Small-Volume and High-Density Board Layout Connection Solution

     

      In the fields of communications, testing, aerospace, and others, the demand for equipment miniaturization and high performance efficiency is increasingly prominent. Small-volume and high-density board layout connections have become a key technical support. The GPPO (MINI-SMP) series connectors, with their unique design and excellent performance, provide an ideal solution for such scenarios.

Core of the Solution: Advantages of GPPO Series Connectors

    The GPPO series connectors are designed with the core concepts of "miniaturization" and "high-density adaptation", and their performance and structural characteristics perfectly meet the needs of modern board layout:

1. Small Volume, Adaptable to High-Density Board Layout

As MINI-SMP  connectors, the GPPO series are small in size, enabling more connection points to be laid out in limited PCB space, which is particularly suitable for high-density board layout scenarios. Whether it is the interconnection between the main board and sub-card of communication modules or the integration of multiple modules in complex systems, they can effectively save space and improve board layout efficiency.

 

2. Excellent High-Frequency Performance, Supporting High-Speed Transmission

This series of connectors perform excellently in the high-frequency field:

 

GPPO-JHD1 supports the frequency range from DC to 40GHz, and GPPO-KK can even cover from DC to 65GHz, meeting the high-speed data transmission requirements of 10Gbps or 40Gbps, and adapting to the transmission requirements of high-frequency signals in modern communication and testing systems.

The electrical performance is stable, with an impedance of 50 ohms, ensuring the matching of signal transmission; the insertion loss is ≤0.1×√(f_GHz), and the return loss reaches 13dB at 40GHz (GPPO-JHD1) and 15dB at 50GHz (GPPO-KK), effectively reducing signal attenuation and reflection, and ensuring transmission quality.

 

3. Efficient Connection Design, Improving Operational Convenience

The GPPO series adopts a Push/Snap structure, supporting blind mating operation, which can complete the connection without tools, greatly improving assembly efficiency. This design is particularly suitable for scenarios with limited space and high difficulty in manual operation, and also reduces the risk of connection failures caused by improper operation.

In addition, some models (such as GPPO-JHD1) support tape and reel mounting, which can be adapted to automated mass production processes, further meeting the efficiency requirements of large-scale production.

 

4. Flexible Adaptation, Compatible with Multi-Scenario Requirements

Supports Bullet (connecting pins) of different lengths, which can absorb axial and radial offsets, adapting to possible installation errors in board-to-board connections, and ensuring connection stability. For example, when the board-to-board distance is ≥7.94mm, reliable connection can be achieved through customized Bullet (length ≥5.36mm).

Provides a variety of interface types: GPPO-JHD1 is a male header for PCB, and GPPO-KK is a female-female adapter, meeting different connection combination requirements and improving the flexibility of the solution.

 

5. Reliable and Durable, Adapting to Severe Environments

In terms of material selection, the center contact, outer contact, and body are all gold-plated (beryllium copper or brass), ensuring excellent conductivity and corrosion resistance; the dielectric materials are PEEK or PTFE, which are high-temperature resistant and have excellent insulation performance.

In terms of environmental adaptability, the products can work stably in a wide temperature range of -40°C to 155°C (GPPO-JHD1) or -55°C to 165°C (GPPO-KK), and meet the RoHS environmental protection standards, suitable for harsh environments such as aerospace and military industry.

 

Typical Application Scenarios

The characteristics of GPPO series connectors make them play an important role in multiple fields:

Communication Module Interconnection: High-speed signal transmission between the main board and sub-card, adapting to the high-density board layout requirements of 5G, data centers and other scenarios.

High-Speed Testing Modules: Used in high-frequency testing scenarios such as S-parameter measurement to ensure accurate transmission of test signals.

Aerospace/Military Systems: Provide stable board-to-board connections for high-speed board design at the system level in harsh temperature and humidity environments, ensuring reliable operation of equipment.

 

Summary

The GPPO series connectors, with the advantages of small volume, high density, excellent high-frequency performance, efficient connection, and strong environmental adaptability, have become an ideal solution for modern board layout connections. Whether it is the miniaturization design of civil communication equipment or the high reliability requirements of military systems, they can provide stable and efficient connection support, promoting the further development of related fields.
