WAFER-MX1.25-4PLB 线对板针座产品概述

WAFER-MX1.25-4PLB是讯普(XUNPU)推出的一款1.25mm间距线对板针座,兼容PicoBlade(MX 1.25)系列规格,采用单排4针立贴SMD设计,专为小型化电子设备的信号与小功率电力传输场景打造,兼顾紧凑空间与可靠连接。

一、产品核心定位与优势

该产品的核心定位是小型化电子设备的高可靠线板连接方案,针对可穿戴、智能家居等对PCB空间敏感的场景优化设计,具备以下关键优势:

  1. 窄间距紧凑设计:1.25mm引脚间距大幅节省PCB布局空间,单排4针结构适配多信号/电力传输需求;
  2. 立贴安装适配:垂直贴装方式减少水平方向占用,适合设备内部垂直连接场景;
  3. 辅助焊脚增强可靠性:额外设置辅助焊脚,分散焊接应力,避免振动、热胀冷缩导致的引脚脱落;
  4. 耐环境材料组合:黄铜触头+锡镀层保障导电稳定,LCP塑料适配回流焊高温与宽温环境。

二、关键参数与规格详情

(一)电气性能参数

  • 额定电流:1A(满足一般信号传输与小功率电力需求,如可穿戴设备的电池供电);
  • 额定电压:125V(符合低压电子设备的安全电压要求);
  • 工作温度范围:-25℃~+85℃(覆盖室内外常见环境温度,如冬季低温与夏季高温场景)。

(二)机械结构与尺寸

  • 插针结构:1x4P(单排4针),总PIN数4;
  • 封装类型:立贴SMD(表面贴装),引脚间距1.25mm;
  • 安装尺寸:
    • Z轴(板上高度):4.7mm(垂直方向占用少,适合薄型设备);
    • X轴(底边长度):10mm(4针×1.25mm间距+两端余量,适配PCB焊盘布局);
    • Y轴(底边宽度):4.3mm(横向紧凑,不占用额外PCB空间)。

(三)材料组成

  • 触头部分:黄铜材质(良好导电性与机械强度,耐插拔)+ 锡镀层(抗氧化、易焊接,降低接触电阻);
  • 塑料主体:LCP(液晶聚合物,耐高温回流焊、尺寸稳定性优异,米色外观便于识别)。

三、安装方式与应用场景

(一)安装注意事项

该产品采用立贴SMD安装,需注意:

  1. 焊盘匹配:PCB焊盘需与针座引脚尺寸、间距一致(1.25mm间距);
  2. 回流焊工艺:因塑料主体为LCP,可承受常规回流焊温度(峰值约260℃),焊接时需遵循行业标准回流曲线;
  3. 辅助焊脚利用:焊接时需确保辅助焊脚与PCB焊盘充分焊接,提升整体连接强度。

(二)典型应用场景

  1. 可穿戴设备:智能手环、手表的内部模块连接(如主板与传感器、电池的线板连接);
  2. 智能家居设备:小型传感器(温湿度、人体感应)与控制器的连接,或智能插座内部模块连接;
  3. 便携电子:蓝牙耳机、移动电源的内部信号/电力传输(如电池与主板的连接);
  4. 小型工业控制:微型传感器节点(如物联网终端)的信号输出连接。

四、可靠性设计亮点

  1. 接触可靠性:黄铜触头+锡镀层的组合,接触电阻低且稳定,减少信号衰减与电力损耗;
  2. 环境适应性:LCP塑料耐温性能优异,可在-25℃~+85℃范围内长期稳定工作,同时耐轻微潮湿与化学腐蚀;
  3. 焊接可靠性:辅助焊脚增加了与PCB的焊接点数量,分散了引脚所受的机械应力与热应力,降低了长期使用中脱落的风险;
  4. 尺寸稳定性:LCP材料的低吸水性与高尺寸精度,确保针座在焊接过程中不变形,引脚位置准确,提升插拔适配性。

总结而言,WAFER-MX1.25-4PLB凭借紧凑尺寸、可靠连接、耐环境特性,成为PicoBlade MX1.25系列的实用替代方案,满足多种小型电子设备的线对板连接需求,尤其适合对空间敏感的消费电子与物联网终端场景。

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
