How to buy an original Kester 63/37 Sn/Pb Solder Wire in India?

Purchase Kester 63/37 Sn/Pb solder wire from authorized US retailers and authorized brand partners, imported per order by crowcrowcrow. It arrives factory-sealed with all customs duties and GST included. Delivery is via ExpressBox tracked shipping within 12-14 days.

What is the difference between 60/40 leaded solder and lead-free solder?

60/40 solder contains 60% tin and 40% lead, offering a lower melting point around 183°C–190°C and easy wetting for hobbyist electronics and repair. Lead-free solder typically consists of tin-silver-copper alloys melting at higher temperatures (around 217°C) to meet RoHS environmental safety standards.

Do I need separate flux when using rosin-core solder wire?

Kester 245 flux-cored solder wire contains integrated flux channels that activate upon heating to clean surface oxides. For routine PCB joints, the internal core is sufficient, though supplementary external flux paste is recommended for heavily oxidized surfaces or fine-pitch SMD soldering.

Is Kester 63/37 Sn/Pb solder wire safe for electronics work in India?

Yes, this solder is excellent for electronics work. However, it contains lead, a toxic heavy metal. Always use in a well-ventilated area and wash hands thoroughly after use. It is not RoHS compliant, so avoid using it for export electronics or applications requiring strict environmental regulations.

What are the benefits of using Kester 63/37 Sn/Pb solder wire?

This solder offers superior wetting and a low melting point (183°C), creating strong, reliable joints ideal for delicate electronics. The 0.02" diameter allows for precise application, and the 1 lb spool provides ample material for numerous projects.

Can I use Kester 63/37 Sn/Pb solder wire for plumbing in India?

No, this solder is specifically designed for electronics soldering. It contains lead and is not suitable for plumbing applications, which require lead-free or specialized plumbing solder alloys to meet safety and regulatory standards.

What is the best Kester 63/37 Sn/Pb solder wire?

The Kester 63/37 Sn/Pb solder wire, 1 lb spool, 0.02" diameter, is highly regarded for its performance in electronics soldering due to its excellent wetting properties and low melting point.

Are there side effects of using Kester 63/37 Sn/Pb solder wire?

The primary concern is lead exposure, a toxic heavy metal. Ensure proper ventilation and wash hands after use. This solder is not RoHS compliant, meaning it cannot be used for certain export electronics or applications requiring strict environmental regulations.

Why choose this product

Superior Electronics Soldering Performance

Kester 63/37 Sn/Pb solder wire is engineered for precision electronics work. Its 63% tin and 37% lead composition provides excellent wetting and a low melting point of 183°C, ensuring strong, reliable joints on circuit boards. Unlike generic local alternatives, this USA-sourced solder offers consistent performance, minimizing the risk of cold joints or component damage. It's the professional's choice for intricate soldering tasks where quality and dependability are paramount.

Ideal for Hobbyists & Professionals

This solder is perfect for electronics enthusiasts, DIYers, and professionals working with through-hole components. Its 0.02" (0.508mm) diameter wire allows for precise application, while the 1 lb spool provides ample material for numerous projects. While not RoHS compliant, it excels in applications where leaded solder is acceptable and preferred for its ease of use and superior joint quality. For those needing lead-free options, explore our other product lines.

How to use

Ensure good ventilation by working near an open window or using a fume extractor. Clean your soldering iron tip and tin it with a small amount of solder. Have your electronic components and PCB ready. — Prepare the Work Area
Apply the heated soldering iron tip to both the component lead and the PCB pad simultaneously for 1-2 seconds to heat them evenly. The iron tip should be hot enough to melt the solder instantly. — Heat the Joint
Touch the Kester solder wire to the heated joint (not the iron tip). The solder should flow smoothly and evenly around the component lead and pad, forming a shiny, concave fillet. Remove the solder wire first, then the iron. — Apply Solder
Allow the joint to cool naturally. Inspect for a shiny, smooth connection. If dull or balled, reheat and add a tiny bit more solder. Clean any flux residue with isopropyl alcohol if necessary. — Inspect and Clean
