Why select I-PEX Auto-Lock FFC connectors?


1 ) Auto-Lock Mechanism

Auto-lock-GIF ◆ One-step operation helps improve productivity and is also designed for robotic automation.
 ◆ Auto-lock structure reliably holds the notched FFC, creating excellent retention force against pulling and vibration.
 ◆ You can hear and feel the connector click when mating, which will prevent half-mating insertion.

2 ) High-Speed Transmission

High-transmission-GIFMulti-point ground contacts are provided for adequate impedance-matched shielded FFC. Connector design was developed for high-speed transmission by FFC creating EMI signal integrity.

Why select I-PEX FPC connectors?


1 ) Mechanical Lock Creates High Retention Force

dw5High retention force is created by the lock contacts. These contacts are on both side walls of the connector and are designed to catch and hold the designated cut out area of the FPC. The mechanical lock ensures approximately 1.7 times higher resistance compared to our 0.3 mm pitch, 19 pin count connectors without a mechanical lock. This connector is not only ideal for high vibration environments, but it is also suitable for applications that require high FPC retention. FPC retention force comparison chart is here
[ The mechanical structure shown here is a hybrid type of FPC and discrete wire connector, DW 5. This mechanical l lock structure is also adapted for MINIFLEX series.]

2 ) Hold Down to Improve Strength of Side Wall and Prevent Actuator Drop-off

MFX_Actuator(HD)Have you ever faced actuator drop-off during assembly? Certain I-PEX FPC/FFC connectors were developed with improved side wall hold down features that help the actuator from dropping off.

MFX_Actuator(Strength)When hold down is soldered, it prevents both side walls from piling-off action and distortion.

3 ) Accidental operation without the FPC inserted is no problem!

I-PEX's MINIFLEX series was developed with reliable features such as the ability to open and close the connector without the FPC inserted.

3-1 ) Connector will still function reliably

MINIFKEX F3-1MINIFLEX 3-1G

 

3-2 ) Connector still performs even though the insertion force went up

MINIFLEX F3-2
Operation without FPC insertion, basic FPC insertion force will increase.

MINIFLEX F3-2G

 

3-3 ) Retention force connector does not change

MINIFLEX F3-3
No temperature change, and no refflow soldering should be done
when actuator is in closed state. It is strongly recommended to avoid any actuator open
and close operation without FPC inserted from the beginning.
