SMN-303S-ACP7是讯普(XUNPU) 针对轻薄化终端推出的NanoSIM卡专用自弹式卡座,采用表面贴装(SMD)封装,聚焦“便捷操作+紧凑空间+宽温适配”三大核心需求,集成插卡检测功能,覆盖消费电子、工业终端、物联网设备等多场景应用。
采用“弹簧+卡扣联动”设计:插入SIM卡时,卡扣自动锁定(锁定力度≥8N);按压卡片顶部,弹簧弹出(弹出高度≥1mm),避免传统掀盖式卡座的卡扣松动、工具依赖问题,单手操作效率提升30%。
本体高度1.37mm采用精密注塑+冲压一体化工艺,外壳选用耐高温ABS+PC材料(耐温120℃以上),抗冲击性强;引脚镀金处理(厚度≥0.3μm),提升接触可靠性与抗腐蚀能力(盐雾测试96小时无氧化)。
内部检测机构与卡触点同步联动,仅当SIM卡插入到位时触发信号,避免“半插卡误判”或“卡松动无响应”,终端通信稳定性提升20%。
适配智能手机(轻薄机型)、智能手表、平板等设备:超薄设计满足穿戴设备“毫米级空间要求”,自弹式换卡无需拆卸后盖,提升用户体验。
覆盖手持PDA(快递/仓储)、车载导航、车联网T-Box:宽温范围适配户外-40℃低温与车载+85℃高温,抗振动设计(振动测试10Hz~2000Hz无故障)避免设备运行中卡松动。
支持智能POS机、无线网关、智能电表:稳定电气性能(接触电阻≤20mΩ)保证长期通信可靠,自弹式设计方便运维人员快速换卡(无需工具,操作时间≤2秒)。
SMD封装兼容主流贴片机(Yamaha、Siemens),贴装精度±0.1mm,回流焊温度曲线符合J-STD-020标准,焊接良率≥99.5%。
故障卡座可通过热风枪拆卸(SMD封装),更换成本低;自弹式结构无需工具换卡,减少终端维护时间。
SMN-303S-ACP7凭借超薄紧凑、自弹便捷、宽温可靠三大核心优势,成为轻薄化终端、工业与物联网设备的理想SIM卡连接方案。讯普在连接器领域的工艺积累,进一步保障了产品的一致性与长期稳定性,适配多场景下的SIM卡通信需求。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
