Claim Text:
1. A portable pack, comprising: a portable supporting structure including first and second components for holding the substrate therebetween, the substrate carrying a microelectronic circuit and having a plurality of terminals connected to the microelectronic circuit; a plurality of contacts on the second component, the contacts matching the terminals for making contact to the terminals, a pressure differential cavity seal between the first and second components, the pressure differential cavity seal forming an enclosed pressure differential cavity together with surfaces of the first and second components; a pressure reduction passage formed through one of the components, the pressure reduction passage having an inlet opening at the pressure differential cavity and an outlet opening outside the pressure differential cavity; a first valve in the component having the pressure reduction passage, opening of the first valve allowing air out of the pressure differential cavity to move the first and second components relatively towards one another for ensuring proper contact between the contacts and the terminals, and closing of the valve keeping air from entering the pressure differential cavity; and a first interface, on the portable supporting structure and connected to the contacts, for connection to a second interface on a stationary structure when the portable supporting structure is removable and held by the stationary structure.
