0.4 mm Pitch SMT Board to Board Plug, 1.14mm Height
Introduction:
This 0.4 mm pitch SMT board-to-board plug delivers a high-density, vertical surface-mount interconnect solution for compact electronic assemblies. Designed with a dual-row configuration supporting 20 to 120 positions, this male connector addresses the demanding routing requirements of modern mobile devices, wearables, and portable instrumentation. The ultra-low 1.14 mm seated height optimizes space utilization in stacked PCB architectures, while the vertical mounting orientation provides straightforward placement during automated assembly processes.
Constructed with a copper alloy contact system plated with gold flash, the connector ensures reliable signal integrity and corrosion resistance over repeated mating cycles. The high-temperature thermoplastic insulator withstands reflow soldering profiles without deformation, and the material set meets UL 94 V-0 flammability requirements for enhanced safety. Operating reliably across a -40°C to +85°C temperature range, this component supports diverse environmental conditions while maintaining consistent electrical performance.
