WAFER-GH1.25-3PLB 线对板针座产品概述

讯普(XUNPU)推出的WAFER-GH1.25-3PLB是一款针对小型化电子设备设计的线对板立贴针座,属于GH系列1.25mm间距产品线,核心用于信号传输与小功率电源连接,兼具高密度布局、可靠焊接与宽温适应性等特点,适配自动化生产工艺,是小型电子终端的优选连接方案。

一、产品基本信息与定位

WAFER-GH1.25-3PLB采用单排3PIN立贴(SMD)结构,是GH系列1.25mm间距连接器的典型型号,专为空间受限的电子设备设计。其定位是为智能穿戴、小型传感器模块等终端提供稳定的线对板连接,解决传统插件连接器占用空间大、焊接效率低的问题,同时满足批量生产的自动化需求。

二、核心技术参数详解

2.1 电气参数

  • 额定电流:1A(AC/DC通用,满足5V/1A以内的小功率供电与信号传输);
  • 额定电压:125V(符合低压电子设备安全标准);
  • 工作温度:-25℃~+85℃(覆盖常规室内、车载及部分工业环境的温度范围)。

2.2 机械参数

  • 插针结构:1x3P(单排3针,紧凑布局);
  • 间距:1.25mm(GH系列标准间距,比2.0mm间距节省约37%PCB空间);
  • 安装方式:立贴(SMD)(无需PCB钻孔,直接贴合表面焊接);
  • 尺寸:Z轴高度4.2mm(板上垂直高度适配薄型设备),X轴底边7mm,Y轴底边4.95mm(整体小巧,适合高密度布局)。

2.3 材料与工艺

  • 触头:黄铜基底+锡镀层(黄铜导电稳定,锡镀层提升焊接性与抗氧化性);
  • 壳体:LCP(液晶聚合物,耐回流焊高温、耐化学腐蚀);
  • 附加特征:辅助焊脚(增强焊接可靠性,防止移位);
  • 颜色:米色(常规连接器配色,便于生产检测)。

三、结构设计与材料特性

3.1 结构亮点

  • 立贴紧凑设计:SMD立贴无需PCB钻孔,减少层数与空间占用,适配智能手环等薄型设备(厚度通常≤10mm,4.2mm高度完全兼容);
  • 辅助焊脚:额外焊脚在回流焊中固定针座,避免移位导致虚焊,同时提升机械连接强度;
  • 单排3PIN布局:满足多数小型模块需求(1电源+2信号通道),无需扩展排数,进一步压缩空间。

3.2 材料优势

  • LCP壳体:耐温≥300℃,适配回流焊峰值温度(约260℃),长期使用无变形;耐化学腐蚀,适合复杂环境;
  • 黄铜+锡镀层触头:黄铜导电率28%IACS满足小电流需求,锡镀层(5-10μm)确保焊接牢固,无氧化接触不良;
  • 米色壳体:与PCB绿色阻焊层形成对比,便于生产中视觉检测。

四、应用场景与核心优势

4.1 典型应用

  • 智能穿戴:智能手环、蓝牙耳机的传感器与主板连接;
  • 小型传感器:工业温度传感器、智能家居传感器的信号输出;
  • 汽车电子:车载胎压监测接收器的内部连接;
  • 医疗设备:小型监护仪的血氧探头接口。

4.2 核心优势

  1. 高密度布局:1.25mm间距节省37%空间,适配小型化设备;
  2. 可靠焊接:辅助焊脚+锡镀层降低虚焊率,提升稳定性;
  3. 宽温适应:-25℃~+85℃覆盖多数电子设备环境,无需额外防护;
  4. 自动化适配:SMD立贴适合回流焊自动化生产,提升效率;
  5. 成本可控:黄铜+锡镀层、LCP材料组合,性价比高,适合批量采购。

五、安装与可靠性说明

5.1 安装注意

  • 采用回流焊工艺,焊盘尺寸需匹配引脚(长度为引脚1.2-1.5倍);
  • 焊接前清洁PCB表面,避免杂质影响质量;
  • 辅助焊脚需与对应焊盘对齐,防止移位。

5.2 可靠性验证

  • 焊接可靠性:1000次回流焊循环测试,无引脚脱落、壳体变形;
  • 电气可靠性:1A电流连续工作1000小时,接触电阻变化≤5mΩ;
  • 环境可靠性:-25℃~+85℃循环500次无性能下降,40℃/95%RH湿热测试1000小时无氧化腐蚀。

WAFER-GH1.25-3PLB凭借紧凑结构、可靠性能与合理成本,成为小型化电子设备线对板连接的优选方案,适配主流电子领域应用需求。

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
