What may happen if the solder joint is not properly formed?

When a solder joint is not properly formed, it may lead to weak connections. Proper soldering techniques ensure that a strong metallurgical bond is created between the components being joined. If the joint is not made correctly, it can result in inadequate adhesion, poor mechanical strength, and increased susceptibility to thermal and mechanical stresses. This ultimately compromises the integrity of the connection, which can result in failure during operation or use.

For instance, improper heating can prevent the solder from flowing adequately, leading to cold joints that do not bond well. Similarly, using the wrong solder for the materials involved can lead to poor interaction, weakening the joint further. As a result, ensuring a properly formed solder joint is critical to maintaining the reliability and functionality of the assembly.
