Cross PIN, Made of Copper with Gold Plating The cross PIN is one of the simplest types of PINs. It is commonly used for PCB solder terminal positioning and provides connections between electronic devices, enabling the transmission of electrical signals and power signals between circuit boards. Cross PINs are designed to offer reliable connection performance, capable of handling specific levels of current and voltage, ensuring stable connections and proper operation of devices. In electronic device manufacturing, the cross PIN is a widely used type of connector. FULLERKREG Precision offers significant production advantages, high-quality control standards, and competitive cost benefits. |

Knurled Pin The knurled pin is a common type of connector pin, designed with a textured surface to improve grip and facilitate easier handling during installation. Pins and inserts play a critical role in the design and functionality of electronic devices. Their high level of standardization and wide availability make the design, manufacturing, and maintenance of electronic equipment more efficient and convenient. As technology continues to advance, the design of connectors evolves to meet increasing performance demands and diverse application requirements. |

Pins and Cross-Shaped Copper Pins Pins and sockets used in connectors are essential components in electronic engineering. They play a critical role in transmitting current or signals on printed circuit boards (PCBs) or between devices. The design of pins (male connectors) and sockets (female connectors) aims to ensure that electronic devices can be connected and disconnected safely, reliably, and conveniently. Pins typically refer to protruding conductive components that can be inserted into a corresponding part, while sockets are the complementary parts designed to receive the pins. This design allows for tight, reversible connections between electronic devices or their components, enabling multiple connections and disconnections without damaging the equipment. |

Materials and Surface Treatments for Connector Pins (PINs)
Connector pins and pin cores are typically machined from copper rods or elastic copper rods with excellent electrical conductivity. To achieve low contact resistance and corrosion resistance, the surface is treated with gold plating, silver plating, or tin plating.
Commonly Used Materials:
Brass and Copper Alloys:
C3604, C3602, H59, Hpb59-1, Hpb59-3, H62, H65, H68, H70, H80
Phosphor Bronze and Other Copper Alloys:
C5400, C2700, C2680, C5210, C5191, C51000, QBe2.0, C1100
The raw materials are commonly supplied as 2.5-meter-long rods for machining.
Material Characteristics:
H59 Series and C3604:
Cost-effective options with high strength and hardness.
Excellent plasticity, even under high-temperature conditions, allowing for effective pressure processing.
Moderate corrosion resistance, making them ideal for pin manufacturing.
H62 Brass:
Average copper content: 62%.
Good mechanical properties with excellent plasticity in hot conditions and adequate plasticity in cold conditions.
Easy to machine and weld, suitable for applications requiring higher loads (compared to H59 series and C3604).
Similarly, H65, H68, H70, and other high-copper-content alloys can also be used for pin and socket components.
C54400 Phosphor Bronze (with Lead):
Good machinability and cold workability.
Easy to weld and braze.
Often used for manufacturing pins and sockets.
C2700, C2680, C1100, and Similar Materials:
These materials exhibit similar properties and are also commonly used for pin and socket manufacturing.
Surface Plating for Pins (PINs)
The plating on connector pins not only enhances their durability and wear resistance but also helps establish and maintain stable impedance from an electrical performance perspective. Common plating options include:
Tin Plating:
Typically applied as a tin layer over a nickel base. Tin-plated pins exhibit excellent solderability and conductivity.
Gold Plating:
Leveraging gold's superior conductivity, gold plating reduces resistance and improves electrical performance. Additionally, it provides a premium and attractive appearance.
Silver Plating:
Similar to gold plating, silver plating offers excellent conductivity while maintaining a balance of cost and performance.
Nickel Plating:
Due to its lower cost, nickel plating is also widely used for pin and socket components.
