Devices and their subassemblies typically undergo stresses during manufacturing and testing processes and during general use. To provide visual indication of stress or strain levels endured, a preferred embodiment includes frangible material deposited on particular isolated areas of devices and/or their subassemblies. The frangible material, when applied according to one methodical embodiment, provides visible indication of overstrain as cracks in the frangible material deposits, and of non overstrain when cracks are not visible.
