Abstract
An apparatus comprises a matrix of thermoelectric devices for applying thermal gradients across an electronic component mounted in a PCB substrate within an enclosed housing. A matrix of thermosensitive devices are placed around the perimeter of the electronic component to measure thermal gradients associated with the component. A controller controls the matrix of thermoelectric devices based on the thermal gradients measured by the matrix of thermosensitive devices with a matrix of thermocouple coefficients.
