SSMP Male PCB Solder Hermetic Connector

SSMP Male PCB Solder Hermetic Connector - High-Reliability RF Interconnect Solution 

SIPU RF Technology introduces the SSMP Male PCB Solder Hermetic Connector (Model: SIPU-SSMP-JHD5) for mission-critical applications where miniaturisation and environmental protection are essential. This connection is suitable for use from DC to 40GHz with a typical impedance of 50Ω.

Thanks to the use of superior glass-to-metal sealing technology, it achieves an outstanding leakage rate up to 10⁻³. Pa·cm³/sec guaranteeing the best hermeticity in vacuum and pressurised situations. The VSWR is ≤1.5 throughout the whole frequency range, with insertion loss negligible at ≤0.12√F(GHz)dB.

The dielectric of the connection is Glass7070 and the center and outside conductors are made of gold-plated Kovar alloy, making it operable at temperature from -65℃ to +125℃. PCB solder mount design allows for secure installation and dependable grounding. Rated for 500 mating cycles for long term reliability.

Engineering Advantages

Glass-to-Metal Hermetic Sealing

Your most demanding applications require absolute environmental isolation. The SSMP Male PCB Solder Hermetic Connector employs precision glass-to-metal sealing that creates a permanent barrier against moisture, gases, and contaminants. This sealing method ensures the connector maintains integrity in both vacuum chambers and pressurized housings.

The Kovar alloy construction matches the thermal expansion coefficient of the Glass7070 dielectric. This pairing prevents seal degradation during thermal cycling, maintaining leak-tight performance across temperature extremes.

PCB Solder-Mount Reliability

Direct PCB soldering eliminates mechanical instability common in snap-in designs. The solder interface creates a permanent electrical bond that reduces contact resistance and minimizes signal reflections. Your ground path remains consistent throughout the product lifecycle.

This mounting method supports both reflow and hand-soldering processes. The thermal properties of Kovar allow standard soldering temperatures without compromising the hermetic seal when proper technique is applied.

Miniaturized High-Frequency Performance

Space constraints in modern RF systems demand smaller interconnects without sacrificing electrical performance. The SSMP interface provides a compact footprint while maintaining 50Ω impedance control up to 40GHz.

Low insertion loss characteristics preserve signal integrity in cascaded connections. The gold-plated contact surfaces minimize intermodulation distortion and maintain stable performance over hundreds of mating cycles.

Quality Control Process

SIPU RF Technology implements rigorous inspection protocols for every production batch. Each connector undergoes dielectric withstanding voltage testing using specialized insulation testers to verify 500V ratings and insulation resistance exceeding 5,000MΩ.

Plating quality verification includes thickness measurement and adhesion testing for all gold-plated surfaces. These checks ensure consistent contact resistance and long-term reliability. Every batch receives RoHS compliance testing to meet international environmental standards.

The company's inspection process focuses on parameters guaranteed through design integrity. Voltage standing wave ratio and insertion loss specifications are verified through structural precision rather than individual unit testing for connector components.

Primary Applications

Satellite Communication Systems

Hermetically sealed electronics modules in satellites require RF feed-throughs that maintain vacuum integrity. Your payload designs benefit from connectors that prevent outgassing while supporting high-frequency signal transmission through pressure vessel walls.

Aerospace Radar Arrays

Phased array systems operating at high altitudes face extreme temperature variations and moisture exposure. The hermetic seal protects sensitive GaAs and GaN components from environmental degradation while enabling modular PCB configurations for easier maintenance.

Precision Test Equipment

Laboratory instruments requiring calibrated RF paths rely on stable, repeatable connections. The consistent electrical properties and environmental protection ensure measurement accuracy remains stable across temperature cycles and extended operational periods.

Frequently Asked Questions

Q:What frequency performance can I expect from this connector?

A:The standard SIPU-SSMP-JHD5 operates reliably from DC to 40GHz. Your specific PCB transition design influences upper frequency limits, with optimized layouts supporting performance toward 65GHz in specialized applications.

Q:How should I manage soldering thermal exposure?

A:The Kovar and Glass7070 combination tolerates standard reflow profiles. For hand-soldering, controlled pre-heating prevents thermal shock to the glass seal. Gradual temperature application protects the hermetic integrity.

Q:Is this connector compatible with GPPO interfaces?

A:Yes, the SSMP follows the same mechanical and electrical standards as GPPO series connectors. You can mate these connectors with standard GPPO components following micro-miniature push-on specifications.

Q:What environmental testing has this design passed?

A:When properly mated with gold-plated Kovar bodies, these connectors meet 48-hour and 96-hour salt spray requirements per MIL-STD-202. The hermetic seal maintains integrity in harsh marine and industrial environments.

Q:Can I use these connectors in extreme temperature applications?

A:The operating range of -65℃ to +125℃ covers most aerospace and defense requirements. The material selection ensures the hermetic seal remains effective throughout this temperature span without performance degradation.
