Key Features & Advantage:

SMT Stacking Solution: Combines board-spacing capability with surface mount technology, enabling vertical PCB-to-PCB mating without the need for through-holes, saving critical bottom-layer PCB space.
Superior SMT Coplanarity: Designed with an optimized SMT footprint supporting strict coplanarity control within 0.15mm Max, ensuring flawless solder paste contact and eliminating soldering defects.
Dual-Insulator Layout Options: Offers both SV and SN series configurations with defined insulator heights (H=1.5mm or H=2.54mm) and customizable pin dimensions to easily adapt to customized mezzanine heights.
Reflow Oven Ready: Formulated from premium LCP or NL6T high-temperature thermoplastics (UL 94V-0), seamlessly enduring standard lead-free reflow soldering profiles.
Optimized for Automation: Available in Tape & Reel with Cap packaging options, designed specifically for seamless, high-speed pick-and-place automated assembly.
