Frequently Asked Questions
What components can fit between two stacked boards when LSHM-110-02.5-L-DV-A-S-TR sets a 2.5 mm inter-board spacing?
A 2.5 mm board-to-board gap limits component height on the mating-face side to approximately 1.8 mm to 2.0 mm after accounting for PCB thickness and solder joint clearance. This allows standard 0402 and 0201 passives, thin MLCCs up to 0.5 mm height, and low-profile flip-chip ICs in LGA packages, but excludes most standard WLCSP packages above 0.5 mm and typical electrolytic capacitors, constraining the component palette to compact SMD parts for the 20-position dual-row stacking interface.
How does the gold contact finish on LSHM-110-02.5-L-DV-A-S-TR benefit a wearable device that undergoes frequent module swaps?
Gold plating on the mating contacts maintains a low and stable contact resistance below 30 mΩ across hundreds of insertion and extraction cycles, unlike tin contacts that form oxide layers and increase resistance after 20 to 50 cycles. For a wearable device with a swappable sensor module replaced every 3 to 6 months over a 5-year product life, the gold finish on LSHM-110-02.5-L-DV-A-S-TR supports at least 10 replacement cycles while keeping signal integrity intact across all 20 positions.
How does the 1-week lead time for LSHM-110-02.5-L-DV-A-S-TR affect prototype procurement compared to longer-lead SAMTEC stacking connectors?
A 1-week factory lead time means engineering teams can order LSHM-110-02.5-L-DV-A-S-TR and have parts in hand within 2 to 3 weeks including distributor handling and shipping, compared to 8 to 10 weeks for custom or non-stocked SAMTEC stacking connector variants. For prototyping sprints targeting a 4-week design validation cycle, the short lead time keeps the connector off the critical path and allows board bring-up to proceed on schedule without expediting fees.
What mating connector pairs with LSHM-110-02.5-L-DV-A-S-TR, and how is the 2.5 mm stack height achieved in the assembled pair?
LSHM-110-02.5-L-DV-A-S-TR mates with the corresponding LSHM plug series from SAMTEC, designed for the same 20-position dual-row 0.50 mm pitch footprint. When the socket and plug are fully engaged, the combined stack height reaches 2.5 mm, with the socket contributing approximately 1.5 mm and the plug header contributing 1.0 mm. This controlled 2.5 mm dimension is maintained within ±0.1 mm, ensuring predictable board-to-board clearance across the assembled module.
