In the rapidly evolving electronics industry, signal integrity and mechanical reliability are essential for modern devices. As PCBs become denser and data speeds rise, the role of high-density board-to-board connectors has never been more critical. These connectors ensure precise electrical connections, optimal signal performance, and mechanical stability, enabling engineers to design compact and high-performance systems.
KUJUN connectors, manufactured by Junhong Signal, are specifically engineered to meet these challenges. With advanced design, mold development, precision punching, automated assembly, and rigorous testing, KUJUN delivers connectors that excel in both electrical and mechanical performance.
Why High-Density Connectors Are Essential
Modern electronics require connectors that address multiple design constraints:
-
Compact PCB Layouts: Devices are increasingly miniaturized, requiring connectors that occupy minimal space without compromising performance.
-
High-Speed Data Transmission: Increasing signal frequencies demand connectors with controlled impedance and minimal crosstalk.
-
Mechanical Reliability: Frequent insertions, removals, vibrations, and thermal variations require connectors designed for long-term durability.
High-density board-to-board connectors provide precisely aligned contacts, consistent mating forces, and reliable signal paths, which are critical for ensuring stable operation in advanced electronics.
KUJUN Connector Engineering Excellence
Precision Manufacturing
KUJUN connectors are produced with high-speed precision punching machines and automated assembly lines, which allow for:
-
Micron-level pin placement: Ensures accurate alignment and reduces signal degradation.
-
Uniform contact surfaces: Guarantees low insertion resistance and consistent electrical performance.
-
Automated assembly: Minimizes human error and maintains consistent mating force and alignment.
This precision is especially important for 1.27mm and 0.8mm pin-spacing connectors, which support high-density layouts without sacrificing reliability.
Signal Integrity
High-density connectors must maintain signal integrity across multiple channels at high frequencies. KUJUN connectors achieve this through:
-
Controlled Impedance: ±10% tolerance ensures minimal reflection and consistent high-speed performance.
-
Low Crosstalk: Optimized pin layout and insulation reduce interference between adjacent signals.
-
Low Insertion Loss: Maintains high-speed signal fidelity in applications such as servers, telecom equipment, and industrial controls.
Performance Data:
Connector Type Pin Spacing Max Frequency Insertion Loss Crosstalk 1.27mm High-Speed 1.27mm 5GHz 0.3dB -45dB 0.8mm Ultra-High-Speed 0.8mm 8GHz 0.45dB -42dB CPCI2.0 1.0mm 6GHz 0.35dB -44dB The data demonstrates KUJUN connectors’ ability to maintain signal fidelity even under ultra-compact design constraints.
