Process Window Index (PWI) is a statistical measure that quantifies the robustness of a manufacturing process which involves heating and cooling, known as a thermal process. In the electronics manufacturing industry, PWI values are used to calibrate the heating and cooling of soldering jobs (known as a thermal profile) while baked in a reflow oven.
