0.8mm Sn38Pb62 Solder Wire – 38% Tin (Sn) – 100gm/reel, 400gm/reel, 800gm/reel for THT Soldering

When it comes to Through-Hole Technology (THT) soldering, choosing the right solder wire is crucial for achieving strong, reliable connections. One of the most trusted options in the electronics industry is 0.8mm Sn38Pb62 solder wire, which contains 38% tin (Sn) and 62% lead (Pb). This alloy offers excellent wetting properties, smooth flow, and strong joints, making it ideal for both professional and hobbyist applications.

In this article, we’ll explore the features, benefits, and applications of solder wire Sn38Pb62, along with the different reel sizes available—100gm/reel, 400gm/reel, and 800gm/reel. Whether you're working on PCB assembly, repairs, or DIY projects, understanding the advantages of solder wire Sn38 will help you achieve optimal results.

Why Choose 0.8mm Sn38Pb62 Solder Wire?

1. Optimal Composition for THT Soldering

The solder wire 38% Sn composition ensures a balanced melting point and excellent electrical conductivity. The 38% tin (Sn) content provides good wetting action, while the 62% lead (Pb) enhances durability and reduces the risk of cold solder joints.

Compared to lead-free alternatives, solder wire Sn38Pb62 flows smoothly at lower temperatures, minimizing thermal stress on sensitive components. This makes it a preferred choice for THT soldering, where precision and reliability are key.

2. 0.8mm Diameter – Perfect for Precision Work

The 0.8mm solder wire Sn38 is an excellent choice for medium-sized solder joints. Its thickness is ideal for:

• Through-hole component soldering

• PCB repairs and rework

• Hand soldering with precision tips

For those who need different quantities, solder wire Sn38 100gm/reel is great for small projects, while solder wire Sn38 400gm/reel and solder wire Sn38 800gm/reel are better suited for frequent use in workshops.

Key Features of Sn38Pb62 Solder Wire

1. Excellent Wetting & Flow Characteristics

The solder wire 38% tin formulation ensures superior wetting, allowing the solder to spread evenly across joints. This results in strong, shiny, and void-free connections—essential for long-lasting electronic assemblies.

2. Reliable Mechanical Strength

Unlike some lead-free solders that can be brittle, solder wire Sn38Pb62 provides excellent mechanical strength. This is particularly important in applications where vibrations or mechanical stress may occur.

3. Wide Range of Reel Sizes

To suit different needs, this solder wire is available in multiple sizes:

• Solder wire Sn38 100gm/reel – Ideal for hobbyists and occasional use

• Solder wire Sn38 400gm/reel – Great for small to medium production runs

• Solder wire Sn38 800gm/reel – Best for professional workshops and high-volume soldering

For those who prefer a mid-sized option, 250g solder wire alternatives may also be available from select suppliers.

Applications of 0.8mm Sn38 Solder Wire

1. Through-Hole Technology (THT) Assembly

The solder wire for THT applications is widely used in:

• Consumer electronics manufacturing

• Automotive PCB assemblies

• Industrial control systems

Its 0.8mm diameter ensures precise application without excessive solder buildup.

2. Repair and Rework

Whether fixing a broken trace or replacing a through-hole component, solder wire Sn38 0.8mm provides the right balance of control and flow.

3. DIY Electronics & Prototyping

Hobbyists and engineers alike benefit from the ease of use of solder wire 38% Sn, especially when working on breadboards or custom circuits.

Choosing the Right Reel Size

1. Solder Wire Sn38 100gm/reel – For Occasional Use

Perfect for:

• Small repairs

• Beginners learning soldering

• Low-volume projects

2. Solder Wire Sn38 400gm/reel – For Regular Use

Best for:

• Medium-scale PCB assembly

• Repair shops

• Educational labs

3. Solder Wire Sn38 800gm/reel – For High-Volume Work

Ideal for:

• Professional electronics manufacturing

• Large-scale repairs

• Industrial applications

For those who need flexibility, a 250g solder wire option may also be a practical choice.

Conclusion

The 0.8mm Sn38Pb62 solder wire with 38% tin (Sn) is a top choice for THT soldering due to its excellent flow, strong joints, and ease of use. Whether you need a 100gm/reel for small projects or an 800gm/reel for industrial use, this solder wire ensures reliable performance.

By selecting the right solder wire Sn38, you can enhance your soldering efficiency and achieve durable, high-quality connections in all your electronic projects.
