What effect does low humidity have on soldering?

While low humidity can indeed reduce certain types of contamination in the assembly environment, it is important to evaluate this aspect in the context of soldering. Low humidity conditions can minimize moisture absorption by components and printed circuit boards, which helps in preventing issues related to water intrusion, such as hydrolytic degradation or solder joint defects due to trapped moisture.

However, low humidity does not directly enhance solder joint quality or promote better soldering practices overall. In fact, too low humidity can lead to increased oxidation of metal surfaces because the lack of moisture can make surfaces more prone to forming oxide layers.

In the realm of soldering, moisture control is crucial for overall assembly quality. Although low humidity can reduce some contamination risks, it also poses its own challenges with oxidation, which is a significant factor in solder joint reliability. Thus, while reducing contamination might seem beneficial, it is not the most comprehensive answer regarding the overall effect of low humidity on soldering processes.
