What type of corrosion is the principal form of attack for ESDS devices?

The principal form of attack for Electrostatic Discharge Sensitive (ESDS) devices is galvanic corrosion. This type of corrosion occurs when two different metals are placed in contact with one another in the presence of an electrolyte, leading to an electrochemical reaction that results in the degradation of one of the metals. For ESDS devices, which are particularly vulnerable to electrical and electrochemical interactions, galvanic corrosion can significantly compromise their operation and reliability.

ESDS devices often use various metals and materials that may not be compatible when in contact under certain environmental conditions. This can lead to unintended current flows that cause localized corrosion, thereby damaging the device. Recognizing the susceptibility of these devices to galvanic interactions is critical for effective corrosion control and ensuring their longevity and performance in various applications.
