Frequently Asked Questions
How does the floating mount feature of TFC-141-02-FM-D-A help in backplane assembly applications?
The floating mount (FM) design of the TFC-141-02-FM-D-A allows up to ±0.5 mm of lateral misalignment to be absorbed during board mating. This is critical in backplane assemblies where multiple connectors must engage simultaneously across a board that may not be perfectly aligned, reducing the risk of bent pins, cracked solder joints, or connector damage during insertion.
How many signal positions does TFC-141-02-FM-D-A support, and why is dual-row layout advantageous at 0.050 inch pitch?
The TFC-141-02-FM-D-A provides 82 positions arranged in a dual-row configuration at 0.050 inch (1.27 mm) pitch. The dual-row layout halves the connector body length needed for 82 signals compared to a single-row design, resulting in a connector approximately 2.1 inches long instead of over 4 inches. This reduction in connector length frees board space for other components.
When should a designer choose TFC-141-02-FM-D-A over a fixed-mount equivalent for a multi-board chassis design?
Designers should choose TFC-141-02-FM-D-A over fixed-mount equivalents when inserting multiple PCBs into a chassis simultaneously, where cumulative mechanical tolerances across 82 contacts could cause alignment stress. The floating mount absorbs up to ±0.5 mm of misalignment, preventing solder joint cracking and reducing scrap rates in high-volume chassis assembly environments compared to rigid connectors.
