What Size Soldering Iron For Circuit Boards

By | February 15, 2023



For those interested in electronics and circuit building, soldering is an essential skill. While all soldering irons are essentially the same in terms of design and function, selecting the correct size for the job can be a tricky decision. In this article, we’ll discuss what size soldering iron for circuit boards is best.

When it comes to soldering on a circuit board, a smaller tip size is typically preferred. This is because most circuit boards are very small and intricate and require precision. The majority of circuit boards require a soldering iron with a tip size of between 0.5mm and 1mm. Anything larger may damage delicate components.

The heat generated by the soldering iron is also an important factor to consider when selecting the size of the tip. For circuit board soldering, you want a soldering iron with a temperature range of between 350-400 degrees Celsius. Anything too hot or too cold could damage components.

It’s important to choose the right type of soldering iron for the job. Soldering irons come in several different forms, such as soldering gun, soldering station, and soldering pencil. A soldering gun is great for larger projects, while the soldering station is ideal for precise and intricate work. The soldering pencil is the best choice for working on circuit boards, offering good control and easy maneuverability.

Finally, it’s important to practice proper safety when using a soldering iron. Always make sure the area is well-ventilated or wear a respirator if necessary, as the fumes from soldering are hazardous. Also, be sure to use appropriate eye protection and protective gloves as the tip of the soldering iron can get incredibly hot.

In summary, when selecting the right size soldering iron for circuit boards, it’s important to choose one with a tip size between 0.5mm and 1mm and a temperature range of 350-400 degrees Celsius. The soldering pencil is the best choice for circuit boards, and make sure always to practice proper safety measures when using a soldering iron.
