Abstract
Abstract Nozzle structure suitable for bringing heated fluid into contact with a plurality of terminals of a modular electronic component to facilitate attachment of the component to a substrate or removal therefrom. The nozzle structure comprises a conduit forming member engageable with the component and with the substrate to form a heated fluid conduit extending around the periphery of the component, and a heated fluid delivery conduit coupled to the conduit forming member for delivering heated fluid to the heated fluid conduit to effect melting of solder or the like at the terminals of the component.

Claim 4
Dependent Claim
56 words
A nozzle structure according to claim 1, wherein said conduit forming means comprises a frame including a top plate and side members attached to said top plate, said top plate being adapted to contact an external surface of said component, and said side members being adapted to contact said substrate to form said heated fluid conduit.
Claim 5
Dependent Claim
61 words
A nozzle structure according to claim 1, wherein said delivery means comprises at least one heated fluid delivery conduit connected to said conduit forming means at a location such that when said conduit forming means is in contact with said component to form said heated fluid conduit, said heated fluid is delivered to said heated fluid conduit via said delivery conduit.
Claim 6
Dependent Claim
40 words
A nozzle structure according to claim 3, wherein said delivery means comprises at least one heated fluid delivery conduit connected to said frame for delivering heated fluid to said fluid conduit when said frame is in contact with said component.
Claim 7
Dependent Claim
32 words
A nozzle structure according to claim 5, wherein said top plate has four corner areas, and wherein two heated fluid delivery conduits are connected to said top plate at alternate corner areas.
Claim 8
Dependent Claim
37 words
