ABSTRACT:
An extraction tool is provided for extracting an electronic circuit component. The tool includes an outer jaw assembly having a top plate and at least two outer legs coupled to the top plate defining an interior region therebetween. An inner jaw assembly is located in the interior region. The inner jaw assembly includes a bottom plate and at least two inner legs coupled to the bottom plate for engaging the chip. The apparatus also includes a slide collar slidably coupled to the outer and inner jaw assemblies. The collar is movable between a first position to permit the outer and inner legs to be inserted over the chip and a second position to lock the outer and inner legs in a predetermined engaging position relative to the chip. The apparatus further includes a mechanism for moving the inner jaw assembly relative to the outer jaw assembly when the collar in its second position to extract the chip. The length of the legs of the tool is selected to permit extraction of both large and small profile chips.
