Solder Wire for Electronics Repair

This 63/37 tin-lead solder wire contains 1.8% flux and measures 0.8mm in diameter. The 80g spool suits circuit board work on radios, televisions, refrigerators and air conditioning units. Low melting point and good fluidity give fast soldering speed with strong adhesion. Solid joints result whether you are a beginner or have years of experience.

Upgrade from Lead-Free or Thicker Wire

Switching from lead-free alloys removes the higher melting temperatures that stress sensitive components. The 0.8mm diameter replaces thicker wire that bridges fine-pitch pads on dense boards. The jump is worth it when you need reliable flow on small joints without excessive heat. Rosin core eliminates separate flux application for quicker rework.

Capacity and Headroom for Bench Use

An 80g spool handles dozens of through-hole and surface-mount repairs before needing replacement. The 63% tin, 37% lead alloy stays fluid long enough for multi-pin IC work but solidifies quickly on power connections. It runs out on high-volume production runs or when lead-free compliance is mandatory. California Proposition 65 warning applies due to lead content.

Questions about this item

What diameter is the 63/37 solder wire and how much does the spool weigh?

The wire measures 0.8 mm (0.0315 inch) and the spool contains 80 g (0.17 lb) of alloy.

What flux percentage does the rosin-cored wire contain and is cleaning required after soldering?

Flux content is 1.8 % and the rosin core is formulated as no-wash, so residue can be left on the joint.

Does the tin-lead alloy pose any regulatory warnings I should know about before use?

Yes — the product carries a California Proposition 65 warning for lead exposure, which is linked to reproductive harm.
