![]() ![]() For example, a desoldering pump is most useful to remove large amounts of solder at once, while desoldering braid is the best option for cleaning solder pads. There are various desoldering methods you can use, each with different benefits and situations in which they are the most useful. It is important to learn how to desolder while minimizing possible damage to components and circuit boards. I recommend practicing and experimenting on old circuit boards to get a feel for desoldering. When desoldering, experience helps you a lot in finding the sweet spots for the settings. ![]() Buying a quality device minimizes this difference. Keep in mind that the temperature displayed on the screen of your device can vary from the real output temperature. In practice, I usually find myself using the following settings: Deviceģ50 to 380☌ (660 to 720☏), with low to medium airflow. You do want to spread out the heat to reduce thermal stress on a single point, but doing so increases the desoldering time.Īs you can see, there are a lot of things to keep in mind when selecting the right temperature on your soldering iron or hot air rework station. Moving the nozzle back and forth over the desoldering area does the same. Holding the nozzle further from the component increases the area over which the heat spreads. If you are using a hot air rework station, the distance from the nozzle to the component. ![]() More layers means more copper, which means more heat being conducted through the board away from the component. These are large areas of metal that further increase the amount of heat required to desolder the component.
