A system for packaging integrated circuit components including a ball grid array substrate with a plurality of solder balls coupled to the substrate. A semiconductor device is mounted on the substrate and electrically coupled to the solder balls. One or more terminals are coupled to the substrate and electrically coupled to said semiconductor device. A detachable module contains auxiliary component, such as a data acquisition device, a wireless communications device, an output device or driving devices for a clock circuit. The module comprises a body portion for containing the component and one or more electrical connectors for mating with respective terminals to hold the module to the substrate and to electrically couple the component with the semiconductor device.
