What Size Solder For Circuit Boards

By | February 3, 2023



If you've ever wanted to build or repair a circuit board, you know that it's important to use the right type and size of solder. But how do you know which one is right for your project?

The type and size of solder you use depends on the project you're doing, but there are some general guidelines you can follow. The most common types of solder used for circuit boards are resin core and rosin flux core. Resin core solder is a single-component material made from copper and a resin that helps bind the copper together. Rosin flux core solder is a two-component material composed of port flux and copper. The port flux helps create a better bond between the copper joint and the circuit board.

The size of the solder you'll need to use also depends on the project. For large projects, you may need to use thicker solder like 0.8mm or 1.2mm. Smaller projects may require thinner solder such as 0.6mm or even 0.4mm. When working with components on a circuit board, the smallest possible solder should be used to ensure the best connection and to avoid overcrowding. It's also important to use the correct temperature setting on your soldering iron - too hot and you could damage the components, but too low and the solder won't stick.

When choosing solder for your project, it's important to consider the type, size, and temperature of the material rather than just picking the first thing you see. Solder supplies are available at most hardware and electronics stores, so take your time and make sure you get the right type and size for your project.

So whether you're a beginner or an experienced circuit board builder, keep these tips in mind when selecting solder for your project. With the right type and size of solder at the right temperature setting, you can ensure a good connection and successful project.
