0.25 mm Pitch Ultra-low Profile FP Back-lock onnector FF28 Upper ontact OUTLINE The FF28 connector series utilizes a cable lock mechanism to provide positive retention of the FP. This LIF connector has a dedicated upper contact to interface with the FP at a 0.25mm pitch. The ultra-low profile connector has a 0.66mm height, making it one of the smallest board mounted FP 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 FP. The FF28 connector has an ultra-low height of 0.66mm. Each individual contact is rated to 0.2A current. The FP 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. ontacts 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 FP. Since cable lock tabs electrify next contacts, please do not use the cable lock tabs as ground tabs.

Operating Instruction and autions 1.onnector mounting Instruction Lock lever is opened when delivery. onnectors are delivered with the lock lever opened. You do not have to operate the lock lever before inserting FP. (picture 1) Please do not re-flow with the lock lever in the closed condition. Please do not close the lock lever without inserting FP. Otherwise, the contact gap will become narrower and FP insertion force will rise.(picture 2) picture 1 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. 0.25N Pin 以上 0.25N Pin 以上 figure 1 figure 2 Please do not insert finger nail into the entry as it may damage the connector(figure 3) 図 3 5
