Frequently Asked Questions
What stack height and position count does the LSHM-140-03.0-L-DV-A-S-K-TR provide for mezzanine designs?
The LSHM-140-03.0-L-DV-A-S-K-TR provides an 80-position dual-row interface with a 3.0 mm board-to-board stack height, allowing engineers to design compact mezzanine assemblies where vertical clearance between PCBs must be tightly controlled within ±0.2 mm tolerance.
Why is the shielded construction of the LSHM-140-03.0-L-DV-A-S-K-TR important for high-speed signal integrity?
The integrated shield in the LSHM-140-03.0-L-DV-A-S-K-TR attenuates electromagnetic interference between adjacent signal pairs, an essential feature when routing differential signals above 1 GHz through the 80-position connector array on densely packed mezzanine boards.
What does the peg board mounting option on the LSHM-140-03.0-L-DV-A-S-K-TR provide during assembly?
The peg mounting feature provides mechanical registration during PCB assembly and pre-mating alignment, preventing misregistration of the 80 contacts across the dual-row array. This reduces connector damage risk during hand and automated board-stacking operations and improves long-term mechanical retention.
How do the gold mating contacts differ from the matte tin termination on the LSHM-140-03.0-L-DV-A-S-K-TR?
Gold-plated mating contacts (typically 30 µin / 0.76 µm gold) ensure low and stable contact resistance at the board-to-board interface across many mating cycles, while matte tin termination on the PCB pads provides good solderability with standard lead-free solder alloys at 260°C peak reflow temperature.
In which high-reliability system environments is the LSHM-140-03.0-L-DV-A-S-K-TR a preferred board stacking solution?
The LSHM-140-03.0-L-DV-A-S-K-TR is preferred in defense electronics, aerospace avionics, and industrial embedded computing systems where shielding against EMI, precise 3.0 mm stack height control, and 80-channel signal density are simultaneously required in a single high-reliability connector solution.
