China 800 Gram Soldering Wire

Product Configuration

This is a consumable material and does not have “configuration” in the electronic sense. However, correct usage is critical:

Identify the Alloy: Check the product label to confirm the alloy type (e.g., Sn60Pb40 or Sn99Cu0.7Cu). This determines the melting temperature and application.

Sn60Pb40 (Leaded): Melts at ~183-190°C. Easier to use, shinier joints.
Sn99Cu1 (Lead-Free): Melts at ~227°C. Requires higher temperature, joints are duller.

Check the Diameter: The spool will have a specific diameter (e.g., 1.0mm, 0.8mm). Choose the right diameter for your work:

Thicker (1.0mm+): Better for large wires, connectors, and through-hole components.
Thinner (0.5-0.8mm): Ideal for precision electronics and surface-mount components.

Use with Appropriate Equipment:

Temperature Setting: Set your soldering iron temperature according to the alloy. For lead-free, a higher temperature (320-380°C) is needed.
Iron Tip: Use a clean, properly tinned tip that is large enough to transfer heat efficiently for the size of the joint.

Standard Soldering Technique:

Heat the joint (both the component lead and the PCB pad) with the iron tip.
Apply the solder wire to the joint, not directly to the iron. The heated joint should melt the solder, allowing it to flow smoothly.
Use the flux core to your advantage—the solder should flow easily if the surfaces are clean and hot enough.

Warning: Always work in a well-ventilated area. The fumes produced from soldering, especially from the flux, are irritants and should not be inhaled.

Economy Size: A large 800-gram (0.8 kg) spool of solder wire, designed for high-volume usage.
Common Alloy: Typically a leaded (e.g., Sn60Pb40) or lead-free (e.g., Sn99Cu1) alloy, suitable for general-purpose soldering.
Rosin Core: Contains a flux core (often rosin RMA) to clean surfaces and improve solder flow.
General Application: Ideal for factories, repair shops, or serious hobbyists who require a large quantity of solder for frequent use.
Value Pack: Offers a lower cost per gram compared to small consumer spools.

Product Description

This product is a bulk 800-gram spool of soldering wire, commonly manufactured for industrial, commercial, and high-volume DIY use. It is designed to provide a cost-effective solution for environments where soldering is a frequent task, such as electronics assembly lines, repair workshops, or for dedicated hobbyists. The solder wire itself is typically a standard alloy; the most common types are reliable leaded variations like 60/40 Tin/Lead (Sn60Pb40) for its ease of use and low melting point, or lead-free alternatives like 99.3% Tin/0.7% Copper (Sn99Cu1) to comply with environmental regulations (RoHS).

The wire features an internal core filled with rosin (RMA) flux. As the solder melts, the flux is released to clean the metal surfaces of oxidation, prevent new oxidation from forming, and significantly improve the wetting and flow of the molten solder, resulting in strong, shiny, and reliable connections. The large spool size minimizes the need for frequent replacement, ensuring continuous workflow and reducing long-term material costs. It is a practical, no-frills workhorse product for users whose primary concern is volume and value.

High Capacity: The 800-gram quantity is ideal for prolonged use without the interruption of changing spools.
Cost Efficiency: Purchasing in bulk dramatically reduces the cost per gram compared to standard retail-sized packages.
Consistent Performance: Designed for manufacturing, it offers consistent diameter and flux content for reliable results batch after batch.
Versatile Use: Suitable for a wide range of applications, from PCB assembly and repair to general electrical soldering and light metalwork.
Improved Workflow: Reduces downtime in professional settings, contributing to higher productivity.
