Board to Board connections

Product catalog summary

Overview: The document provides comprehensive information on HUBER+SUHNER's MBX, MFBX, and MMBX connectors, which are designed for RF interconnections between boards and modules. These connectors are noted for their mechanical design that accommodates misalignment while maintaining excellent electrical performance, supporting higher integration and miniaturization.

Key Benefits:

Cost Efficiency: Direct board-to-board connections reduce costs compared to cable connections and allow for larger tolerances.
Miniaturization: Offers the smallest board-to-board distance in its class, enabling compact designs.
Reliability: Automated production ensures high quality and flexibility, with high output power and excellent RF performance.
Secure Mating: Features blind mateability for fast module assembly.

Product Family:

MBX: High axial float, high output power, excellent return loss, smallest board-to-board distances.
MBX 2nd Generation: Similar to MBX with cost-effective solutions.
MFBX: Medium float, low cost, good shielding, small distances.
MMBX: High frequencies, good return loss, smallest distances.

Technical Specifications:

Frequency Range: MBX and MBX 2nd (DC to 6 GHz), MFBX (DC to 3.5 GHz), MMBX (DC to 12.4 GHz).
Axial and Radial Float: Varies by model, with MBX offering the highest axial float.
Power Handling: Up to 260 W at 2.4 GHz for MBX.
Environmental Resistance: Operates in temperatures from -55 to +155 °C, with resistance to thermal shock, moisture, vibration, and corrosion.

Applications: Suitable for various configurations including board-to-board, panel-to-panel, and board-to-panel connections, with right-angle and through-panel options.

Design Guidelines: Recommendations include using guiding pins and distance holders for alignment and maintaining misalignment within working ranges. Detailed mechanical dimensions and 3D STEP files are available for design integration.

Electrical and Mechanical Data: Detailed specifications for impedance, voltage, insulation resistance, contact resistance, return loss, and mechanical durability are provided for different connector types.

Material and Plating: Connectors are made from materials like brass, bronze, and copper-beryllium alloy, with SUCOPRO® gold plating for enhanced performance.

Packaging and Assembly: Connectors are available in various packaging options including single, bulk, and tape and reel, with specific assembly instructions provided.

Durability: 50 to 500 matings depending on the series
Axial and Radial Float: ± 0.8 mm for MBX/MFBX, ± 0.3 mm axial and variable radial for MMBX

Environmental Data:

Temperature Range: −55 to +155 °C / −67 to +311 °F
Test Conditions: Includes high temperature endurance, rapid temperature change, damp heat steady state, vibration, and mechanical shock tests

Design Guidelines:

Ensure alignment within specified axial and radial working ranges for effective mating.
Use guiding pins and distance holders to maintain alignment and minimize misalignment.
Blind mateability is dependent on maintaining specified connecting ranges and funnel sizes.

Recommendations: HUBER+SUHNER recommends using guiding pins for alignment and provides 3D STEP files for design integration. For specific applications or environmental conditions not covered by standard tests, additional requirements should be requested.

Specifications:

PCB Connectors: Includes straight PCB jacks (female) and plugs (male) with surface mount (SMT) and through-hole (THT) types. Pull-in ranges vary from 0.65 mm to 1.80 mm.
Adaptors: Straight adaptors for plug-to-plug connections with varying board-to-board distances and pull-in ranges. Custom lengths available upon request.
Test Boards: MMBX test board for measuring return loss and insertion loss with SMA connectors. Reference board available for insertion loss measurements.
Cable Connectors: Includes straight and right-angle cable plugs with specific assembly instructions and crimp inserts.

Procedures:

Assembly and Disassembly Tools: Tools for MMBX to SMA interface connections are listed with item numbers and packaging details.

Standards and Certifications: HUBER+SUHNER is certified according to EN(AS) 9100, ISO 9001, ISO 14001, ISO/TS 16949, and IRIS.

Benefits Lower cost Direct board-to-board connections with compensating misalignment (axial float ± 1.2 mm) do not only save costs compared to cable connections but rather allow larger tolerances on all other parts. Minituarization HUBER+SUHNER board-to-board connectors provide the smallest board-to-board distance (6.7 mm) in class. This enables smaller designs with less weight and provide much more space on the PCB boards This opens new possibilities for module designs without active cooling. Thanks to the unique ball joint design the connectors provide excellent return loss values over the...

Series MBX – design guideline Working range (axial and radial) In mated condition, the two PCB connector have to be aligned within the dimension given for the axial and radial working range. HUBER+SUHNER recommends using guiding pins to align the boards within the connecting range and working range. Distance holders to maintain the axial misalignment within working range are also of benefit. The axial working range is ± 1.2 mm, the radial working range is ± 1.0 mm. In contradiction to the MMBX interface, the tilt of the adaptor is limited with MBX. The great advantage of this feature is that...
