Frequently Asked Questions
How many positions and what pitch does the SFM-142-02-L-D provide in its surface-mount package?
The SFM-142-02-L-D provides 84 total positions arranged in 2 rows with a 0.050" (1.27 mm) pitch, all in a surface-mount (SMT) package. This dense layout enables 84 independent signal connections between boards within a compact PCB footprint, supporting high pin-count applications such as FPGA mezzanine boards and data acquisition modules.
What advantages does the surface-mount termination offer over through-hole alternatives for the SFM-142-02-L-D?
Surface-mount termination allows the SFM-142-02-L-D to be placed and reflowed alongside other SMT components during standard PCB assembly, eliminating the need for wave soldering or manual through-hole insertion. This reduces assembly cost, improves placement accuracy at 0.050" pitch, and results in a lower connector profile that saves vertical board space in stacked module designs.
In what industries and product types is the SFM-142-02-L-D high-reliability socket strip typically deployed?
The SFM-142-02-L-D is typically deployed in industrial computing, telecommunications equipment, FPGA evaluation platforms, and high-speed test-and-measurement systems. Applications requiring 84 signal lines routed between a mezzanine card and a baseboard via a 0.050" pitch socket strip benefit from its high-reliability contact design and stable performance across temperature ranges and mating cycles.
How does the dual-row design of the SFM-142-02-L-D contribute to PCB space savings?
By placing 84 contacts in 2 rows on a 0.050" (1.27 mm) pitch, the SFM-142-02-L-D routes twice as many signals per unit of connector length compared to a single-row arrangement. This dual-row format significantly reduces the board edge length occupied by the connector, freeing PCB area for routing, decoupling capacitors, and other components around the 84-pin interface.
