KOA RCWCTE 铁环型贴片测试点产品概述

一、产品核心定位与典型应用场景

RCWCTE是KOA针对电子设备生产测试、维护调试需求推出的铁环型贴片式PC测试点,核心功能是在PCB上设置便捷的信号采集节点,支持在线测试(ICT)、功能测试(FT)及后期故障排查。

典型应用领域

  1. 消费电子:智能手机、折叠屏设备、智能穿戴的主板测试点(覆盖射频、基带、电源信号);
  2. 汽车电子:车载ECU、传感器模块的信号测试点(满足宽温/振动环境);
  3. 工业控制:PLC、伺服驱动器的I/O信号测试点;
  4. 通信设备:5G基站板卡、光模块的高频信号测试点(适配高密度布局)。

二、关键设计与参数特点

RCWCTE的核心优势集中在小尺寸、稳定接触、低成本三个维度:

1. 封装与空间效率

  • 结构:铁环型贴片(无塑胶包裹),整体尺寸3.2mm×1.6mm,铁环直径3.2mm;
  • 空间优势:无塑胶设计降低PCB高度(约0.8mm),比带塑胶测试点节省30%布局空间,适配折叠屏、5G基站等高密度场景。

2. 接触与电气性能

  • 铁环接触:环形面积大,探针接触不易偏移,接触阻抗典型值<10mΩ;
  • 耐插拔性:支持≥1000次探针插拔,无明显接触不良;
  • 电气参数:额定电流1A(峰值2A),工作电压≤24V,满足常规设备测试需求。

3. 工艺兼容性

  • 材质:铁环表面镀锡(可选镀金,抗氧化更强),焊接性优异;
  • 焊接工艺:兼容SMT回流焊(260℃±5℃/≤30s)、波峰焊(245℃±5℃/≤5s),无塑胶变形风险。

三、可靠性与环境适应性

RCWCTE经过多项可靠性测试,满足不同场景要求:

1. 环境耐受能力

  • 工作温度:-40℃~+125℃(工业级/汽车级标准);
  • 存储温度:-55℃~+150℃;
  • 耐湿性能:85℃/85%RH环境下1000小时,电气性能无下降。

2. 可靠性验证

  • 插拔寿命:1000次插拔后,接触电阻变化≤5%;
  • 盐雾测试:96小时试验后,铁环无氧化腐蚀;
  • 振动测试:10~2000Hz振动下,无脱落/接触不良。

四、选型与使用注意事项

1. PCB焊盘设计

  • 焊盘:圆形,直径≥3.5mm(适配3.2mm铁环);
  • 间距:相邻测试点≥0.5mm(避免短路);
  • 布局:靠近待测信号节点,减少测试线干扰。

2. 探针匹配

  • 探针直径:0.8mm~1.2mm(常规ICT探针规格);
  • 接触深度:≥0.5mm(保证充分接触)。

3. 替代参考

  • 带塑胶绝缘需求:选KOA带塑胶测试点系列;
  • 大电流需求(≥2A):参考KOA大电流测试点产品。

五、市场价值与客户反馈

RCWCTE凭借高性价比、小尺寸、稳定可靠,已成为中高端厂商首选:

  • 汽车客户:某车载ECU厂商用其替代传统测试点,宽温环境下1200次测试无不良,满足车规要求;
  • 消费电子客户:某折叠屏厂商节省20%空间,布置15个测试节点,覆盖射频/基带信号;
  • 工业客户:某PLC厂商降低15%物料成本,提升生产测试效率。

该产品适用于对空间、成本、可靠性有平衡要求的电子设备,是PCB测试节点的高性价比选择。

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
