Frequently Asked Questions
How does the hermaphroditic design of the LSHM-140-03.0-L-DV-A-N-TR simplify board stacking in embedded systems?
The LSHM-140-03.0-L-DV-A-N-TR uses hermaphroditic contacts, meaning the same 40-position connector is placed on both mating boards. This eliminates the need to stock separate male and female parts, simplifying BOM management and reducing procurement complexity in multi-board embedded computing and portable electronics designs.
What stack height does the LSHM-140-03.0-L-DV-A-N-TR provide, and how does it affect system packaging?
The LSHM-140-03.0-L-DV-A-N-TR is rated for a 3.0 mm board-to-board stack height. This ultra-low profile makes it suitable for thin, compact enclosures in portable medical devices, industrial handheld equipment, and multi-PCB assemblies where total system height must be minimized.
Is the LSHM-140-03.0-L-DV-A-N-TR RoHS compliant and compatible with lead-free soldering processes?
Yes, the LSHM-140-03.0-L-DV-A-N-TR is RoHS compliant and uses matte tin (Sn) over nickel (Ni) barrier termination, which is compatible with standard lead-free SMT reflow processes. Its 40-pin board stacking connector construction meets current environmental compliance requirements for commercial and industrial electronics manufacturing.
What body dimensions should PCB layout engineers consider when placing the LSHM-140-03.0-L-DV-A-N-TR?
The LSHM-140-03.0-L-DV-A-N-TR has a body length of 0.972 inch, breadth of 0.196 inch, and depth of 0.175 inch. PCB layout engineers should allocate keep-out zones around these 40-position stacking connectors and verify peg hole positions for the board mounting option during footprint placement.
