Abstract
Abstract A device for desoldering one or more soldered connections wherein a heat conductive head member is provided with several projections for simultaneously contacting and melting each soldered connection. The soldered connections are isolated from each other during the melting operation to prevent any flow of melted solder, and means are carried by the heat conductive member for discharging the melted solder from the connections. A method of desoldering one or more soldered connections.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
97 words
A device for desoldering a plurality of soldered connections on a support member, said device comprising a heat conductive member having a plurality of projections extending therefrom and extending in a pattern corresponding to the pattern of said soldered connections for simultaneously melting said connections each of said projections being spaced from its adjacent projection and having a a cavity means formed therein for receiving said connections, to concentrate heat in one of said pattern and to prevent the flow of melted solder along said support member, and means for applying heat to said heat conductive member.
Claim 2
Independent Claim
97 words
A device for desoldering a plurality of soldered connections on a support member, said device comprising a heat conductive member having a plurality of projections extending therefrom and extending in a pattern corresponding to the pattern of said soldered connections for simultaneously melting said connections each of said projections being spaced from its adjacent projection and having a a cavity means formed therein for receiving said connections, to concentrate heat in one of said pattern and to prevent the flow of melted solder along said support member, and means for applying heat to said heat conductive member.
Claim 3
Dependent Claim
23 words
The device of claim 1 further comprising means for discharging said melted solder from the vicinity of said projections and said support member.
Claim 4
Dependent Claim
44 words
The device of claim 2 wherein said means for discharging said solder comprises means to direct pressurized fluid through said projections and to the melted solder in said cavities to blow the melted solder from the vicinity of said projections and said support member.
Claim 5
Dependent Claim
28 words
The device of claim 1 further comprising a handle releasably secured to said heat conductive member, said handle including means for causing said heating means to be heated.
