Card Edge Connector
Industrial, IT Datacom
Manufactured by CONSHARE, this vertical 180-degree edge card connector is developed for high-density compact PCB interconnection scenarios. Featuring exclusive C-shaped SMT solder pins and 2-row ×70pin dense layout, the component balances miniaturized installation space and long-term circuit transmission reliability. Optimized to adapt diversified automated SMT production workflows, the connector meets industrial-level temperature and electrical standards, becoming a preferred interconnect solution for medium-to-high precision electronic equipment across automation, medical electronics and new energy sectors.
All electrical indicators pass standardized industrial reliability testing to guarantee stable continuous operation:
Single contact rated working current: 3A, satisfying most power and signal mixed transmission demands
Withstand voltage: 500V AC, effectively prevent instantaneous voltage breakdown under abnormal circuit fluctuation
Max contact resistance ≤30mΩ & insulation resistance ≥1000MΩ, minimize signal attenuation during long-term service
Wide working temperature range: -40℃ ~ +105℃, adapts sealed cabinet high-temperature environment and low-temperature outdoor storage conditions
Focus on practical installation-related core dimension parameters while discarding redundant outline sizes:
Standard center pitch: 0.80mm, mainstream high-density layout specification to save PCB layout area
Vertical plastic body height:7.8mm, fit limited-height stacked board assembly space
C-type solder pin adopts standardized chamfer design with controlled dimensional tolerance within ±0.10mm; whole connector mounting tolerance limited to ±0.05mm for seamless PCB matching
Optimized material and selective electroplating formulation oriented to cost and performance balance:
Insulating body: UL94V-0 black high-temperature LCP, outstanding heat resistance against lead-free reflow soldering impact
Contact raw material: high elastic phosphor bronze, outstanding anti-fatigue property after frequent plugging and unplugging
Selective differential plating: 3µ” hard gold exclusively on contact mating area for stable contact performance; solder tail finished with pure tin plating to boost soldering liquidity, nickel base layer fully covered underneath terminals for stronger plating adhesion
Different from traditional straight pin edge connectors prevailing on the market, CONSHARE self-developed curved C-shaped solder tail enlarges PCB soldering bonding area. The curved structure can offset thermal expansion discrepancy between metal pin and FR-4 circuit board during high-temperature reflow, greatly cutting cold solder and desoldering failure probability especially for high pin count 2×70pin products during automated mass production.
Custom-formulated black LCP raw material can sustain peak reflow temperature up to 260℃ without deformation or volatile gas precipitation, resolving the common industry defect of plastic shrinkage causing pin offset after high-temperature soldering. Added anti-UV ingredient also expands application possibility for equipment installed in open-air control cabinets.
Instead of full gold plating on entire terminals, CONSHARE only implements gold coating on the wear-prone contact insertion part. Tin plating applied on solder legs cuts excessive precious metal cost for buyers without compromising mating stability, a targeted structural optimization specially designed for multi-pin high-cost edge card connectors.
Relying on in-house precision mold development capability, we tighten the whole product’s mounting tolerance to ±0.05mm. The pre-verified PCB pad specification matches mainstream PCB manufacturing precision, helping clients save extra expense on secondary PCB revision during prototype development.
Benefiting from comprehensive electrical stability and wide ambient adaptability, this CONSHARE edge connector is widely applied in multiple precision electronic fields:
PLC mainboard and daughterboard internal interconnection for industrial automatic control equipment
Internal board connection of industrial Ethernet communication modules
Compact board wiring for portable medical diagnostic instruments
Internal PCB connection of small-capacity new energy BMS modules
Apart from in-stock 2×70pin standard model, CONSHARE supports personalized customization including different pin counts, variable selective gold thickness ranging from 1µ” to 30µ”, customized shell height and tape & reel packing per individual project’s PCB design requirement.
Standard finished products are packed with anti-static trays, perfectly suitable for automatic feeding equipment on customers’ SMT production lines and guarantee component safety during transit and storage.
