Flux-105 Swg-22 Sn/pb-60/40 Make -bt Composition: Common mixes include 60% Tin / 40% Lead (60/40) or 63% Tin / 37% Lead (63/37), known for good flow and lower melting points (around 183°C). Lead-free options (tin-copper, tin-silver) are also available. Flux Core: Contains an internal flux that cleans surfaces, prevents oxidation, and helps solder flow evenly for better adhesion. Gauge/Diameter: Comes in different thicknesses, such as 22 SWG (Standard Wire Gauge, approx. 0.7mm) or 18 SWG, suitable for fine electronic work or heavier joints. Performance: Known for user-friendly, seamless connectivity, high-temperature stability, and good results in DIY, electronics repair (TVs, toys, circuits), and general electrical work. Packaging: Often sold on spools (reels) in weights like 250g or 500g. Common Applications: Repairing circuit boards. Connecting wires in electronics. Home improvement and small electrical appliance repairs. In essence, BT Solder Wire provides reliable, easy-to-use solder for various soldering tasks, offering
