Lead-Free Solder Wire Thin 0.8mm 100g Electronics Soldering Rosin Flux Core Fine Gauge 0.032in Diameter Electrical Solder Unlead No Lead RoHS Sn99 Ag0.3 Cu0.7 Flow Well Soldering Wire

Description

Product Overview

The Enersystec Lead-Free Solder Wire 0.8mm is engineered for precision soldering in modern electronic assemblies. Featuring a 100‑gram spool of thin 0.032‑inch (0.8 mm) wire, the product combines a rosin‑flux core with a high‑performance alloy composition of Sn99 Ag0.3 Cu0.7. This blend delivers superior electrical conductivity, low melting point, and excellent wetting characteristics, allowing technicians to create clean, strong joints on delicate printed circuit boards (PCBs) and component leads. The wire is RoHS‑compliant, ensuring it contains no hazardous lead, making it safe for both the environment and the end user. Dimensions of the packaging are compact (2 × 2 × 1.7 in), facilitating easy storage in workbenches or toolboxes. With a two‑year warranty and a proven track record of 4.6‑star customer satisfaction, this solder wire meets the rigorous demands of hobbyists, repair shops, and industrial engineers alike.

Usage

Designed for a wide range of applications, this 0.8 mm lead‑free solder wire excels in fine‑pitch soldering, surface‑mount technology (SMT) rework, and prototype development. Its thin gauge enables precise heat transfer, reducing the risk of thermal damage to sensitive components such as micro‑controllers, sensors, and high‑frequency modules. Whether you are assembling a hobbyist Arduino shield, repairing a smartphone motherboard, or performing large‑scale manufacturing of consumer electronics, the rosin‑flux core provides consistent wetting and eliminates the need for additional flux. The wire is compatible with standard soldering irons, hot‑air rework stations, and wave soldering equipment, offering flexibility across various soldering environments. Users appreciate the clean, bright solder joints that require minimal post‑solder cleaning, streamlining production workflows and reducing overall turnaround time.

FAQ

What is the recommended soldering temperature for this wire?

The optimal temperature range is between 350 °C and 380 °C (662 °F‑716 °F). Operating within this window ensures proper melting of the alloy while protecting sensitive components from overheating.

Can this solder wire be used with a hot‑air rework station?

Yes, the 0.8 mm diameter and rosin‑flux core are fully compatible with hot‑air rework stations, making it suitable for component removal and re‑placement on PCBs.

Is the solder wire suitable for aerospace or medical device manufacturing?

While the wire meets RoHS standards and offers high reliability, specific aerospace or medical certifications may require additional testing. Consult your regulatory compliance team for project‑specific requirements.

How many joints can be made from a 100 g spool?

Typical joint consumption varies by project, but a 100 g spool generally yields between 300 and 500 average‑size solder joints, depending on joint size and solder usage efficiency.

What should I do if the solder does not flow properly?

First, verify that the soldering iron is set to the correct temperature range. Ensure the tip is clean and properly tinned. If issues persist, check the spool for moisture exposure and allow the wire to acclimate to the work environment before use.
