Rosin core solder wire is a fundamental material used in electrical and electronics soldering. It consists of a metal alloy (typically tin and lead or lead-free alternatives) with a rosin flux core that ensures smooth, reliable, and clean solder joints. This solder wire is widely used in PCB assembly, circuit board repairs, wiring connections, and various electronic manufacturing processes.
Our rosin core wire is engineered for superior conductivity, excellent wetting properties, and minimal spattering, making it ideal for professionals and hobbyists alike. Below, we explore its features, benefits, applications, and technical specifications in detail.
1. High-Quality Alloy Composition
Our rosin wire is available in different alloy compositions to sut various requirements:
Tin-Lead (Sn-Pb) Solder (e.g., 60/40 or 63/37) – Offers excellent flow characteristics and strong joints.
Lead-Free Solder (e.g., Sn-Ag-Cu or Sn-Cu) – Compliant with RoHS and environmental regulations.
2. Rosin Flux Core for Optimal Performance
The integrated rosin flux:
Removes oxidation from metal surfaces.
Enhances solder wetting and adhesion.
Reduces soldering defects like cold joints and bridging.
Leaves minimal residue, which is non-corrosive and often self-cleaning.
3. Multiple Diameter Options
Available in various gauges (0.5mm, 0.8mm, 1.0mm, etc.) to accommodate different soldering tasks:
Thinner wires (0.3mm–0.6mm) – Ideal for precision PCB work and small components.
Thicker wires (0.8mm–1.2mm) – Suitable for larger joints and wiring connections.
4. Smooth Melting & Excellent Flow
Low melting point (183°C–227°C, depending on alloy).
Minimal spattering for clean soldering.
Forms shiny, durable solder joints.
5. Minimal Smoke & Residue
The rosin flux formulation reduces harmful fumes, ensuring a safer working environment compared to acid-core solders.
1. Printed Circuit Board (PCB) Assembly & Repair
Soldering surface-mount (SMD) and through-hole components.
Repairing broken traces or loose connections.
2. Consumer Electronics Manufacturing
Rosin core wire is used in smartphones, laptops, TVs, and other devices.
3. Automotive & Industrial Electronics
Wiring harnesses, control modules, and sensor connections.
4. DIY Electronics & Hobby Projects
Arduino, Raspberry Pi, and other prototyping applications.
5. Electrical Wiring & Cable Soldering
Rosin wire is used for joining wires, connectors, and terminals securely.

Soldering Tips for Best Results
1. Clean the Surfaces – Remove oxidation with a fiber pen or isopropyl alcohol.
2. Use the Right Temperature – 300°C–350°C for leaded solder, 350°C–400°C for lead-free.
3. Apply Flux if Needed – Extra flux may help with difficult joints.
4. Avoid Overheating – Prolonged heat can damage components.
5. Use Proper Ventilation – Even low-fume solder should be used in a well-ventilated area.
