What is Flux Rosin Core Solder?

Flux rosin core solder is a type of soldering wire that contains a flux core, which helps remove oxidation from metal surfaces and improves solder flow. The 1.6mm solder wire with a rosin core ensures clean, bubble-free joints by preventing oxidation during the soldering process.

Key Features of 1.6mm SN 60 PB 40 Solder:

• Alloy Composition: 60% Tin (Sn) and 40% Lead (Pb) – a perfect balance for strong, ductile solder joints.

• Flux Core: Contains rosin flux, which cleans surfaces and enhances wetting for better adhesion.

• Diameter: 1.6mm solder thickness is ideal for medium to large soldering tasks, offering good control and solder deposition.

• Weight: Available in a convenient 1lb solder spool, suitable for both professional and DIY use.

• Melting Point: Around 183°C (361°F), making it easy to work with standard soldering irons.

Why Choose SN 60 PB 40 Lead Core Solder?

The Sn 60 Pb 40 solder alloy is widely used in electronics due to its excellent properties:

1. Superior Electrical Conductivity

• The lead core solder ensures low electrical resistance, making it ideal for PCB circuits and sensitive electronic components.

2. Excellent Thermal Conductivity

• The alloy efficiently transfers heat, allowing for quick and smooth soldering without damaging components.

3. Strong and Durable Joints

• The 60/40 tin-lead ratio provides a eutectic mixture, meaning it solidifies quickly with minimal shrinkage, reducing cold solder joints.

4. Easy to Work With

• The 1.6mm solder diameter offers precision for PCB work, while the flux rosin core eliminates the need for additional flux application.

Applications of 1.6mm Flux Rosin Core Solder

This lead core solder is versatile and suitable for various applications, including:

1. PCB Assembly & Repair

• Perfect for soldering through-hole components, wires, and surface-mount devices (SMDs) on circuit boards.

2. Electrical Wiring & Connectors

• Used in automotive, appliance, and industrial wiring due to its strong bonding capability.

3. DIY Electronics & Hobby Projects

• A favorite among hobbyists for its ease of use and reliable performance in prototyping and repairs.

4. Maintenance & Rework

• The rosin flux core helps in desoldering and reworking old or damaged connections.

Advantages of Using Rosin Core Solder

Compared to other flux types, flux rosin core solder offers several benefits:

1. Self-Cleaning Action

• The rosin core removes oxidation and impurities, ensuring a clean soldering surface.

2. No Residue Buildup

• Unlike acid-core flux, rosin flux is non-corrosive and safe for electronics.

3. Improved Solder Flow

• The 1.6mm solder wire melts evenly, reducing the risk of dry or weak joints.

4. Cost-Effective & Efficient

• A 1lb solder spool lasts long, making it a cost-effective solution for frequent soldering tasks.

How to Use 1.6mm SN 60 PB 40 Solder Wire

To achieve the best results with this Sn 60 Pb 40 solder, follow these steps:

1. Prepare the Soldering Iron

• Set the temperature between 300°C – 350°C (572°F – 662°F) for optimal performance.

2. Clean the Surfaces

• Ensure the PCB or metal parts are free from dirt and oxidation before soldering.

3. Apply the Solder

• Touch the 1.6mm solder wire to the joint while heating it with the soldering iron. The flux rosin core will activate and improve adhesion.

4. Inspect the Joint

• A good solder joint should be shiny and smooth, without cracks or dull spots.

Safety Considerations When Using Lead Core Solder

While lead core solder provides excellent performance, proper handling is essential:

• Work in a Well-Ventilated Area – Lead fumes can be harmful if inhaled.

• Wash Hands After Use – Prevents lead contamination.

• Use Lead-Free Alternatives for Food-Related Applications – Sn 60 Pb 40 solder is not suitable for plumbing or food-grade soldering.
