Abstract
Apparatus and method for directly detecting the atmospheric conditions leading to creep corrosion of printed circuit boards (PCBs) well before the PCBs in the computers start suffering from creep corrosion. The embodiment indicates the propensity of the air towards creep corrosion on PCBs. Additionally, to avoid the false reading due to condensed moisture, condensed moisture may be avoided by using a heater attached to the creep corrosion monitor that keeps the creep corrosion monitor above the dew point temperature.
