Frequently Asked Questions
How does the hermaphroditic design of the LSHM-120-L4.0-H-DV-A-N-K-TR simplify PCB stacking system design?
Since both mating boards use identical 40-pin connectors, the hermaphroditic design eliminates separate plug and socket variants, reducing inventory and simplifying BOM management while maintaining precise 4.0 mm stack height alignment for reliable board-to-board connections.
What data rates and signal performance does the LSHM-120-L4.0-H-DV-A-N-K-TR Razor Beam connector support?
The Razor Beam high-speed design of the LSHM-120-L4.0-H-DV-A-N-K-TR supports multi-GHz differential data rates, making its 40 pins at 0.50 mm pitch suitable for high-speed serial interfaces such as PCIe, LVDS, and USB 3.x across stacked PCB assemblies.
Which compact board stacking applications benefit most from the LSHM-120-L4.0-H-DV-A-N-K-TR's 4.0 mm stack height?
Compact 40-pin mezzanine modules, wireless communication boards, and high-density data acquisition systems benefit from the 4.0 mm board-to-board clearance, enabling tightly integrated multi-board assemblies within space-constrained enclosures without sacrificing signal integrity.
What reflow and assembly process does the LSHM-120-L4.0-H-DV-A-N-K-TR support in production?
Packaged in tape and reel format, the LSHM-120-L4.0-H-DV-A-N-K-TR supports automated pick-and-place SMT assembly and is rated for standard reflow soldering at up to 260°C peak temperature across its 40-pin hermaphroditic contact array.
