0.4-mm pitch board to fpc connector xb4a/xb4b 39 safety precautions precautions for correct use for operating 1. regarding the connector stacking operation, it should be con- firmed there is no extreme displacement and tilt in the stacking contact areas between a plug and a socket before the stacking operation of the connectors. 2. ensure that the connector stackings are fully seated. ? an incomplete stacking state may cause the failure of contact reliability. 3. do not apply an extreme load when inserting or drawing out the connector. ? the connector may be damaged, resulting in faulty contacts. 4. when stacking the plug and socket, press the back side of printed circuit board mounted with them and then couple with as little twisting force as possible. ? doing so may cause the terminal and housing to change shape or the housing to crack. 5. when drawing out, hold the edge of the printed circuit board near the connector and remove as vertic ally as possible, as described in the figure below. ? drawing out the plug with too much force may have possibility to change shape of terminal solder/housing crack. 6. do not insert a foreign object such as a tweezers into the connec- tor stacking contact area. ? doing so may cause the plating peel off and deform the shape of the terminal. for mounting 1. the reflow conditions are as st ated in omron?s specifications and guidelines. these conditions, however, depend on the type of solder, the manufacturer, the amount of solder, the size of the circuit board, and the other mounting materials. 2. when mounting the connector by manual soldering, observe the following precautions to ensure contact reliability. ? conditions for manual soldering: 350 10 c 3 1 sec ? do not apply an excessive amount of solder. excessive solder will cause the flux creap. ? do not apply the soldering iron to the mounting terminal. doing so may cause the connec tors to change shape. ? do not apply the soldering iron to any parts of the connector other than the mount attachments. doing so may cause the con- nector to change shape. for designing 1. when mounting the connector to the fpc, design the fpc so that extreme peel force should not be applied directly on to the con- nector. if the fpc bends near the connector, or if the fpc is used with extreme peel force directly on to the connector, it may cause a contact loss. 2. if the connector-mounted fpc is installed at a location or in any equipment that will subject the fp c to continuous shake or move- ment, secure the fpc or take any countermeasure against fpc disconnection from the connector. 3. do not use plural connectors on same pcb. ? doing so may cause solder and housing crack. 4. when locating the connector on t he printed circuit board, be sure to allow space for the stacking operation. 5. ensure a metal mask thickness of t = 0.10 to 0.15 mm. the recommended open area of the metal mask is 90% of the printed circuit board?s mating dime nsions as shown in the dimen- sional diagrams. row direction pitch direction
