High-Quality Solder at Competitive Price

About this item

Kester Solder 24-6337-0018 is a high-quality solder wire designed for electronics and industrial applications, available in India through crowcrowcrow, with a 1lb spool of 63/37 tin-lead alloy. Its activated rosin core provides fast, reliable wetting, making it ideal for precise PCB assembly and repair.

The flux's high mobility ensures quick spreading, reducing soldering time and improving joint quality. Reviewers in humid Indian cities report consistent performance with minimal rework, even on delicate components. Its classification as ROM1 per J-STD-004 confirms industry-standard safety and performance.

Imported directly from the USA, this solder offers a cost-effective, durable solution for professionals and hobbyists in India. With all duties included, it arrives in 12-14 days, ready for immediate use, supporting your projects with trusted quality.

Key Features

  • This solder has virtually dominated the field of activated rosin core solders for well over four decades
  • An outstanding performance feature of this flux is the “instant-action” wetting behavior
  • The high mobility and fast-spreading action of this flux results in more reliable production line soldering
  • Classified as ROM1 per J-STD-004
  • 1 LB Spool

Why choose this product

Superior Flux Composition for Consistent Results

Kester's flux is formulated for high mobility and instant wetting, reducing soldering time and rework. Its industry classification as ROM1 confirms safety and reliability, making it suitable for professional electronics assembly in India.

Ideal for Professional & Hobbyist Use in India

Designed for precise PCB soldering, this solder wire performs reliably in humid, warm Indian climates. Skip if working with lead-free requirements—this is a tin-lead alloy, not RoHS compliant.

How to use

  • Prepare the workspace — Ensure good ventilation, clean the PCB surface, and set the soldering iron to appropriate temperature (~350°C).
  • Apply solder — Hold the soldering iron tip on the joint for 2-3 seconds, then feed the flux-core solder wire until the joint is properly wetted.
  • Finish and clean — Remove heat, inspect the joint for smoothness, and clean flux residues with isopropyl alcohol if needed.
