Zusammenfassung:	A method includes providing a printed circuit board ("PCB") supporting a solderable component, and supporting a first fuse on the PCB, where the first fuse includes a first temperature-sensitive element that measurably changes in response to exposure to ambient thermal conditions exceeding a first threshold temperature. The PCB, the solderable component, and the first fuse define an apparatus. The method includes performing a PCB assembly manufacturing process, and then testing the first fuse to determine whether, during the PCB assembly manufacturing process, the first fuse was exposed to ambient thermal conditions exceeding a first threshold temperature. The first threshold temperature is a minimum temperature where the PCB assembly manufacturing process is to be carried out, a maximum temperature at which the PCB assembly manufacturing process is to occur, or a first intermediate temperature between the minimum and maximum temperatures.
