Weller Lead Free Solder, 0.5mm Wire Diameter, 100g Product Weight - T0051388299
This lead-free solder is a rosin-flux cored wire designed for soldering tasks in electronics and related industrial settings. It supplies a low-impurity alloy suited to hand and machine soldering processes where lead-free materials are required. The wire form and fine diameter support precision work across various assembly and repair contexts.
Features and Benefits:
• 96.5% tin composition provides predictable wetting and joint formation
• 3% silver content increases mechanical strength of joints
• 0.5% copper reduces brittle intermetallic growth during service
• 0.5mm wire diameter enables fine-pitch soldering accuracy
• 217°C melting point supports consistent reflow and soldering profiles
• 100g spool format offers convenient handling for frequent use
• 3% silver content increases mechanical strength of joints
• 0.5% copper reduces brittle intermetallic growth during service
• 0.5mm wire diameter enables fine-pitch soldering accuracy
• 217°C melting point supports consistent reflow and soldering profiles
• 100g spool format offers convenient handling for frequent use
Applications
• Suitable for soldering electronic components on dense assemblies
• Ideal for precision rework of surface-mount devices
• Used with wave or selective soldering equipment in small batches
• Can be used for connector and cable terminations requiring lead-free alloys

How does the flux type influence residue and cleaning requirements?
The rosin-based flux provides Active soldering performance with residues that are typically mildly tacky and may require solvent cleaning in sensitive circuits.
What thermal behaviour should I expect during soldering cycles?
The alloy transitions at 217°C, permitting standard lead-free soldering temperatures with controlled heat application to avoid thermal stress.
How does the silver content affect joint fatigue resistance?
The 3% silver fraction increases tensile and shear strength of joints, improving cyclic load endurance compared with tin-only alloys.
Is the wire suitable for both manual and automated processes?
The wire form and 0.5mm diameter make it appropriate for hand soldering and for feeding in automated dispensers or soldering heads.
