New Samtec matched impedance micro interfaces (QTH/QSH Series) on .5mm (.0197") pitch are available with a choice of 60, 120, 180, an 250 I/Os. The discrete ground plane between rows is surface mounted for a 100% surface mount system that eliminates the need for through-hole penetrations found with other systems.

These Samtec high speed interconnects are fully tested for 50 ohm systems for impedance, VSWR, attenuation, crosstalk and propagation delay at frequencies from 10 MHz to 1Gig. They provide a low profile board-to-board spacing of only .197" (5mm) between boards. Edge mount, elevated, differential pair and cable versions of these interfaces are under development.

Samtec provides a full line of micro pitch interfaces for quiet and high speed applications including .025" (.635mm) pitch with up to 250 I/Os (QTS/QSS Series), and .8mm (.0315") pitch with up to 200 I/Os (QTE/QSE Series).
