the 1970s, but the cable initially had only direct welding or crimp contact versions.In 1986, ELCO The 8370 series was invented, this is the first one directly FFC Cost-effective clamped edge connector on top.

The unique contact actuator design has a fixing piece to prevent accidental actuator separation.The fixing piece surrounds the actuator shaft and hooks on the cavity to prevent the actuator from opening.

Design Instructions

FFC/FPC The connectors are available with pin, socket, clamping and pad contact options with single or double row housing.

Certain variants can be mixed FFC Cable and circular wire contacts provide multiple spacings such as 0.03 mm、0.5 mm、1.00 mm、1.25 mm、2.54 mm， But the most common spacing is 0.500 mm、1.00 mm and 1.25 mm。 single FFC It is possible to have different spacing between different conductors on the same cable, but this is not common.

FFC/FPC The connector is fully shielded for control EMC interference.

Various locking mechanisms can secure this connector type, including latches, staples, and fixing tabs.

Board termination options include surface mount or through holes.

0.5 mm Spacing shielding FFC/FPC The connector has one-hand automatic locking function and is resistant to high temperature (125 °C）、 High speed performance and vertical or horizontal coupling.
