What are the two types of drying ovens used in avionics corrosion control?

The correct answer identifies the two types of drying ovens used in avionics corrosion control as circulating air and forced air. These types of drying ovens are critical in ensuring that moisture is effectively removed from electronic components and assemblies, as moisture can lead to corrosion and other detrimental effects on avionics systems.

Circulating air drying ovens typically use a fan to circulate warm air throughout the oven chamber, which allows for even drying of components. This is particularly effective because the constant movement of air helps to evaporate moisture consistently from all surfaces.

Forced air drying ovens, on the other hand, not only circulate air but also enhance the airflow with higher velocity. This means that the drying process is expedited as the forced air rapidly removes moisture from the items being dried. The increased air movement aids in maintaining an optimal temperature and humidity level inside the oven, enabling efficient and effective drying.

By using either of these methods, avionics technicians can ensure that components are thoroughly dried before they are put back into service, thereby minimizing the risk of corrosion.
