Abstract
A method includes identifying a microelectronic device located at an air bearing surface. The method further includes identifying a resistive heating element electrically isolated the said microelectronic device; applying a bias current through the resistive heating element to generate localized heat to heat the microelectronic device; identifying a predetermined humidity threshold and a separation distance between the microelectronic device and the resistive heating element in at least one dimension; measuring an ambient temperature at the air bearing surface; measuring an ambient relative humidity at the air bearing surface; determining an effective temperature; and adjusting the bias current to heat the microelectronic device to the effective temperature. The resistive heating element is one of a plurality, and at least two of the plurality of resistive heating elements are powered from a common source such that at least two of the resistive heating elements are commonly controllable via a common source.
