High density mounting capability A space saving design that keeps the connector compact, but still maintains an adequate vacuum area (no less than 0.7mm wide). Depth DS : 2.3mm DP : 1.78mm 2.46mm 2.98 ∞ 10.4 =About 31.0mm2 BM20 2.3 ∞ 10.48 = About 24.1mm2 1.78 mm Dec.1.2022 Copyright 2022 HIROSE ELECTRIC CO., LTD. All Rights Reserved. Existing products 9.32mm 9.4mm Board occupied area Existing products 2. Reliable contact performance A 27.1% reduction in size! 2.46 ∞ 9.32 = About 22.9mm2 Even though the mated height is low, the BM20 still leads it class in maximum effective mating lengths for each mating height. Height 0.8mm : 0.2mm Height 0.6mm : 0.15mm The addition of the two point contact system adds more reliability to the contacts. BM20 1.78 ∞ 9.4 = About 16.7mm2 Vaccum pick-up %#, %#, 3. No restrictions to PCB pattern design for the 0.8 mm height connector *1 This series utilizes a thin wall to insulate the bottom surface of the connector and maintains an effective mating length of 0.2mm. This removes any restriction for PCB pattern layout design under the connector. Note *1: There are some restrictions for the 0.6 mm height style. 4. Enhanced mating operations The structure uses guide ribs to ease the mating process and offers a self alignment range of up to 0.3mm. A clear tactile click is used as an indicator to the user that the mating process was completed. Mating diagram (cross section) H=0.8 2-point contact structure Molded Bottom surface structure 5. Drop and shock resistant structure Dimples were designed into the contacts to increase their retention force and to absorb the shock delivered from a drop or other impact. 6. Debris resisting design H=0.6 Molded Bottom surface structure When mated, the connector’s design covers the contacts which help to keep dust and other debris away from the contacts. The SMT leads are kept very close to the connector housing which also helps to prevent shorts caused by debris on the exposed contacts In cases where the application will demand a high level of reliability, such as automotive, please contact a company representative for further information. 2021.12③ 1 BM20 Series●0.4mm Pitch, 0.6 and 0.8mm Height, Board-to-Board and Board-to-FPC Connectors ■Product Specifications Rated Current 0.3A Ratings Rated Voltage AC, DC 30V Dec.1.2022 Copyright 2022 HIROSE ELECTRIC CO., LTD.

Cleaning agents can deteriorate the mechanical operation and the environmental resistance of this connector. 6. Precautions 8 ■Do not mate or unmate these connectors until they are mounted, failure to follow this precaution can lead to deformation or damage to these connectors. ■Provide another form of support to the PCB, this connector was not designed to be the main form of support. ■Using excessive force to mate or unmate this connector can damage the contacts. ■Do not apply excessive amounts of flux as it may cause the solder and flux to wick. ■There may be a slight variance in the color of the molding between production lots, this variance will not affect the performance of the connector. ■Refer to the next page for the handling precautions when mating and unmating the connectors. ■If the connector becomes disconnected due to impact, a fall or a counterforce to the FPC, it may be necessary to hold the connector in place with an addition to the device’s case or other cushioning material to hold the connector in place. BM20 Series●0.4mm Pitch, 0.6 and 0.8mm Height, Board-to-Board and Board-to-FPC Connectors ●Handling precautions when mating 7B'%"9E"%#)K Dec.1.2022 Copyright 2022 HIROSE ELECTRIC CO., LTD.

All Rights Reserved. BM20*(#)-*DS-0.4V To unmate this connector, lift evenly across the header. Make sure that each side of the connector stays parallel to the other. If circumstances prevent the connectors from staying parallel to each other, then one side may be lifted as shown in the diagram. This method is only approved if the connector is mounted onto an extremely rigid circuit board. If the board were to warp during this process it may result in damage to the connector or its solder joints. Pitch direction Do not try to disconnect these connectors by pulling on one side or a single corner, or to unmate it when it is hasn’t been securely mounted onto a rigid FPC. These actions may lead to deformities and ultimately a damaged connector. Prior to the mounting of these connectors we recommend that you check the rigidity of your FPC to ensure that it meets the standards needed to support these connectors. Corner direction If the FPC is not strong enough by itself, a stiffening backing may be applied. If the FPC has a low rigidity the connector may break (as shown in the illustration to the left). We recommend a backing of no less than 0.3mm of glass epoxy and 0.2mm of stainless material. 10 BM20 Series●0.4mm Pitch, 0.6 and 0.8mm Height, Board-to-Board and Board-to-FPC Connectors Dec.1.2022 Copyright 2022 HIROSE ELECTRIC CO., LTD.
