Practical Guide to Corrosion Resistance Throughout the PCB Lifecycle

The core principle for addressing PCB corrosion is "prevention first, with repair as a supplement." This is because once corrosion occurs, the loss of the metal layer is irreversible. Repair can only mitigate faults and cannot restore original performance. Severe corrosion necessitates PCB replaceme
