Frequently Asked Questions
What pitch and contact count does the QTE-020-01-L-D-A-K provide for high-density board-stacking designs?
The QTE-020-01-L-D-A-K uses a 0.80 mm pitch with 20 positions in a dual-row configuration. This fine pitch allows a contact field length under 8 mm, enabling dense board-stacking assemblies in wireless modules, compact computing boards, and data acquisition systems where PCB real estate is limited.
How does the ground-plane architecture of the QTE-020-01-L-D-A-K benefit high-speed signal transmission?
The integrated ground-plane design in the Q Strip series provides controlled impedance along each signal contact, reducing crosstalk and reflections at multi-GHz data rates. This is critical for differential pairs in PCIe, USB 3.x, and high-speed LVDS links on mezzanine daughter cards, where maintaining consistent 50-ohm or 100-ohm impedance through the connector is essential for eye-diagram compliance.
For a compact RF daughter card assembly, how does the QTE-020-01-L-D-A-K ensure accurate board-to-board alignment?
The -K suffix designates locating posts integrated into the connector body, which engage alignment holes on the mating PCB during reflow soldering. This feature maintains a positional tolerance better than 0.1 mm between the two boards, preventing skew that could degrade impedance matching and increase insertion loss at frequencies above 1 GHz in RF front-end or FPGA mezzanine applications.
