Tin Wire Sn15 Pb85 100g 0.8mm: The perfect starter or trial size. This compact reel is excellent for repair technicians, hobbyists, or for low-volume tasks where portability is important. It allows users to test the performance of Tin Wire 15 85 without a large upfront investment.
Tin Wire Sn15 Pb85 400g 0.8mm & Tin Wire Sn15 Pb85 500g 0.8mm: These mid-range sizes are workhorses for busy repair shops and small to medium batch production. The Tin Wire Sn15 Pb85 500g 0.8mm reel offers a great balance between capacity and manageability, reducing the frequency of reel changes compared to the 100g size.
Tin Wire Sn15 Pb85 800g 0.8mm & Tin Wire Sn15 Pb85 1000g 0.8mm: These are the bulk industrial choices. The Tin Wire Sn15 Pb85 1000g 0.8mm reel maximizes value for high-throughput factory environments. It minimizes downtime for reloading and offers the lowest cost per gram, directly supporting the core advantage of a cheap price for bulk soldering operations on general circuit boards.
A primary reason for the popularity of Tin Wire Sn15 Pb85 is its significant cost advantage over the more common Solder Wire Sn60Pb40 alloy. This section breaks down the key differences.
Cost Savings: The higher lead content in Tin Wire 15 85 makes it substantially less expensive. For operations that go through kilograms of solder weekly, this translates to direct and considerable reductions in consumable costs.
Performance Considerations: Sn60Pb40 is a eutectic alloy with a sharp melting point (around 183°C), excellent flow, and strong, shiny joints. Tin Wire Sn15 Pb85 has a plastic range during melting, which can require slightly different technique. Its joints may appear duller and have lower tensile strength than Sn60Pb40. However, for many general circuit board soldering applications—such as through-hole components, wire terminations, and large tabs—the mechanical and electrical performance of Tin Wire Sn15 Pb85 is entirely adequate ("good enough"). The key is matching the alloy to the application's demands.
Best Use Cases: Choose Sn60Pb40 for fine-pitch SMD work, high-reliability military/aerospace applications, or where superior joint aesthetics are required. Choose Tin Wire Sn15 Pb85 for Circuit Board soldering in cost-sensitive bulk manufacturing, general electronics repair, educational settings, and for applications where leaded solder is still permissible.
The Tin Wire Sn15 Pb85 alloy finds its strength in specific, value-driven soldering environments. Its cheap price and reliable performance make it a staple in two main areas:

Proper Technique: Apply the iron tip to heat both the pad and the lead simultaneously. Then, feed the Tin Wire Sn15 Pb85 0.8mm into the junction, not directly onto the iron tip. Allow the solder to flow freely and form a concave fillet.
Manage Expectations: Joints will have a duller, grayer appearance compared to shiny Sn60Pb40 joints. This is normal for this alloy and does not necessarily indicate a cold joint. Focus on ensuring the solder has wetted all surfaces properly.
Ventilation: As with any soldering, ensure your workspace is well-ventilated to avoid inhaling fumes from the flux core.
For cost-conscious manufacturing and practical repair work, Tin Wire 15 85 stands out as a remarkably effective solution.
