Two small silver spools of 0.8mm solder wire in clear tubes

SEQURE

SEQURE Rosin Core Solder 0.8mm 20g 2PCS

SKU CH-P8KP-GX9GF

Lead-free rosin-core solder wire in 0.8 mm diameter, supplied as two 12 g tubes for electronics work

  • Product typeRosin Core
  • Lead-free alloy of 99% tin with silver and copper
  • 8 mm diameter melts cleanly at 215–220 °C
  • Rosin core removes the need for separate flux
  • Two 12 g tubes in a compact portable case
  • Suitable for circuit-board repair and general electrical work

Solder wire for electronics repair

This lead-free solder wire contains 99% tin with 0.3% silver and 0.7% copper. Each spool weighs 12g and measures 0.8mm in diameter. The built-in rosin core removes the need for separate flux during electrical work. Two portable tubes are included for convenient storage and transport.

Suited for circuit boards and DIY projects

Hobbyists repairing TV boards or working on home electrical tasks will find the moderate flux and clean flow practical. The low melting point between 215°C and 220°C helps prevent component damage. Users needing larger diameters or high-volume production spools should consider alternative formats.

Two 12g spools for intermittent use

The combined 20g supply handles occasional repairs and small prototype builds comfortably. Neat winding prevents knots during repeated sessions. Heavy assembly jobs or daily professional use will exhaust the small spools quickly, requiring frequent replacement.

Questions about this item

What soldering iron temperature range is needed for the 215°C – 220°C melting point?

Set your iron between 215°C and 220°C (419°F – 428°F) so the 99% Sn, 0.3% Ag, 0.7% Cu alloy melts cleanly without overheating the joint.

Will the 0.8mm diameter work on fine-pitch surface-mount pads I already repair?

The 0.8mm wire feeds precisely into tight SMD pads, and the built-in rosin core flows evenly without extra flux, making rework on existing boards straightforward.

How can I confirm the rosin core is active after the first joint?

A shiny, concave fillet with no visible flux residue or splatter shows the core flux has wetted the 99% Sn alloy properly.
