1 NEW.35mm Pitch.8mm Height Hybrid Power/Signal Connectors for Board-to-Board and FPC-to-Board BM24 Series Conventional type (P=.35 mm, 2 contacts) Features 1 Rated current : 5A The compact BM24 Series features a space-saving design with the power contacts rated at 5A, and the signal contact rated at.25a. (Fig.1) 2 High contact reliability A 2-point contact structure for both power and signal contacts provides high contact reliability. (Fig.3) 3 Enhanced mating process A guide rib ensures self-alignment during mating, with an alignment range of.3mm. In addition, a tactile click is generated upon mating completion, preventing incomplete mating and enhancing mating operability. 4 Supports USB3./3.1 transmission The signal contact supports USB3./3.1 signals.

Heat section : 22ç min., within 6 seconds 3. Preheat section : 15 to 18ç, 9 to 12 seconds 4. Number of reflow cycles : Maximum of 2 cycles Note 1 : The temperature refers to the surface temperature of the PCB in the area of the connector lead. Note 2 : When you use nitrogen refl ow, please mount the product with the oxygen concentration at a minimum of 1, ppm. Please contact us if the concentration is below 1, ppm. Soldering iron temperature: 34 ± 1 C ; Soldering time: within 3 seconds Thickness:.1 mm Aperture ratio : 8% on the DS side ; 7% on the DP side 4. Board warpage A maximum of.2 mm 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 flux, 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.

6 Powered by TCPDF ( BM24 Series.35mm Pitch.8mm Height Hybrid Power/Signal Connectors for Board-to-Board and FPC-to-Board Handling Precautions when Mating Connectors BM24*DS.35V BM24*DP.35V Do not apply excessive force while positioning the connector for mating. Too much force will cause damage/shaving of the housing material, and may lead to a failure in contact resistance and other issues. Handling Precautions when Un-mating Connectors BM24*DS.35V BM24*DP.35V Pitch orientation Correct Once the positioning for correct mating is obtained, mating height drops down one stage. There is no movement in the horizontal direction. Mating should occur at this stage, while taking care that there is no horizontal movement. Be sure to unmate the connectors in a straight line direction. If you are unable to unmate a cnnector in straight line direction due to a handling issue, pull it out in an oblique direction as shown in the figure on the left. However, the connector could be broken if there is not enough support on the FPC. Please account for this during prototyping. Unmating a connector by a corner, as shown in the figure to the left, could damage the connector and contacts. Never disconnect connectors using a corner. Corner orientation Incorrect Make sure that the FPC has a stiffener of sufficient strength. If the stiffener is not strong enough, the connector could be broken, as shown in the figure on the left. It is advised to test the FPCs strength by repeated mating/unmating cycles. We recommend the use of a glass epoxy material with a minimum thickness of.3 mm, or a stainless steel material with a minimum thickness of.2 mm. 6-3,Nakagawa Chuoh-2-Chome,Tsuzuki-Ku,Yokohama-Shi ,JAPAN TEL: Fax: The characteristics and the specifications contained herein are for reference purpose.
