Warpage of the PCB A maximum of 0.02mm at the center part of the connector based on both ends of the connector. 5. Cleaning Not recommended. If you clean this product, please evaluate the performance before using it. (Cleaning may cause a change in the mating/unmating property and its resistance to environment) 6. Notes ■Care should be taken that mating/unmating operation when the product is not mounted on the PCB could cause damage or deformation, etc. of the contact. ■Avoid supporting the PCB only by connectors, and support it by other means than connectors. ■Care should be taken that excessive prying mating/unmating could cause damage. ■D uring hand soldering, do not apply fl ux which will cause fl ux oozing on connector. ■ This product may differ in hue due to production lot variability, but it doesn’t have any infl uence on the performance. ■Please refer to the next page for the precautions for mating/unmating. ■C onsidering the possibility of disengagement due to the counterforce caused by the drop, impact and routing of FPC, fi x the mated state by the use of housings and cushion materials, etc. ■ Caution! Do not use the connector in non-recommended conditions (i.e., rated current, rated voltage, PCB design and operating environment, etc.). Such usage could lead to material outgassing, ignition, or short-circuit, etc. Refer to the specifi cations and the guidelines for board pattern dimensions, board cautions, and connector treatment. Pleasae contact Hirose if using the connector under conditions other than those described in the specifi cations and the guidelines is being considered. 5 Jun.1.2021 Copyright 2021 HIROSE ELECTRIC CO., LTD.

BM29 Series●Ultra-small, power/signal contact design for Board-to-Board/FPC-to-Board providing 3A max current ●Notes when mating connector Be sure to mate this product manually. 　Mating procedure 1）Align the connector at the guide. 　A guide rib (tapered metal) is provided on the outer wall of the connector for mating support. 　Align the connector to this guide rib. 2）The connector enters automatically. 　The connector slightly lowers when aligned correctly. 　Find the guide by moving the connector in the X and Y directions. Finding Finding The connector slightly lowers when aligned. 3）Once aligned, mate the connector fully. 　The connector becomes parallel when aligned. You cannot move it laterally and longitudinally. 4）Confirm the mated connector. 　If incorrectly mated, remove, and mate it again. 6 Jun.1.2021 Copyright 2021 HIROSE ELECTRIC CO., LTD.

BM29 Series●Ultra-small, power/signal contact design for Board-to-Board/FPC-to-Board providing 3A max current ●Notes when unmating connector 1）Vertical direction 　 When removing the connector, remove it vertically. Number of contacts, FPC thickness, or other factors may make the vertical removal difficult. OK OK 2）Longitudinal removal 　Remove the connector in the pitch direction in a slanted manner. OK 3）Lateral removal 　Pull out the tip end of the FPC in the vertical direction. 　Applying a large force horizontally could deform the contacts. OK NG 4）Evaluate the mated state for thin FPCs. 　C onnector breakage or peeling off at soldering area could occur if the FPC does not have enough rigidity, please check the action in advance on the same type of FPC.
