Samtec has fully released its line of vertical solderless, compression mount connectors that incorporate precision alignment features. Spanning DC to 90 GHz, the new connectors are well suited for use in high frequency test and measurement applications and are available in full production quantities.

The connectors come standard with precision alignment features that are exclusive to Samtec and ensure peak connector performance. The solderless launch (where the connector is compressed onto the PCB using mounting hardware) allows for easy, field replaceable, cost-effective assembly to the PCB and eliminates possible performance degradation commonly found with solder reflow.

This new line of connectors includes both threaded and push-on interface types:

• 135 Series: 1.35 mm (90 GHz)
• 185 Series: 1.85 mm (65 GHz)
• 240 Series: 2.40 mm (50 GHz)
• 292 Series: 2.92 mm (40 GHz)
• GPPC Series, -CMM option: SMPM (65 GHz).

“In extremely high frequency test and measurement applications, compression mount connectors have become the connector of choice. Samtec has noticed that when compression mounting, slight misalignment between the connector and the landing pad can occur causing signal degradation. While at lower frequencies this degradation is minor, at high frequencies it can become problematic yet very difficult to detect. This has been observed even when mounting screws are tightened to proper torque specifications.” said Dan Birch global RF engineering manager at Samtec. “To prevent this issue, alignment features are now standard with all Samtec vertical compression mount RF products.”

For differential pair test and measurement applications, Samtec has released its vertical GPPC Series with a -CMM solderless option. It’s the only ganged, solderless connector of its kind in the industry. The push-on coupling design enables quick-attach for ease of use in a lab setting.
