Abstract

A pair of platelike metallic jaws are secured to a resilient clamp which urges the jaws in engagement with sets of metallic terminals at opposite sides of electrical components such as integrated circuit modules, so that when lead wires of the terminals are soldered or unsoldered, heat is dissipated by the jaws and clamp to prevent damage of the component by excessive heat. The clamp also provides a handle for the device, so that the component held between the jaws may be conveniently manipulated during installation or removal.

Claims

1. For use on an electrical component which is provided at its opposite sides with sets of metallic terminals and lead wires projecting from said terminals below the component;

a device for handling such a component and dissipating heat therefrom during performance of soldering operations on the lead wires, said device comprising a pair of coacting platelike jaws formed from heat conductive material formed and adapted to receive a component therebetween while engaging metallic terminals at the opposite sides of the component, and resilient clamp means secured to said jaws and biasing the same toward each other for releasably retaining the component between the jaws, said clamp means constituting a handle for thE device, wherein said jaws have lower edges and are provided with slots extending upwardly from said lower edges whereby to separate each jaw into a set of spaced-apart fingers engageable with the respective terminals of the component.

2. The device as defined in claim 1 wherein said jaws have lower edges and are provided at said lower edges with inturned portions constituting seats engageable with the underside of the component.

3. The device as defined in claim 1 which is further characterized in that said clamp means are also formed from heat-conductive material.

4. The device as defined in claim 1 which is further characterized in that the heat-conductive material of said jaws comprises beryllium copper.

5. The device as defined in claim 1 wherein said clamp means comprise a pair of crossed arms fulcrummed together at one end thereof and secured to the respective jaws at their other end, and a spring reacting between said arms to urge said jaws toward each other.

6. The device as defined in claim 1 wherein said clamp means comprise a spring wire clamp having a pair of crossed arms and a coil portion connecting said arms together at one end so that the arms are urged together at their other end, said jaws being secured to said arms at said other end.
