SMB M BH PCB MOUNT SOLDER

Description

The SMB Male Bulkhead PCB Mount Connector is a dual-purpose RF interface that combines the stability of a chassis-mount bulkhead with the direct integration of a PCB solder tail. This connector is engineered to be mounted through an equipment enclosure wall while simultaneously soldering directly onto a mother-board or daughter-card. The “Bulkhead” design includes a threaded outer body, hex nut, and lock washer, creating a rigid mechanical ground and vibration-resistant installation that protects the delicate PCB solder joints from external cable torque.

Designed for performance from DC up to 4 GHz, the SMB male (plug) interface utilizes a professional snap-on coupling mechanism. This allows for rapid, tool-free mating with any standard SMB female jack, making it ideal for high-density electronic assemblies where space for traditional threaded connectors is limited. Manufactured with a high-grade gold-plated brass body and premium PTFE (Teflon) insulation, this connector ensures minimal signal attenuation and superior protection against oxidation. The straight solder-leg configuration is optimized for standard PCB thicknesses, providing a low-inductance path for critical RF signals.

Key Technical Advantages

• Integrated Chassis-to-Board Solution: Eliminates the need for internal jumper cables by allowing the PCB to interface directly with the enclosure wall, reducing signal loss and assembly costs.

• Mechanical Strain Relief: The bulkhead mounting hardware absorbs mechanical stress from external cable mating, preventing damage to the PCB traces and solder pads.

• High-Density Port Capability: The subminiature SMB footprint allows for multiple connectors to be mounted in close proximity on a single panel, ideal for MIMO and multi-channel systems.

• Rapid Snap-On Efficiency: Facilitates fast equipment assembly and field maintenance with a secure “click-lock” mechanism that is inherently resistant to vibration.

• Superior Thermal Stability: Features a high-grade PTFE dielectric and gold-plated contacts that withstand wave and hand soldering temperatures without compromising electrical performance.
