Frequently Asked Questions
For an FPGA mezzanine application needing 88 I/O signals, how does SFM-144-02-SM-D-A-K manage signal integrity at high data rates?
The SFM-144-02-SM-D-A-K supports differential pair routing across its 88 positions at 0.050" pitch, with controlled-geometry contacts that maintain characteristic impedance near 50 ohms. This allows high-speed LVDS and SERDES interfaces operating at 1 Gbps to 3.125 Gbps per lane to transit the connector with minimal insertion loss and crosstalk between adjacent pairs.
What thermal limit applies to SFM-144-02-SM-D-A-K during PCB reflow assembly, and how does this affect solder joint quality?
The SFM-144-02-SM-D-A-K is rated for reflow soldering at peak temperatures up to 260°C, compliant with JEDEC J-STD-020 lead-free reflow profiles. At this temperature, all 88 surface mount solder joints reach proper wetting simultaneously, producing consistent joint quality that eliminates the cold-joint risk associated with selective wave soldering of fine-pitch connectors.
When is SFM-144-02-SM-D-A-K a stronger choice than SFM-143-L2-H-D-A-K for expanding a mezzanine I/O count?
When a design requires 88 signal contacts rather than 86, SFM-144-02-SM-D-A-K provides 2 additional positions at the same 0.050" pitch, accommodating one extra differential pair or 2 single-ended signals without changing the board-to-board stack height. This is useful when routing a standard 8-lane PCIe interface plus 72 general-purpose I/Os, which totals 88 contacts and exactly fills SFM-144-02-SM-D-A-K's capacity.
