Key Features & Benefits of SMD Soldering Lead with Flux (Sn60/Pb40)

1. Superior Sn60/Pb40 Alloy Composition

Eutectic-like properties for smooth melting at 183-190°C (361-374°F) 

Excellent thermal conductivity ensures fast heat transfer 

Strong, durable joints with superior mechanical strength 

Reduced risk of cold solder joints compared to lead-free alternatives

 

2. Precision 1.0mm Diameter with Flux Core

Optimal size for controlled application in SMD work

 

Rosin-based flux core (1.8-2.2% content) for:

Effective oxide removal

Enhanced wetting and flow

Reduced solder balling and splashing

Low-residue formulation minimizes post-soldering cleaning

 

3. SMD Soldering Lead with Flux (Sn60/Pb40) is Optimized for SMD Applications

1. Excellent for fine-pitch components (0603, 0805, SOT, QFP packages)

2. Prevents bridging in high-density PCB layouts

3. Controlled solder deposition for rework and repair
