Corrosion can cause shorts and what other negative effect in printed circuits?

In printed circuits, corrosion can lead to increased resistance, which is a significant concern for the overall functionality of electronic components. When corrosion occurs, it typically forms an insulating layer on the conductive pathways, which disrupts the flow of electrical current. This increased resistance can result in devices not operating at their intended efficiency, leading to poor performance.

Increased resistance affects the power consumption and can generate excess heat as the circuit tries to deliver the necessary current through an obstructed pathway. This not only impacts the performance but can also potentially lead to other issues, such as overheating or degradation of the circuit materials over time.

Other effects of corrosion, while relevant, do not encapsulate the immediate electrical impact as directly as increased resistance does. Understanding this relationship is crucial for maintaining the reliability of avionics systems and ensuring proper function in printed circuit boards.
