0.25 mm Pitch Ultra-low Profile
FPC Back-lock Connector
FF28 Series【Upper Contact】
OUTLINE
The FF28 connector series utilizes a cable lock mechanism
to provide positive retention of the FPC. This LIF connector
has a dedicated upper contact to interface with the FPC at a
0.25mm pitch. The ultra-low profile connector has a 0.66mm
height, making it one of the smallest board mounted FPC LIF
connectors on the market.
FEATURE
・DDK’s original cam-type back-lock system provides reliable operation and ensures retention
from inadvertent upward pulling of the FPC.
・The FF28 connector has an ultra-low height of 0.66mm.
・ Each individual contact is rated to 0.2A current.
・ The FPC is mechanically retained within the FF28 with DDK’s cable-lock design.
・These ZIF connectors are delivered with the lock lever opened for maximum production efficiency.
・Contacts utilize a nickel barrier to prevent solder wicking.
・The housing and lock lever are made of heat-resistant resin making possible lead-free reflow soldering.
・FF28 ZIF connectors are delivered in a tape and reel package for automated machine processes.
Note : Please do not close the lock lever without inserting the FPC.
Since cable lock tabs electrify next contacts, please do not use the cable lock tabs as ground tabs.

○ Operating Instruction and Cautions
Lock lever is opened when delivery.
1.Connector mounting Instruction
・Connectors are delivered with the lock lever opened.
You do not have to operate the lock lever before inserting FPC.
(picture ①)
・Please do not re-flow with the lock lever in the closed condition.
picture ①
・Please do not close the lock lever without inserting FPC.
Otherwise, the contact gap will become narrower and FPC insertion
force will rise.(picture ②)
・Please do not load from the top of the lock lever.(figure ①)
And please do not load toward the opposite direction of the lock lever.(figure ②)
Otherwaise, the lock lever may be broken or contacts may be deformed.

2.FPC Insertion
Please insert the FPC with the pattern side up.(correct: picture ② , wrong:picture ③)
・Please insert the FPC straight into the connector.
Due to the semi-retaining mechnism, some insertion force is
necessary when inserting FPC.
FPC insertion is completed when the edges of the FPC are
touching connector frange.

3.Correct FPC Insertion Position
・Check line enables a visual verification of the mating position.
It prevents shallow and diagonal insertion.(picture ⑤、⑥、⑦)
