BM28 Series ●0.35mm pitch, 0.6mm height, Board to Board or Board to FPC Connectors with Rated Current Up to 5A ⿆Precautions 1. Recommended solder temperature profi le 2. Recommended manual soldering conditions Soldering iron temperature : 340 ± 10°C ; Soldering time : within 3 seconds 3. Recommended stencil thickness and open area ratio to PCB pattern area Thickness : 0.08mm Aperture ratio : 100% on the DS side ; 100% for signal contact, and 80% for power contact on the DP side 4. Board warpage A maximum of 0.02mm at the center of the connector relative to each end of the connector. 5. Cleaning conditions Cleaning is not recommended. If you clean this product, please evaluate its performance before using it. (Cleaning may impair the mating/unmating properties and lower resistance to environmental factors) 6. Precautions ● Care should be taken when mating/unmating the connector when it is not mounted on the PCB. This could cause damage or deformation of the contacts.

• Avoid supporting the PCB only with the connectors. Support it by other means such as bolts, screws, posts, etc.
• Care should be taken that excessive prying mating/unmating could cause damage.
• In the case of hand soldering, please do not apply any fl ux, which could cause fl ux wicking.
• This product may have slight color differences due to production lot variability, but this does not the performance.
• Please refer to the next page for precautions regarding mating/unmating.
• Because the product can disengage if dropped (or other impact), and by FPC routing, it is advised to secure the mated connectors to the board with housings and cushioning materials.
• 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. Note 1 : The temperature refers to the surface temperature of the PCB in the area of the connector lead. [Conditions] 1. Peak temperature : Maximum of 250ç 2.

Caution! If excessive force is applied, the connector could crack or shaved which could lead to a defect in contact resistance. Guiding condition Mated condition When guided, the connectors are aligned parallel to each other, with longitudinal and lateral movements restricted. Mate them parallel to each other. Handle with care when mating a connector Handle with care when un-mating connectors ɹɹɹɹɹ Un-mate connectors parallel to each other. Pitch direction If the connector cannot be un-mated parallel it can be removed diagonally from the pitch direction, as shown in the Figure. However, the connector can be broken if the FPC is not rigid. Please confirm rigidity of the FPC at the time of trial production. Corner direction Do not pull from the corner, If it is pulled from the corner as shown in the left Figure, the contact and connector could be damaged. Please provide a reinforcing plate for the FPC. If the rigidity of the FPC is not sufficient, the connector may break as shown in the left Figure. Please check the action of the FPC to be used repeatedly. A reinforcing plate of 0.3mm or thicker made of glass epoxy material is recommended, or 0.2mm or thicker stainless steel. NG NG OK OK OK Powered by TCPDF (www.tcpdf.org)
