Samtec Q Strip® connectors are designed for high speed board-to-board applications where signal integrity is essential. The Q Strip connectors have surface mount signal contacts as well as a surface mount ground plane between the two rows of signals for improved electrical performance.
Q Strip products are available on three different pitches:
By the way, the 0.50 mm pitch versions are the most popular, followed by the 0.80 mm pitch.
Integral Ground / Power Plane
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 – 25 amps, depending on the series.
Single Ended, Differential Pair
These connectors are rated at 28 Gbps (14 GHz) at a 5mm stack height. The connectors can be routed as single ended or in differential pair configurations. Versions are also available for differential pair applications. These are called Q Pairs®, and it’s the –DP option in the part number.
Design Flexibility and Variety
Mated sets of Q Strip connectors are available in seven different stack heights from 5 mm to 25 mm. By the way (again), the lower profile 5 mm stack heights are the most popular.
They are available in vertical (parallel), perpendicular (right angle, or 90°), and horizontal (or coplanar) designs. Depending on centerline, up to 180 total I/Os are available.
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, optional latching clips, and of course everything is RoHS compliant.
Q Strip products are ubiquitous; common applications include servers, network systems (routers, switches, hubs, bridges), industrial computers, test and measurement, multi-chip modules, and high resolution graphics, to name a few.
