High Speed LiteTouch Solderless RF/Coaxial Printed Circuit Board Connectors Slide 4

As operating frequency requirements creep higher and higher, the PCB substrate layers become thinner and thinner requiring a lower force engagement on the boards. To support frequencies above 30 GHz, low dielectric constant PCB substrates are trending thinner than 0.010” to transmit successfully. As printed circuit board substrates become thinner to support higher operating frequencies, coaxial connectors need to evolve as well. Conventional ‘compression style’ solderless coaxial connectors depend on compressing the trace/substrates to make electrical contact. This compression becomes increasing impactful on the impedance of the transition from coaxial connector to PCB as the substrates get thinner. In response to this issue, SV Microwave developed the proprietary LiteTouch connector series to address this issue by significantly reducing the contact force on the trace required for a good electrical connection. The SV uses a pogo-pin style center contact that lightly touches the trace without damaging the circuit board.
