Abstract
Abstract The invention is a device for attaching or removing electronic components from a substrate and includes a nozzle for delivering heat to the terminal areas of the substrate. The nozzle includes a first plate, spaced from the component, having openings corresponding to the terminals of the component. The nozzle further includes a second portion below the plate for directing heated fluid to the component. Further, at least one opening in the plate is enlarged to delivery more heat to certain terminals connected to a ground plate, for example.

Claim 1
Independent Claim
244 words
A device for attaching modular electronic components to or removing them from a substrate where each said component has a plurality of terminals extending from the periphery thereof, said device comprising: heater means having at least one passage extending therethrough for heating a fluid flowing through said passage; first nozzle means disposed at one end of the heater means, said first nozzle means being spaced from and above said plurality of terminals of said components when in its working position, said first nozzle means including a plate having a plurality of nozzle openings where the configuration of the plurality of openings generally corresponds to that of the plurality of terminals of the component and where the heated fluid from the heater means flows through the nozzle openings; second nozzle means disposed adjacent to said first nozzle means on the side of said first nozzle means opposite said heater means for directing the heated fluid flowing through the nozzle openings to the terminals of the substrate; and at least one of said nozzle openings being larger in diameter than the remaining openings, said at least one of said nozzle openings being positioned substantially directly over at least one of the component terminals where said one terminal is connected to a ground plane or the like disposed at said substrate so as to provide more heat to said one terminal, said heated fluid being urged through said plurality of nozzle openings towards said plurality of terminals.
