Samtec Q Strip^® mezzanine connectors are designed for high-speed board-to-board applications where signal integrity is essential.   

Q Strip connectors feature surface mount signal contacts as well as a surface mount ground plane between the two rows of signal pins for improved electrical performance.

The integral ground plane can be used to maximize bandwidth and signal integrity, or it can be used as a power plane.  If used for power, the ground plane can handle 23 to 25 amps, depending on the product series.  These connectors are rated at 28 Gbps at a 5mm stack height.  

Q Strip products are available on three different pitches: 0.50 mm pitch, the QTH and QSH series 0.80 mm pitch, the QTE and QSE series and 0.635 mm pitch, the QTS and QSS series  
They are available in vertical (parallel), perpendicular (right angle, or 90°),  and horizontal (or coplanar) designs.

Mated connector sets are available in 8 different stack heights from 5 mm (.197") to 25 mm (.984”).

Up to 180 total I/Os are available, depending on the centerline.  Q Strip products can be routed as single ended or in differential pair configurations.  They are also available with every third pin pulled for differential pair applications (designate the -DP option in the part number). 

Standard features include polarization, alignment pins for proper placement on the PCB, guide posts on right angle and edge mount designs, weld tabs to increase the mechanical strength of the part to the board, and optional latching clips.  All Q Strip products are RoHS compliant.

Common applications for Q Strip products include, but are not limited to, servers, network systems like routers, switches, hubs, bridges, industrial controls and equipment, computers and peripherals, test and measurement, multi-chip modules, and high resolution graphics devices, to name a few.

A complete line of high speed cable assemblies that mate with Q Strip board level connectors is also available.
