PCB connectors provide an ultra-low mated stack height

Samtec now offers its SLH/TLH Series PCB-to-board (B2B) connectors, which provide an ultra-low mated stack height down to 2mm (0.078") and support 28Gbps NRZ performance. These connectors are part of the company's Ultra Micro line of products, which maximise overall space and offer reliable connections in high-data-rate rugged environments such as automotive, industrial IoT, robotics, and defence and aerospace.

For overall space savings, in addition to an extremely low 2mm stack height, the SLH/TLH mated board-to-board connector set has a narrow width of 4.7mm (0.185") and a dense length of 9mm (0.356") with 20 total positions. Higher-density signal routing is available with 40 or 60-total pins connectors at slightly longer lengths. High pin density of the stacking board-to-board connectors is enabled by using a microblade and beam contact system, which has a blade on one side and a beam on the other, on a 0.5mm (0.0197") ultra-fine pitch.

The pick-and-place polyimide film pad enables precision placement onto the PCB. It allows a vacuum machine to lift the SMT board-to-board connector and place it onto a PCB. The company makes adhering to tight processing tolerances for ultramicro interconnects easy by making supporting documentation accessible on its website.
