Card Edge Connector
Industrial, IT Datacom
Crafted for tough industrial working scenarios, this surface mount Mini PCIe connection component serves as a core linking part for electronic hardware expansion and data transmission. Developed with strict factory technical standards, it adopts refined fabrication craft and durable raw material matching, effectively overcoming common defects seen in ordinary connecting pieces such as loose contact, weak welding firmness and narrow applicable range. It stably supports long-hour continuous operation and accurate size assembly, fitting various electronic equipment with rigorous connection demands.
All physical dimensions follow official technical blueprints, keeping linear and angular deviation within the range from ±0.15mm to ±0.40mm. Accurate outline design avoids contact failure brought by size mismatch. It perfectly matches two mainstream specification circuit cards, and runs smoothly during automatic assembly processing without installation failure issues.
The outer shell is made of high heat resistant polymer material, reaching UL94V-0 fire safety grade with classic black appearance. Conductive pins and positioning columns adopt high purity copper alloy raw material. The whole structure can resist high temperature impact in welding process and external mechanical extrusion, maintaining steady physical shape for long service life.
Different areas are equipped with targeted metal coating schemes. Conductive contact surface provides multiple gold plating thickness choices to guarantee smooth signal conduction. Welding end and positioning part are covered with thick nickel base layer plus anti-rust coating. The overall structure gains strong anti-abrasion, anti-oxidation and moisture-proof capacity to adapt complex working surroundings.
One single connector can be matched with two widely used circuit card sizes in the industry. It supports installation and use of 50.8mm & 48.05mm full-size cards, as well as 26.8mm & 23.9mm half-size cards. Flexible compatibility cuts hardware matching troubles and enriches equipment design flexibility.
Designed based on circuit board surface installation benchmark, 0.8mm standard pin spacing matches universal 180-degree patch installation mode. Reserved reasonable gap space effectively stops welding overflow and position deviation. The structure fully adapts lead-free welding production flow, convenient for large-scale standardized manufacturing.
Built-in hardware structure supports normal operation of Mini Card 457 and mSATA two mainstream transmission protocols. It simplifies internal circuit layout design and reduces accessory configuration quantity, suitable for integrated hardware design combining data storage and function expansion.
