ABSTRACT A motor driven apparatus (1) to efficiently and reliably straighten the leads of a pin grid array (PGA 140) so that the leads are aligned parallel with one another and perpendicular to the flat PEA body. The apparatus includes a nest of parallel knife blades (90) which is mounted for linear travel so as to be either introduced to or retracted from the grid of PEA leads The nest of knife blades is carried by an oscillator assembly (32) which is adapted to automatically oscillate (i.e. pivot) the blades between respective rows of PEA leads. When the nest of knife blades is introduced to the grid of PEA leads, the back-and-forth oscillations of the knife blades will cause the blades to engage and straighten any bent leads. The PEA is carried by a rotatable table assembly (10). When the nest of knife blades is retracted from the grid of PEA leads, the table assembly may be automatically rotated (e.g. by 90 degrees) so that the grid of leads is oriented for repeated engagement by the nest of knife blades, whereby bent leads may be reliably straightened, regardless of the angle at which such leads are bent.
