Abstract
Disclosed is a device and method for intelligently heating a component of a printed circuit board (PCB) to bring it within a specified operating temperature range quickly. A temperature sensor positioned in proximity to the component and is coupled with a logic circuit that receives a reading from the temperature sensor and compares it to a threshold temperature value. A heating element positioned in proximity to the component is coupled with a power source and a switch. The switch is triggered by the logic circuit to activate the heating element when the temperature sensor reading is cooler than the threshold temperature value thereby causing the component to warm up. The switch is triggered again by the logic circuit to de-activate the heating element when the temperature sensor reaches the threshold temperature value or a predetermined timeout period expires.
