ABSTRACT:
A crash-hardened memory device in which only a single electronic component, such as a memory chip, mounted on a small printed circuit board (PCB), is protected against an impact. The portion of the PCB containing the electronic component is wrapped in fire-retardant material and RF shielding tape. The wrapped PCB assembly is placed in a rigid, hardened enclosure which provides an environmental seal for the portion of the PCB containing the electronic component. A portion of the PCB extends outside of the enclosure to allow electrical connections to be made to the electronic component contained inside. A score line is created on the PCB to create an acceptable shear point between the internal and external portions of the PCB in the event of a crash. Threaded fasteners extend through and beyond both enclosure halves to provide a means for mounting the crash-hardened memory device on an external surface.
