Printed circuit boards (PCB) are the fundamental component of an electronic system. PCB’s performance enhances the performance of the entire device. With miniaturization of devices, the heat generated per unit area has increased. This, in turn, will make the components within the device to malfunction, reducing the lifetime of the device. The major heat-generating components in an electronic device are microprocessors, transistors, resistors, batteries, solder joints, and copper traces.
