Solder provides the metallic bond that holds electronic assemblies together, whether joining wires, through‑hole parts or surface‑mount devices. Solid wire sold in tubes or spools is available in common 0.031 in and finer 0.020 in diameters, giving control over heat transfer and joint strength for both beginner and experienced users. Lead‑based alloys, typically 63 % tin and 37 % lead, melt at lower temperatures and flow easily, making them suitable for rapid prototyping and repair work. Lead‑free versions use a water‑soluble flux that leaves minimal residue, supporting compliance with safety standards and simplifying post‑solder cleaning. Solder paste, supplied in measured packs, enables stencil‑based application for dense SMD layouts, offering consistent deposition and reliable reflow results. Choosing the appropriate form, alloy composition and flux type ensures compatibility with component sizes, thermal budgets and the desired durability of the finished circuit.
