The 1.0mm 100g Solder Wire is a professional-grade solder designed for general electronics assembly, PCB repair, and through-hole component soldering . With a diameter of 1.0mm (0.039 inches), this solder wire offers a balanced feeding rate suitable for most applications, from connector terminals to larger PCB pads . It is available in leaded and lead-free variants, with lead-free (tin‑copper or tin‑silver‑copper) formulations meeting RoHS environmental standards.

This weight provides ample material for regular use while remaining easy to handle and store. The rosin flux core ensures good wetting and reliable joints, making it ideal for both professional technicians and hobbyists .

Key Features

1. 1.0mm Diameter (0.039")
The 1.0mm gauge offers a versatile balance – thick enough for through-hole components and connectors, yet fine enough for general PCB assembly without excessive solder deposition .

2. Rosin or No-Clean Flux Core
Contains a built‑in flux core (typically 2‑3.5% flux content) that cleans oxidation during soldering, improves solder flow, and leaves minimal non‑corrosive residue for reliable, bright joints . The flux also reduces spatter, keeping the work area clean .
