Pre-Tinned Push-On “Boss” PCB Connectors

Pre-Tinned Push-On “Boss” PCB Connectors

Amphenol CIT introduces the next evolution in “push-on” connector technology with a new product line of pre-tinned and embossed SMP and SMPM connector bodies for PCB applications.

Pre-tinned PCB-mount connectors remove cost by reducing time to install while increasing the reliability of solder joints onto the board. In addition, pre-tinned mounting surfaces help to prevent corrosion and oxidization before and after assembly.

The embossed feature under the connector body allows gases to escape when high heat is applied during the wave solder process, thus preventing the “popcorn effect."

SMP and SMPM connectors with pre-tin and “Boss” features will mate with standard cable-mounted connectors as well as with standard female-to-female adapters (commonly referred to as "bullet") which can tolerate radial and axial misalignment to provide a blind-mate interconnect solution between male connectors when stacking boards. Amphenol CIT’s SMP and SMPM connectors can also withstand multiple engagement/disengagement cycles without degradation in electrical performance. SMP and SMPM connectors are also designed to satisfy the demand for increased package density and reduced weight in microwave systems. Subminiature, lightweight, blind-mateable interconnects are ideal for complex high-performance microwave modules and systems where size and weight are primary considerations.


    • Frequency range: DC - 40 GHz (SMP) and DC - 65 GHz (SMPM)
    • 50 Ω impedance
    • Blindmate configuration
    • Interface per MIL-STD-348
    • Ability to withstand radial/axial misalignment
    • Pre-tinned legs and contacts for faster installation and increased corrosion resistance
    • Additional body feature allows heat and gas to escape, eliminating the “popcorn effect”
    • Custom connectors available
