Description
The Proskit 8PK-033K is a rosin-core solder wire with a 63% tin and 37% lead composition, offered in a 1.0mm diameter and a 250g spool. Its non-corrosive formulation protects circuit board pads and component leads from damage during the soldering process.
The 63/37 alloy is a eutectic composition, meaning it transitions directly from solid to liquid at a single melting point, making it straightforward to work with for both hobbyist and professional soldering tasks.
Key Features
- 63% tin, 37% lead alloy composition
- Diameter: ø1.0mm
- Weight: 250gr spool
- Non-corrosive formulation
- Strong adhesion to solder joints
Product Benefits
- The 63/37 eutectic alloy transitions sharply between solid and liquid states, reducing cold joint risk compared to non-eutectic alloys
- Non-corrosive flux protects PCB pads and component legs from chemical damage during and after soldering
- Strong adhesion forms reliable solder joints that hold under mechanical stress
- The 1.0mm diameter suits a broad range of through-hole and general soldering work without being too thick for smaller joints
- The 250g spool provides ample supply for extended repair or assembly projects

Why You'll Love It
- The 63/37 eutectic formula is one of the most widely recommended alloys for electronics repair — it flows reliably and solidifies cleanly
- The 1.0mm diameter is versatile enough for most through-hole work while still being manageable for medium SMD joints
- The 250g spool reduces how often you need to reorder, keeping your workbench supplied for longer projects
- Non-corrosive flux means you can leave the joints without immediate cleanup and still have a clean, reliable result
