How strong is soldering?

Soldering creates a strong electrical and mechanical connection between components by melting a filler metal, usually a lead-tin or lead-free alloy, which solidifies upon cooling. While solder joints can be quite durable for electronic applications, they are generally not as strong as traditional welding or brazing methods. The strength of a solder joint depends on factors such as the materials being joined, the solder used, and the quality of the soldering process. Proper technique and surface preparation can enhance the strength and reliability of the joint.
