The global push for environmental responsibility means manufacturers across India must embrace the lead-free transition. Achieving RoHS compliance is no longer optional; it is a necessity for accessing major export markets and demonstrating sustainable practices. This shift, however, brings technical challenges, especially in wave soldering.
As a trusted solder wire manufacturer based in Pune, Kothari Metsol guides you through this change. Discover how to select the right lead-free solder sticks and solder bars to ensure your production remains efficient, reliable, and defect-free. Invest in quality now to secure your future in manufacturing.
The Critical Challenge: Higher Temperatures for Lead-Free Solder Bars
Moving from traditional Tin/Lead (Sn/Pb) solder to lead-free alternatives fundamentally changes your process. Lead-free alloys demand higher heat, creating thermal challenges for your equipment and components.
Why Temperatures Rise
Lead-free solder stick alloys, such as Sn/Ag/Cu (Tin/Silver/Copper), typically melt at temperatures about 30°C to 40°C higher than leaded solder.
- Impact on Machinery: Your wave soldering machines and solder pots face increased thermal stress. You must check that your equipment handles these higher operating temperatures reliably and safely.
- Increased Risk: Higher temperatures can stress PCB laminates and sensitive components. This makes the soldering window—the margin for error—much smaller. Ensure precise temperature control to avoid component damage and weak solder joints.
The High-Purity Solution: Minimizing Defects at Critical Heat
When you operate at higher temperatures, the purity of your material becomes even more critical. Impurities in low-quality solder bars oxidize faster, leading to excessive dross and potential joint failures.
Why High-Purity Lead-Free Solder Sticks Matter
Kothari Metsol manufactures high-quality lead-free solder sticks from virgin metals. This unwavering commitment to purity is your defense against high-temperature defects.
- Reduces Dross: High-purity metal minimizes contaminants that react with oxygen at high heat. Less dross means less waste and lower operational costs. See the difference in your production line immediately.
- Better Wetting: Pure alloys flow and “wet” surfaces beautifully, even at the required higher temperatures. This ensures complete coverage and strong metallurgical bonds, helping you achieve a zero-defect rate.
- Consistent Flow: Virgin-metal solder bars provide predictable flow characteristics, which is crucial for high-speed wave soldering. Use Kothari Metsol’s consistent quality to upgrade your process stability.
