0.4 mm Pitch Ultra-low Profile FPC Connector

- The FF18N’s dual contact design allows for design versatility by having both upper and lower contacts.- DDK’s original cam-type back-lock system provides reliable operation and ensures retention from inadvertent upward pulling of the FPC.- The FF18N ZIF connector utilizes a cable lock mechanism to provide positive retention of the FPC.- Back-lock mechanism ensures retention from inadvertent from upward pulling of the FPC.- These ZIF connectors are delivered with the lock lever opened for maximum production efficiency.- Available in pin counts for this low profile connector are 4, 5 and 6 pins.- Contacts utilize a nickel barrier to prevent solder wicking- High-temperature resin for lead free reflow process- FF18N ZIF connectors are delivered in a tape and reel package for automated machine processes.

MATERIAL/FINISH

【Upper and lower Type】

FF18N series is a connector with a cable lock mechanism to provide positive retention of the FPC. This LIF connector has a both upper and lower contacts to interface with the FPC at a 0.4mm pitch. The ultra-low profile connector has a 0.66mm height, making it one of the smallest board mounted FPC ZIF connectors on the market.

1．Connector mounting Instruction

Please do not load (0.5N×pin Min.) from the top of the lock lever. (fi gure ① ) And please do not load (0.5N×pin Min) toward the opposite direction of the lock lever, (fi gure ② )otherwise the lock lever may be broken or contacts may be deformed.

Connectors are delivered with a lock lever opened.You do not have to operate the lock lever before inserting FPC.(picture ① )

Please do not re-fl ow with the lock lever closed condtion.Please close the lock-lever with inserting FPC, otherwisethe contact gap become narrower and FPC insertion force will rise. (picture ② )

Lock lever is opened, delivered.

2．FPC InsertionPlease insert FPC to the pattern side up.(picture ③ ) when using upper contacts.Please insert FPC to the stiff ener side up(picture ④ ) when using lower contacts.Please insert FPC straight to the connector. Due to the semi-reteining mechanism, some insertion force is necessary when inserting FPC.Please make sure whether FPC is inserted fully.

3．Correct FPC Insertion PositionAs illustrated (picture ⑤ ), you can check short insertion(picture ⑥ ) and diagonal insertion(picture ⑦ ) by checking the position of connector housing and FPC positioning edge.If the FPC positioning edge is exposed from the connector housing, it may be short insertion or diagonal insertion. Please re-insert FPC fully.
