    摘要: A principle of surface interlocking wherein the imperfections of two parallel surfaces deform and interlock under pressure. The surface interlocking enables the combination of a bridging element and a bonding tip of a diffusion bonding apparatus to pick up, transport, position at a unique location, and bond the bridging element in place to the conductors or pads. In the invention a single point bonding tip as part of a bonding apparatus is used to pick up the, to be, bridging metal object transport it to the bonding site and perform the entire bridging bonding operation all in one sequence of steps.

    摘要: In a bonding station the parts of the apparatus to be bonded are retained at a thermal bias temperature at a permitted level and a thermal check valve interface is provided between the bonding location and the part of the station that would serve as a conduction heat sink, thereby thermally insulating other uninvolved parts of the structure and and confining the bonding heat to the bonding region. Such confinement reduces the dwell time that the bond must remain at the bonding temperature. The bonding station has a number of features: the parts to be bonded are maintained on a support member that is provided with a heat biasing capability that can establish the assembly at a specified temperature; a retention capability, such as the use of vacuum, is provided to maintain registration and thermal contact of the part with the support; and a thermal check valve capability is provided to control the rate of heat flow through the support member so that locallized heat is controlled in dissipation.

    摘要: In alignment of superpositioned objects on opposing substrates accuracy and simplicity is achieved through relative movement of the substrates responsive to an image of one object reflected from the surface of the opposite substrate. Alignment of mating fine pitch conductors and pads for bonding is achieved by observation of the reflection of one conductor or pad in the surface of the opposite substrate and relatively moving the substrates to eliminate the reflection.

    摘要: In a bonding station, a tooling principle is provided wherein first and second tool parts respectively hold first and second apparatus parts, each apparatus part having fine conductor periodicity edge bonding regions, in superpositioned registration with the tool parts providing space and accessability for optical alignment and for bonding heat and pressure. The tool members retain a first, position registered, apparatus part, with "X" - "Y" registration capability, in position with an edge bearing a fine conductor periodicity accessable by a tapered edge of the tool which permits optical fine alignment adjustment and bonding heat and pressure application.
