Hiflo Soldering Wire

Hiflo Soldering Wire – High-Purity Rosin-Activated Core Wire for Electronics Assembly

The Hiflo Soldering Wire is an industry-grade, rosin-activated cored solder wire engineered by Hiflo Solders for precision electrical repairs, PCB assembly, and industrial manufacturing. Manufactured using high-purity virgin tin and lead alloys subjected to dross-lowering treatments, Hiflo Soldering Wire provides rapid thermal transfer, superior wetting action, and consistent mechanical joints.

As displayed on the product spool label, this variant features a 60/40 tin-to-lead ratio (Sn60/Pb40) with a 1.6 mm wire diameter and an integrated 2.2% Rosin Activated (RA) flux core. The integrated RA flux removes surface oxides automatically as heat is applied, eliminating the need for separate external flux application during hand soldering or circuit board rework. Packaged on a compact spool (available in 100 g, 200 g, and 500 g sizes), it is an essential consumable for electrical technicians and assembly lines.

Key Features of Hiflo Soldering Wire

• 60/40 Tin-Lead Composition: Blends 60% tin and 40% lead to deliver a low melting range (183°C to 190°C), enabling fast melting and smooth flow.

• Rosin Activated (RA) Core: Features an internal 2.2% flux core that clears oxides instantly, promoting excellent spreading across copper and brass surfaces.

• High Fluidity & Fast Wetting: Formulated to minimize solder defects such as bridging, icicles, and cold solder joints.

• Low Splatter & Reduced Fumes: Engineered for minimal flux spitting and low smoke generation to keep the workbench clean and improve visibility.

• Shiny, Corrosion-Resistant Joints: Leaves bright, aesthetically clean solder connections with non-corrosive residue under standard operating conditions.

Common Applications and Recommended Usage

The balanced melting behavior and high fluidity of Hiflo Soldering Wire make it suitable for a broad array of electrical tasks:

• Printed Circuit Board (PCB) Repair: Ideal for through-hole component soldering, DIP IC installations, and SMD rework.

• Cable & Connector Termination: Joins stranded copper wires, barrel jacks, terminal blocks, and custom cable harnesses securely.

• Consumer Appliance Servicing: Used by field service engineers to repair home electronics, audio gear, power supplies, and TV mainboards.

• Educational Labs & DIY Projects: Provides an easy-to-use solder option for electronics hobbyists and engineering students due to its forgiving melting temperature.

Operating Guidelines and Workplace Safety

Warning: This product contains lead (Pb). Lead exposure can be hazardous to health. Always solder in well-ventilated areas, avoid breathing fumes, and wash hands thoroughly after handling solder wire.

• Select the Right Temperature: Set your soldering iron station between 320°C and 360°C to allow the Hiflo Soldering Wire to flow freely without burning the internal rosin flux.

• Apply Wire to the Joint: Heat both the component lead and the PCB pad simultaneously with the iron tip, then touch the solder wire directly to the heated joint rather than the iron tip itself.

• Post-Solder Cleaning: While the RA flux residue is generally stable, cleaning the PCB with isopropyl alcohol (IPA) or flux remover after soldering ensures a pristine, long-term finish.
