Description

Our SMT Dual Row Surface Mount Male Pin Header Connector 2.54mm Pitch PCB 80-Pin Reflow Compatible represents a precision-engineered interconnect solution designed for reliable board-to-board and wire-to-board connections in demanding electronic applications. Manufactured with high-temperature PA6T thermoplastic insulation and precision-stamped brass contacts, this connector series delivers consistent electrical performance across a wide range of operating conditions. Every connector undergoes rigorous quality inspection including contact resistance measurement, insulation resistance testing, and visual inspection under magnification to guarantee conformance to international standards.

The contact system utilizes high-conductivity brass alloy pins with selective gold or tin plating over nickel underplate, providing superior corrosion resistance and reliable mating cycles exceeding industry benchmarks. Our automated assembly lines employ precision insertion technology that ensures consistent pin alignment and coplanarity, critical factors for successful PCB mounting in high-volume production environments. The insulator body is molded from UL94V-0 rated PA6T material reinforced with 30% glass fiber, offering exceptional thermal stability up to 105°C continuous operating temperature while maintaining dimensional accuracy.

Key Features
  • Full SMT Process Integration: Dual row SMT design eliminates mixed-technology assembly requirements, enabling 100% surface mount production with reduced process steps and faster cycle times
  • Optimized Solder Footprint: PCB land pattern designed per IPC-7351 guidelines with extended toe fillets, ensuring robust solder joint formation verified through X-ray inspection and cross-section analysis
  • High-Temperature Construction: PA6T insulator with 30% glass fiber rated for multiple lead-free reflow cycles, maintaining mechanical integrity and electrical performance through peak temperatures of 260°C
  • Anti-Tombstoning Design: Balanced thermal mass distribution between both rows prevents tombstoning defects during reflow, with symmetrical pad geometry optimized through thermal profiling studies
  • Automated Inspection Ready: Gull-wing lead configuration provides clear solder fillet visibility for both manual and automated optical inspection systems, reducing post-reflow QC cycle time
  • Board-Level Reliability: Validated through temperature cycling (-40°C to +125°C, 1000 cycles) and mechanical shock testing per IEC 60068-2-27, ensuring field reliability in harsh operating environments

Applications

Dual row SMT pin headers are specifically engineered for high-density PCB assemblies in telecommunications infrastructure including 5G small cell radio units, optical line terminal subscriber boards, and network switch fabric modules where board space optimization is critical. The dual row SMT format enables compact interconnect solutions for portable medical imaging equipment, drone flight controller boards, and advanced driver-assistance system (ADAS) sensor modules requiring reliable, vibration-tolerant surface mount connections. These connectors also serve as programming and debug headers on densely populated IoT gateway boards where vertical clearance constraints preclude through-hole alternatives.

Packaging & Quality Assurance

Packaged on 330mm diameter reels with 24mm wide embossed carrier tape, 400 pieces per standard reel. Reels are individually vacuum-sealed in moisture barrier bags meeting IPC/JEDEC J-STD-033 moisture sensitivity requirements. Each reel includes a humidity indicator card and desiccant pack. Outer case labeling includes 2D barcode for automated warehouse scanning, and we support EDI 856 advance ship notification with reel-level serialization for OEM supply chain integration.

Our manufacturing facility operates under ISO 9001:2015 certified quality management system with comprehensive traceability from raw material receiving through finished product shipment. Each production lot undergoes statistical process control monitoring, and certificate of conformance documentation is available upon request. We maintain substantial inventory of standard configurations to support just-in-time delivery requirements while offering flexible customization for specialized pin lengths, plating options, and packaging formats. Engineering samples are available within 48 hours for qualification testing, and our technical team provides application engineering support to assist with connector selection and PCB layout optimization. With over a decade of connector manufacturing expertise, we are committed to delivering interconnect solutions that exceed performance expectations while maintaining competitive pricing for volume production programs.
