Abstract

An electrical device is described for use in an automotive vehicle. The device includes a printed circuit board (PCB) having first and second sides. The PCB is adapted for multiple electronic components to be mounted to the first side, including a first component at a first position and a second component at a second position. The second component is capable of substantially blocking airflow directed substantially across the first side from at least one direction toward the first component. The PCB defines a plurality of apertures formed in a region of the PCB including the first position such that airflow directed substantially across the second side of the PCB flows through the apertures, under the first component at the first position on the first side of the PCB, and on a portion of the first side of the PCB beyond the region of the PCB including the first position.
