TE Connectivity(泰科电子)型号 1775862-2 是一款面向板对板连接的低剖面 mSATA / Mini PCI Express 母座,采用卧贴(right-angle / low-profile)SMD 封装,适用于板上安装的 mSATA/mini PCIe 模块连接。该产品为 52 针、中心线间距 0.8 mm 的高密度连接器,堆叠高度(板对板间距)为 5.2 mm,带定位柱以增强机械强度与定位精度,触点经过镀金处理以确保可靠的电气接触与耐腐蚀性。总体设计旨在满足嵌入式储存模块与 mini PCI Express 外设在有限空间内的高速互连需求。
该连接器采用低剖面卧贴设计,堆叠高度 5.2 mm,非常适合对高度有严格限制的单板系统或模块化设计。带柱结构提供了可靠的定位与机械支撑,减少模块插拔或振动时的应力集中。作为 SMD 元件,推荐使用与之匹配的 PCB 封装设计(建议参考制造商所提供的推荐焊盘与 3D 模型),并在回流焊工艺中遵循合适的温度曲线以保证焊点可靠性。
设计时需关注:
0.8 mm 的高密度间距和 52 针配置,使该连接器适用于承载 PCI Express 类的高速差分信号(mSATA 基于 mini PCIe 物理规范)。镀金触点可提供良好的接触电阻和长期可靠性,有利于维持高速传输时的信号稳定性。
在电路板设计与布线时,应注意:

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.
