I. Product Overview

II. Product Characteristics

(I) Material Structure

1. Steel Core Providing Strength
   With steel as the core, the wire gains mechanical strength and can withstand external forces during PCB-related operations, preventing breakage and maintaining circuit stability. For example, in PCB applications that are subject to external forces, the steel core can keep the jumper wire intact.
2. Copper Layer Ensuring Conductivity
   There is a uniform high-purity copper layer outside the steel core, which ensures good electrical conductivity, reduces power and signal losses, and also takes cost into account. For instance, in PCB lines for high-speed data transmission, the copper layer helps signals transmit quickly.
3. Tin Layer for Protection
   The surface is treated with hot-dip galvanizing tin coating, which enhances solderability and is beneficial for welding. It can also resist corrosion, protect the copper layer and the steel core, and extend the product's service life. In electronic equipment used in harsh environments, the tin coating maintains the performance of the jumper wire.

(II) Physical Characteristics

1. Flexible and Applicable Wire Diameter
   The wire diameter ranges from 0.08 to 0.3mm, meeting different PCB design requirements. In precision multi-layer PCBs, the 0.08mm thin wire is used for tiny connections, while the 0.3mm wire is suitable for circuits with large current or high strength requirements. Just like the motherboard of a regular phone requires the cooperation of multiple wire diameters.
2. Combination of Toughness and Flexibility
   Although it contains a steel core, through manufacturing processes, it is both tough and flexible. During PCB processing, it is not easily damaged when facing operations like bending, ensuring the integrity of the circuit. It also facilitates automated production, improving efficiency and quality. For example, in the manufacturing of flexible PCB boards, it can bend with the board without affecting electrical performance.
3. Excellent Surface Quality
   The hot-dip galvanizing tin coating makes the wire surface smooth and flawless, which is conducive to welding and facilitates compact wiring on PCBs, enhancing overall performance and reliability. In high-end PCB designs, the high-quality surface of the jumper wire ensures signal stability and reduces electromagnetic interference.

(III) Electrical Characteristics

1. Low Resistance for High Efficiency and Energy Saving
   The copper layer makes the wire have a low resistance. When current passes through, the power loss is small, reducing heat generation of PCBs, improving energy utilization and operation stability. In high-frequency circuits, it can suppress signal problems and meet the requirements of high-speed transmission. For example, in the high-speed lines of computer motherboards and the radio frequency circuits of communication equipment, the wire with low resistance ensures signal quality.
2. Stable and Reliable Performance
   The electrical performance remains stable under normal temperature or within a certain temperature change range. Parameters such as resistance are not significantly affected by the external environment, laying a solid foundation for the long-term stable operation of electronic equipment. In industrial automation equipment, it can work stably even in harsh environments, ensuring the precise operation of the control system.

III. Application Advantages of the Product

   The comprehensive performance makes PCB jumper wire connections reliable, enabling them to resist various environmental factors and prevent circuit failures. It is extremely important in medical, aerospace and other equipment with high reliability requirements, reducing the failure rate and improving the safety and stability of the system. For example, in aerospace electronic equipment, it works stably for a long time under extreme environments, which is related to flight safety.
2. Helping with High-Density Layout
   The precise wire diameter and good flexibility support high-density wiring on PCBs. With the development of electronic products, PCB designs are becoming more complex. It can arrange multiple components and circuits in a limited space, broadening the design space. For example, in the design of PCBs for portable devices such as regular phones, high-density wiring and the integration of functional modules are achieved with its help.
3. Good Compatibility and Adaptability
   It has good compatibility with mainstream PCB manufacturing processes and electronic components. Whether it is traditional or modern manufacturing processes, it can match well, and it also has good compatibility with the welding processes of various components, facilitating circuit design and assembly and improving production flexibility and efficiency. For example, in the manufacturing of computer motherboards, when multiple processes coexist, it can work stably and cooperate with components.

(II) Advantages in Improving the Performance of Electronic Equipment

1. Ensuring Signal Accuracy
   In high-speed digital and high-frequency analog circuits, its low resistance, low inductance and stable electrical performance reduce signal transmission problems and ensure the accurate and complete transmission of signals, which has a significant effect on improving the communication, data processing and image display performance of electronic equipment. For example, in the design of computer graphics cards, it ensures the accurate transmission of graphic data and presents clear images. In high-speed network equipment, it ensures the stable exchange of data and improves network performance.
