DF52-4S-0.8H(21) 线对板针座产品概述

一、产品核心定位与品牌背景

DF52-4S-0.8H(21)是日本HRS(广濑电机)推出的高密度微型线对板卧贴针座,属于HRS DF系列连接器产品线,专为小型化、高密度电子设备的内部信号/电源连接设计。HRS作为全球连接器领域的技术领先品牌,以精密工艺、高可靠性著称,该产品延续了品牌在微型连接器领域的技术积累,满足消费电子、工业、车载等多场景的紧凑布局需求。

二、关键参数与结构设计

1. 基础规格参数

  • 插针结构:1排×4Pin(单排4针)
  • 间距:0.8mm(高密度规格,比常规1.0mm间距节省约20%空间)
  • 安装方式:卧贴式(SMD,表面贴装)
  • 总PIN数:4Pin
  • 工作温度范围:-40℃至+85℃(宽温适应,覆盖工业/车载环境)
  • 封装类型:SMD封装,引脚间距0.8mm

2. 结构设计优势

  • 卧贴布局:针座贴装于PCB表面,无需通孔,节省PCB背面空间,适配双层/多层板高密度布局;
  • 单排紧凑设计:1x4Pin结构减少横向占用面积,适合小型化设备的窄边安装(如智能手表内部模块);
  • 精密插针:HRS采用高精度冲压工艺,确保插针间距一致性(误差≤±0.05mm),降低接触不良风险。

三、工艺与可靠性表现

1. 接触可靠性

针座插针采用镀金表面处理(厚度≥0.3μm),减少氧化、降低接触电阻(≤20mΩ),保证信号传输稳定性;接触力设计为0.5~1.0N/针,适配HRS DF系列线端连接器(如DF52-4P-0.8C),插拔时接触紧密,避免振动导致松动。

2. 环境适应性

  • 宽温范围:-40℃至+85℃,可应对低温环境(如北方户外设备)和高温环境(如车载中控台、工业控制柜);
  • 壳体材料:采用耐高温工程塑料(PBT+GF),抗冲击(冲击强度≥80J/m)、抗老化,长期使用不变形。

3. 制造工艺适配

SMD封装兼容标准回流焊工艺(峰值温度≤260℃,时间≤10秒),适合自动化贴装生产线,生产效率提升30%以上;引脚设计符合IPC-A-610标准,焊接后焊点可靠性强,虚焊率≤0.1%。

四、安装与适配说明

1. 安装方式

采用表面贴装(卧贴),需将针座贴装于PCB指定焊盘位置,通过回流焊完成焊接;安装时需注意PCB焊盘布局与针座引脚精准匹配(间距0.8mm±0.05mm),避免错位。

2. 适配线端

需搭配HRS DF系列线端连接器使用(如DF52-4P-0.8C、DF52-4P-0.8C(51)),确保线端与针座的插针/插孔精准对接;不建议搭配非HRS原厂线端,避免接触不良或机械干涉(插拔寿命缩短50%以上)。

3. 安装注意事项

  • 回流焊前需清洁PCB焊盘(去除氧化层),保证焊接质量;
  • 插拔线端时需垂直用力(避免倾斜),防止插针弯曲;
  • 存储环境:温度25℃±5℃、湿度40%~60%,避免长期暴露于潮湿环境。

五、典型应用领域

DF52-4S-0.8H(21)因紧凑尺寸、高可靠性,广泛应用于以下场景:

  1. 消费电子:智能手机、智能手表、无线耳机的内部模块连接(如电池、传感器与主板);
  2. 工业控制:小型PLC、传感器节点、微型电机驱动器的信号接口;
  3. 车载电子:车载显示屏、导航系统、行车记录仪的内部紧凑连接(适应车载宽温环境);
  4. 医疗设备:便携式诊断仪器(如血糖仪、血压计)的内部模块连接(对尺寸和可靠性要求高)。

总结

DF52-4S-0.8H(21)是HRS针对高密度小型化设备设计的高可靠卧贴针座,参数适配多场景需求,工艺成熟稳定,是电子设备内部连接的优质选择,尤其适合对尺寸、可靠性要求严格的终端产品。

Sourcing availability signal

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
