II. Core Product Features
Wide range of fine pitches for various density requirements
Covering 1.0mm, 1.27mm and 2.0mm fine pitches to precisely match different circuit layout densities:
1.0mm ultra-fine pitch increases pin density by 50%, ideal for smart wearables and micro sensor modules;
1.27mm industrial-grade fine pitch balances density and stability, widely used in industrial motherboards and communication modules;
2.0mm pitch balances density and operability, suitable for portable medical devices and automotive electronics sub-boards.
All versions support single-row / dual-row structures with 2–50 pins, and can be flexibly customized to meet various signal and power transmission demands.
Optimized SMT design for automated mass production
Standard SMD design with precise pad sizes matching mainstream pick-and-place nozzles, ensuring mounting accuracy ≤±0.05mm for seamless integration into automatic production lines.
Housings are made of high-temperature resistant LCP material, capable of withstanding reflow soldering at 260℃±5℃ without deformation, melting or performance degradation for 10 seconds above 245℃. Terminals feature special high-temperature anti-oxidation plating to prevent peeling and oxidation during soldering, avoiding cold joints and false joints with a soldering yield above 99.9%.
Highly stable connection for accurate and reliable signal transmission
Terminals are made of high-purity oxygen-free copper with gold plating ≥0.3μm, contact resistance ≤15mΩ, excellent oxidation and wear resistance, effectively reducing signal loss.
Dual-row female headers adopt staggered terminals and grounding shielding, with impedance controlled at 50Ω±5Ω, supporting high-frequency transmission over 10Gbps and eliminating crosstalk between channels.
Internal contacts use a dual-point clamping structure with insertion-extraction force precisely controlled at 0.5–1.0N per pin, ensuring smooth operation without looseness or deformation. With outstanding elastic recovery, the service life exceeds 8000 cycles while maintaining stable contact force.
Compact structure for maximum space saving
In response to miniaturization requirements, products adopt low-profile or ultra-thin board-mounted designs. The 1.0mm pitch version has an overall height as low as 1.8mm, saving 70% vertical space compared with traditional headers, ideal for compact PCBs in smart watches and micro sensors.
One-piece injection-molded housing enhances structural strength and reduces lateral area by 30%, supporting dense multi-port layout and enabling lightweight and miniaturized end products.
Wide temperature resistance for harsh environments
Products operate stably in a wide temperature range of -40℃ to 125℃. The housing remains crack-resistant at low temperatures and reliable at high temperatures, suitable for automotive, industrial and outdoor applications.
Made of UL94 V-0 flame-retardant engineering plastic, with insulation resistance ≥1000MΩ and withstand voltage ≥AC500V, effectively preventing short circuits and ensuring equipment safety.
