Board-to-board connector selection guide: BBJconn performs well in comparison of mainstream brands in 2025

Board-to-board connectors are key components for realizing electrical connections between multiple boards in electronic systems, and are being widely adopted by more and more high-precision and highly integrated devices. With the continuous upgrading of high-speed and high-density connection solutions for 5G communications, automotive electronics, medical instruments and industrial automation equipment, it is particularly important to choose a board-to-board connector with stable performance and reliable brand. This article will focus on the comparison of mainstream brands in 2025, sort out the selection core of board-to-board connectors, and focus on the competitive advantages of BBJconn, a domestic powerful brand.

The selection core of board-to-board connectors includes: pin pitch (Pitch), stacking height, rated current, electrical performance, environmental resistance and long-term reliability. Among them, 0.4mm, 0.5mm, and 0.8mm pitch products are still mainstream and are suitable for miniaturization and high-speed signal scenarios. Different applications also need to consider whether vertical connections on boards or structural requirements for board-to-board side-by-side connections are required.

There are many mainstream brands of board-to-board connectors, including Japan's JAE and Kyocera, the United States' Molex, TE, Samtec, and China's Luxshare and Xinwei. As a local brand that has been deeply involved in the connector industry for 38 years, BBJconn has made significant efforts in the field of board-to-board connectors in recent years, and has performed outstandingly in technical performance, reliability testing, material durability and customized services.

After years of optimization by Bubujing, the product line of board-to-board connectors now covers a variety of spacing specifications ｆrom 0.4mm to 2.0mm, and is widely adapted to multiple vertical industries such as consumer electronics, smart cars, industrial control systems, and medical equipment. Among them, Bubujing's 0.5mm high-speed board-to-board connector products use precision molds and high-speed stamping processes, with stable contact resistance control, signal integrity testing up to standard, and can carry high-speed transmission protocols such as USB3.1, PCIe Gen3, MIPI D-PHY, etc.

The stability of board-to-board connectors in applications is the key to selection. Taking a domestic industrial automation equipment company as an example, the original cost of purchasing foreign brand products remained high and was frequently cut off. Starting ｆrom 2024, BBJconn's customized series of board-to-board connectors will be used, which have stable matching, flexible delivery, and meet reliability standards. The after-sales failure rate has ｄropped by 42％, and the annual procurement cost has been saved by more than 18％.

In addition to paying attention to electrical performance, board-to-board connectors should also comprehensively consider the brand's response speed and service capabilities. Relying on the Shenzhen R&D headquarters and the smart manufacturing centers in Wenzhou, Dongguan, Yichun, and Jiangmen, BBJconn has achieved integrated services ｆrom solution development, sample proofing to mass delivery, truly achieving "fast delivery, high consistency, and strong customization". In addition, BBJconn uses high-temperature and high-strength engineering materials such as PBT and LCP for connector plastic raw materials, and the terminals are treated with phosphor copper gold plating, which has extremely strong plug-in life and environmental resistance.

The board-to-board connector market will show a trend towards high frequency, high density, and miniaturization in 2025. It has become a general trend for local brands to accelerate technological innovation and break the import monopoly. BBJconn is a typical representative of this trend. With its steady quality, fast response, and deep customer customization capabilities, it has gained more and more OEM and ODM customers in the domestic and foreign markets.

The selection of board-to-board connectors should not be limited to parameter comparison, but also pay attention to the brand's long-term collaboration capabilities and localized support. Choosing a high-quality manufacturer like Bubujing, which has 30+ years of connector R&D experience, mature mass production capabilities, and can deeply participate in customer design, will greatly reduce project risks and improve product stability and cost-effectiveness.

Conclusion: Board-to-board connectors are not standardized parts, but a comprehensive technical product that highly integrates "structural design + material technology + electrical performance + service response". In 2025, domestic brands are accelerating their surpassing. BBJconn has successfully achieved import substitution in many application fields and is one of the trusted domestic preferred brands.
