BM28B0.6-20DP/2-0.35V(51) 板对板连接器产品概述

一、产品定位与核心价值

BM28B0.6-20DP/2-0.35V(51)是HRS广濑电机针对小型化电子设备推出的高密度立贴式板对板连接器,核心解决“紧凑空间内的多信号稳定传输”问题。其定位聚焦于对尺寸、可靠性要求严苛的场景(如可穿戴、工业控制),以“超小间距+立贴设计+镀金触头”为核心优势,平衡了密度与稳定性。

二、核心规格参数总览

该型号的参数直接支撑应用场景:

  • 结构参数:2排×20位(共20个触头),触头间距0.35mm(超小间距),立贴(SMD)安装;
  • 触头特性:纯金镀层(抗腐蚀、低接触电阻);
  • 环境参数:工作温度-40℃~+85℃,满足工业/户外场景;
  • 封装与包装:SMD封装适配自动化贴装,后缀“(51)”为HRS标准包装(1000pcs/盘)。

三、物理结构与尺寸优势

3.1 立贴设计节省空间

引脚垂直于PCB表面的立贴方式,相比卧式贴装可节省30%以上的水平空间,尤其适合便携式设备(如智能手表、无线耳机)的内部堆叠连接,避免占用主板横向面积。

3.2 0.35mm超小间距实现高密度

0.35mm的触头间距是关键:1cm宽度内可容纳约28个触头,大幅提升单位面积的信号传输能力,解决小型设备“多信号、小体积”的设计矛盾。

3.3 浮动触头吸收装配误差

HRS采用隐性浮动触头结构,可吸收PCB±0.1mm的装配偏差,避免因贴装偏移导致的触头变形或接触不良,提升量产良率。

四、电气性能解析

4.1 低接触电阻保障信号稳定

镀金触头(镀层厚度≥0.5μm)将接触电阻控制在典型值20mΩ以下,减少信号传输损耗,适配100Mbps以内的高速数字信号(如SPI、I2C)及低功耗电源传输。

4.2 额定参数满足实际需求

  • 单触头额定电流:0.3A(AC/DC);
  • 额定电压:50V(AC/DC);
  • 绝缘电阻:常态下≥100MΩ(100V DC测试);
  • 插拔寿命:≥500次(符合HRS连接器通用标准)。

五、环境适应性与可靠性

5.1 宽温覆盖多场景

-40℃~+85℃的工作温度范围,可适配:

  • 户外可穿戴设备(应对低温环境);
  • 工业传感器节点(应对车间高温);
  • 车载辅助设备(避开发动机等极端高温区域)。

5.2 抗腐蚀与抗振动能力

镀金镀层具备抗盐雾(≥48小时)、抗硫化能力,避免潮湿/多尘环境下的触头氧化;立贴引脚焊接强度≥10N/引脚,可承受10G以上振动(10-2000Hz),适配运输、工业现场等场景。

六、典型应用场景

该连接器的特性使其广泛适配以下领域:

  1. 可穿戴电子:智能手表主板与电池/心率传感器模块连接;
  2. 工业控制:小型PLC、物联网传感器节点的内部板对板连接;
  3. 医疗电子:便携式血糖仪、血氧仪的核心板与显示模块连接;
  4. 消费电子:智能家居摄像头、智能门锁的内部信号传输;
  5. 车载辅助:车载USB模块、后排显示屏的内部连接。

七、安装与选型注意事项

7.1 贴装工艺要求

  • 回流焊温度:峰值260℃(10秒内),避免超过265℃导致引脚变形;
  • 贴装精度:需自动化贴片机(精度≥±0.05mm),手动贴装易偏移;
  • 清洁:用异丙醇等中性清洁剂清洁焊接后残留,避免腐蚀镀金层。

7.2 选型配套

  • 配对连接器:需用HRS同系列型号(如BM28B0.6-20DS/2-0.35V(51)),确保触头匹配;
  • 衍生型号:若需≥1000次插拔寿命,可选择镀金厚度更高的衍生款;
  • 包装:“(51)”为批量包装,小批量可选择散料或定制包装。

该连接器凭借HRS的工艺优势,在“小尺寸、高可靠”的连接需求中具备较强竞争力,是小型电子设备内部连接的优选方案。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
