Why choose this product

Premium USA-Quality Solder

Kester flux-cored solder is a trusted name in electronics, offering consistent quality, no-clean flux, and superior wetting. Designed for professional and hobbyist use in India, it supports high-reliability assemblies with minimal post-solder cleaning.

Ideal for Indian Electronics Makers

This solder's no-clean flux and 63/37 alloy support precise, durable joints in humid, high-temperature Indian environments. Suitable for PCB assembly, repairs, and prototyping, it ensures clean, professional results for Indian technicians and hobbyists.

How to use

  • Prepare the workspace — Ensure good ventilation, clean the PCB, and set the reflow temperature to 183°C–190°C for optimal melting.
  • Apply solder — Feed the 0.031" diameter solder wire to the joint, heating with a soldering iron until the flux activates and the solder flows smoothly.
  • Inspect and reflow if needed — Check for proper wetting and joint shape. Reheat if necessary to improve connection quality.

FAQ, See What Others Asked

What is the difference between 63/37 solder and lead-free solder?
63/37 solder contains 63% tin and 37% lead, offering a lower melting point (~183°C) and excellent wetting for electronics. Lead-free alloys melt at higher temperatures (~217°C) and meet RoHS standards, but may require adjustments in soldering process.
Do I need external flux when using this flux-cored solder?
No, this solder contains integrated rosin flux, which activates during heating to clean surfaces. External flux is generally unnecessary unless working on heavily oxidized surfaces.
