Frequently Asked Questions
How many positions and what pitch does the SEAF-40-06.0-S-06-2-A-K-TR provide for board-to-board connections?
The SEAF-40-06.0-S-06-2-A-K-TR provides 240 positions arranged on a .050" (1.27 mm) pitch open-pin-field array. This high-density configuration supports routing of differential pairs, single-ended signals, and power pins across a compact board stacking interface at a 6.0 mm stacking height.
What contact finish does SEAF-40-06.0-S-06-2-A-K-TR use, and how does it affect signal reliability?
The mating contacts of SEAF-40-06.0-S-06-2-A-K-TR are finished with 30 µin of gold over 50 µin of nickel, providing low contact resistance and high corrosion resistance. Gold plating at this thickness ensures reliable electrical performance over thousands of mating cycles, critical for high-speed differential signal integrity at multi-Gbps data rates.
Which high-speed signal applications benefit most from the SEAF-40-06.0-S-06-2-A-K-TR open-pin-field design?
The open-pin-field layout of SEAF-40-06.0-S-06-2-A-K-TR is ideal for FPGA mezzanine cards, high-speed backplane daughter cards, and SerDes-based communication boards operating at data rates up to 56 Gbps per differential pair. Designers can freely assign up to 240 pins for signal, power, and ground, optimizing impedance and crosstalk control without a fixed pinout constraint.
What stacking height does SEAF-40-06.0-S-06-2-A-K-TR provide, and when is this height preferred over shorter alternatives?
The SEAF-40-06.0-S-06-2-A-K-TR provides a 6.0 mm board stacking height, which accommodates taller components such as voltage regulators, inductors, or heat sinks mounted on the lower PCB. This 6.0 mm height is preferred in multi-board systems with component height clearance requirements, compared to shorter 2.0 mm or 4.0 mm stack options used in ultra-compact designs.
