Higher density of the board-mounted components High contact reliability - Effective connection wipe of 0.45 mm Extremely small board mounting pattern and low abovethe-board profile makes the connectors ideally suited for small device applications. Header Shock-absorbing rib 1.5~4.0mm 2. Stacking height variation : 1.5mm to 4.0mm 3. High contact reliability Despite connectors small size and low profile the contacts provide strong contact forces and long contact wipe (0.45 mm), guaranteeing reliable electrical and mechanical performance. 5.0mm Other HRS connector 0.45mm 4. Large self-alignment distance The connectors will self-align within 0.33 mm. Interlock indentations Receptacle 5. Confirmation of the fully mated condition (for 10 to 50 positions) Positive "click" sensation confirms correct insertion and connection of all contacts. 6. Built-in shock absorbing feature 7. Solder wicking prevention Nickel-plated barriers provide protection against solder wicking into the contact areas. 8. Contact area protection External walls protect the exposed contact areas from intrusion of flux or foreign particles. 9. RoHS compliant All components and materials comply with the requirements of the EU Directive 2002/95/EC. Applications Cellular phones, Digital Video Cameras, Digital Still Cameras, portable devices and other small applications requiring reliable board-to-board or FPC-to-board connections. 121 Stacking Height variation Stacking Height 10 20 24 30 40 44 50 60 70 80 100 Number of Contacts The protrusions and indents in the insulator bodies protect the connectors from failures when exposed to sudden impact. 1.5mm 2.0mm 2.5mm 3.0mm 3.5mm 4.0mm K K K K K ---K K K K K ---K ---K K ---K ---- ---K K ---------- K K ---K ---- ---------K ---K K K ---------- ---------K ------K K ---------- ------------- ---- ------------- : Reserved for product expansion The product information in this catalog is for reference only.

Note 2: The temperature profile indicates the board surface temperature at the point of contacts with the connector terminals. 2.Recommended manual soldering Manual soldering: 34010c for 3 seconds 3.Recommended screen thickness and Thickness: 0.12 mm open area ratio (Pattern area ratio) Open area ratio: 80% 4.Board warpage Maximum of 0.02 mm at the connector center, with both ends of the connector as reference points. 5.Cleaning conditions Cleaning is not recommended. When cleaning, please evaluate as if can deteriorate the performance including mechanical operation and environmental resistance. 6.Precautions * Mating and un-mating of the connectors when not soldered on the boards is not recommended as this may cause deformation of the terminals, damage to the contacts or insulators. Mated connectors should not carry weight of the board by themselves. Provide some other support of the boards. When mating/un-mating do not twist or lift by the corners. Apply the forces evenly across the entire length and width of the connectors taking care NOT to damage or deform soldered terminations. Exercise extreme caution when mating/ un-mating when the connector is mounted on a nonrigid (flexible) substrate. Do NOT pull on the flexible substrate. Slight discoloration on the insulating materials will not affect form, fit or function of the connectors. 131 The product information in this catalog is for reference only.

DF40 Series0.4 mm Contact Pitch Board-to-Board /Board-to-FPC Connectors BHandling Precautions when mating the connectors DF40*-*DP-0.4V Header DF40*-*DS-0.4V Receptacle Keep the connectors parallel to each other when positioning Do not attempt to mate the connectors staring at one end or side. Press-down evenly until slight resistance is felt. Overcoming this slight resistance will complete the mating receptacle with the header. A definite "click" sensation will confirm the fully mated condition. 132 The product information in this catalog is for reference only.

DF40 Series0.4 mm Contact Pitch Board-to-Board /Board-to-FPC Connectors BHandling Precautions when un-mating the connectors DF40*-*DS-0.4V Fully mated DF40*-*DP-0.4V Lift even one side, keeping both boards parallel to each other. When handling, circumstances prevent the connector from being kept level during the un-mating. One end may be lifted separate as shown. However, to utilize this procedure the connector must be mounted on a sufficiently rigid circuit board. Any deflection of the board during this operation may result in damage to the connectors or solder joints. Pitch Orientation Corner Orientation Do not attempt the start of the un-mating of the connectors from one side or corner. When un-mating is from the width orientation, as illustrated in the diagram to the left, connector could be damaged. Do not remove from the width orientation.

DF40 Series0.4 mm Contact Pitch Board-to-Board /Board-to-FPC Connectors BHandling Precautions when un-mating the connectors FPC Receptacle Low rigidity FPC should not be used for mounting of the receptacle. Un-mating of the connectors when the receptacle is mounted on the extremely flexible FPC can result in solder joint failure or damage to the connector itself. Header It is highly recommended that the receptacle be mounted on the rigid PCB and the header on the FPC. Header Contact HRS when specific application requires mounting of the receptacle on the FPC. All published performance data is based on connectors mounted on rigid FPC and PCB. Receptacle Failure to exercise caution when un-mating connectors mounted on the non-rigid FPC may also result in connector breakage. 134
