What should be done if components become overheated during soldering?

When components become overheated during soldering, it is crucial to assess for damage and replace them if necessary. Overheating can adversely affect the functionality and reliability of electronic components, potentially leading to catastrophic failures in the final assembly.

Components such as semiconductors and certain passive devices have thermal limits, and exceeding these can change their electrical characteristics, create internal faults, or even physically damage them. Thus, evaluating the components after overheating ensures that any which have sustained damage can be identified and replaced, preserving the overall integrity of the assembly.

The choice to ignore the overheating disregards the potential for component failure, which can lead to future reliability issues. Continuing to solder without interruption can exacerbate any damage already incurred, and cooling overheated components with water can introduce moisture and other contaminants that may further compromise component performance and reliability. Therefore, a thorough assessment and careful consideration of component condition is the appropriate response when overheating occurs.
