how to know if solder joint is good

Soldering is an important skill to have when it comes to repairing electronics, but it can be difficult to know if a solder joint is good or not. Knowing what to look for in a good joint can help ensure that your repairs are reliable and long-lasting. In this article, we’ll take a look at what a good solder joint looks like and how you can test the quality of your joints.

First, let’s talk about what a good solder joint looks like. A good solder joint should have a smooth, shiny appearance to it, with no bumps or irregularities. The heat of the soldering iron should be evenly distributed throughout the joint, ensuring that the flux has fully melted and the metals have fused together. It should be possible to see the point where the two metals meet, as well as a few millimeters of the solder wire around it. When you’re done soldering, the area should be free from any excess solder or residue.

Testing the quality of the solder joint is also important. You can use a multimeter to check the electrical connection of the joint. This will let you know if the joint is properly conducting electricity or not. It’s also good to do a visual inspection of the joint and make sure that there aren’t any breaks or gaps in it. Additionally, you can use a continuity tester to check the flow of current through the joint. This can help identify any potential weak points in the joint that need to be addressed.
