.4mm Pitch, 1.5 to 4.mm Height, Board-to-Board and Board-to-FPC Connectors DF4 Series Space saving Space saving Jun.1.218 Copyright 218 HIROSE ELECTRIC CO., LTD. All Rights Reserved. Features 1.

Multiple stack height options In addition to its space saving design, several stack heights are available and add versatility to any application. Stack heights : 1.5mm, 2.mm, 2.5mm, 3.mm, 3.5mm, and 4.

This connector utilizes a locking system that prevents accidental unmating issues and emits a clear tactile click to ensure that mating has been completed. 4.

1 .4mm Pitch, 1.5 to 4.mm Height, Board-to-Board and Board-to-FPC Connectors DF4 Series Space saving Space saving Jun Copyright 218 HIROSE ELECTRIC CO., LTD. All Rights Reserved. Features 1. High density mounting Space saving design that has a minimum connector width, yet still retains a sufficient vacuum area for easy pick-and-place mounting Minimum width : 3.38mm 2. Multiple stack height options In addition to its space saving design, several stack heights are available and add versatility to any application. Stack heights : 1.5mm, 2.mm, 2.5mm, 3.mm, 3.5mm, and 4.mm. 3. High contact reliability Despite its small stature and low profile, the contacts deliver strong contact forces and an effective mating length of.45mm on the 1.5mm stacking height. This connector utilizes a locking system that prevents accidental unmating issues and emits a clear tactile click to ensure that mating has been completed. 4. Excellent self-aligning range The use of guide ribs allows.33mm of selfalignment on this connector. 5. Reinforced structure with shock absorbing ribs Both sides of the connector have been reinforced with the addition of shock absorbing ribs. 6. Solder wicking prevention Nickel-plated barriers were added to protect the contact areas from potential solder wicking. 7. Contamination resistant design When mated, the connector s design covers the contacts which help to keep dust and other debris away from the contacts. The SMT leads are kept very close to the connector housing which also helps to prevent shorts caused by debris on the exposed contacts. 8. RoHS compliant Environment friendly and does not use RoHS specified prohibited materials. All materials and substances used to produce these parts comply with the RoHS standards. 9. High speed signal with noise prevention The shielded type can support high speed signal transmissions with noise prevention.

Washing Cleaning/washing is not recommended for this connector. Cleaning agents can deteriorate the mechanical operation and the environmental resistance of this connector. 6. Precautions Do not mate or unmate these connectors until they are mounted, failure to follow this precaution can lead to deformation or damage to these connectors. Provide another form of support to the PCB, this connector was not designed to be the main form of support. Mating and unmating with excessive force can cause damage. Do not apply excessive amounts of fl ux as it may cause excess solder and fl ux wicking. There may be a slight variance in the color of the molding between production lots, this variance will not affect the performance of the connector. Refer to the next page for the handling precautions when mating and unmating the connectors. If the connector becomes disconnected due to impact, a fall or a counterforce to the FPC, it may be necessary to hold the connector in place with an addition to the device s case or other cushioning material to hold the connector in place. 3 16

All Rights Reserved. Prior to mating, locate the guidance ribs and align the header. Do not apply excess force to the connector during mating. Doing so can lead to contact damage. Make sure that the connector is parallel to the other side, it then will drop down slightly. Continue to press it down until it is fully mated while maintaining the angle. Do not apply excessive force as it may damage the contacts. 17

18 DF4 Series.4mm Pitch, 1.5 to 4.mm Height, Board-to-Board and Board-to-FPC Connectors BPrecautions when unmating a connector Jun Copyright 218 HIROSE ELECTRIC CO., LTD. All Rights Reserved. Pitch direction Corner direction To unmate this connector, lift evenly across the header, making sure that each side stays parallel to each other. If circumstances prevent the connectors from staying parallel to each other, then one side may be lifted as shown in the diagram. This method is only approved if the connector is mounted onto an extremely rigid circuit board. If the board were to warp during this process it may result in damage to the connector or its solder joints. Do not try to disconnect these connectors by pulling on one side or a corner, or unmate it while it is securely mounted onto a rigid FPC. These actions may lead to deformities and ultimately a damaged connector. As shown in the figure to the left, do not unmate it from the width direction (front to back), it may damage contacts.

19 DF4 Series.4mm Pitch, 1.5 to 4.mm Height, Board-to-Board and Board-to-FPC Connectors BPrecautions when unmating a connector The contact may peel away if there is not enough rigidity in FPC. Receptacle FPC When mounting the receptacle side to FPC which does not have enough rigidity, the contact may peel away soldered connection. Jun Copyright 218 HIROSE ELECTRIC CO., LTD. All Rights Reserved. Header Header Receptacle FPC We recommended to mount the header side to the FPC. We have conducted evaluations on the requirements needed for FPC rigidity. If you need to mount the receptacle to the FPC, contact your local Hirose Rep for this data. Even when mounting the header side to FPC, if the rigidity of FPC is low, the connector may break as shown in the left fi gure. Please check the strength and durability of FPC before using. For the evaluation results of each item and FPC rigidity, please contact us. 19
