镀金触头可靠性
触头采用≥0.3μm金镀层,相比锡镀层更耐氧化、耐腐蚀,长期使用后接触电阻稳定(≤20mΩ),避免信号中断或功率损耗。
SMD封装提效
表面贴装设计兼容SMT自动化生产线,贴装精度≤0.1mm,可通过回流焊一次完成,提高生产效率并降低人工成本。
结构稳定性增强
LCP绝缘壳体耐高温变形(回流焊峰值温度≤260℃);部分型号配备防错插凸点/凹槽,避免公母座反向插拔损坏。
该连接器聚焦PCB板间信号/小功率传输,典型场景包括:
该产品平衡了小型化与可靠性,是高密度电子设备板间连接的高性价比选择,星坤提供定制化(PIN数、镀层厚度)与技术支持,满足不同客户需求。
Request for quote
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.
