- Integrated ground plane design reduces cross-talk and signal skew, supporting high-speed differential pair routing above 10 Gbps
- Gold flash mating contacts over phosphor bronze provide reliable low-resistance connections with consistent insertion force across 100+ mating cycles
- ELP (Extended Life Plating) feature and RoHS-compliant tin-over-nickel termination ensure long-term reliability in demanding board stacking applications
Applications
The QTE-020-07-F-D is designed for high-speed board-to-board stacking in FPGA daughter cards, network switch line cards, and server mezzanine modules where 0.80 mm pitch connectivity supports data rates exceeding 10 Gbps per lane. Its integrated ground plane header architecture minimizes signal integrity degradation in dense PCB stacks used in telecom and data center equipment. The 20-position dual-row layout suits compact interconnects in storage accelerator cards, optical transceiver modules, and high-bandwidth embedded computing platforms.

Frequently Asked Questions
What pitch and signal density does the QTE-020-07-F-D offer for board stacking designs?
The QTE-020-07-F-D uses a 0.80 mm pitch with 20 positions in a dual-row layout, providing 40 contacts in a compact board stacking footprint. This fine pitch enables high-density interconnects in FPGA mezzanine cards and switch line cards where PCB space is constrained to less than 20 mm wide.
How does the ground plane design of the QTE-020-07-F-D benefit high-speed signal integrity?
The integrated ground plane in the QTE-020-07-F-D Q Strip header reduces impedance discontinuities and inter-pair cross-talk at data rates above 10 Gbps. By referencing each signal contact to a nearby ground, the connector maintains controlled 50 Ω or 100 Ω differential impedance, which is critical for PCIe Gen 3/4, USB 3.x, and 25G Ethernet board stacking applications.
What contact material and plating does the QTE-020-07-F-D use to ensure long mating life?
The QTE-020-07-F-D uses phosphor bronze contacts with gold flash mating surfaces and tin-over-nickel barrier termination. Phosphor bronze provides spring-back force for consistent contact resistance below 30 mΩ across 100+ insertion cycles, while gold flash prevents oxidation on the mating interface for reliable electrical performance in board stacking systems.
When should a designer choose QTE-020-07-F-D over a wider-pitch board stacking connector?
The QTE-020-07-F-D is the preferred choice when PCB routing space allows only 0.80 mm pitch and the design requires 20 high-speed differential pairs or single-ended signals at data rates above 5 Gbps. Wider-pitch connectors such as 1.00 mm or 1.27 mm alternatives are appropriate for lower-speed I/O below 1 Gbps where the ground plane density of the QTE-020-07-F-D is unnecessary.
