Double Ended - Single Pin Straightener

      Disclosed is an implementation and a method for controlled
straightening of I/O pins in a closely spaced array, in a
semiconductor package.

      The I/O pins of an array must be within location tolerance to
permit module plug into connector system.  The pins are fragile.
Often the pin shank gets bent and requires straightening.

      The straightener consists of body (10) with two angular ends
(11).  The angular ends contain thru hole (12) with c sink (13).  In
operation, the thru hole receives bent pin shank (14) and permits
observing pin tip's location in respect to the adjacent array pins
(15).  During straightening, the pin shank is bent past the elastic
limit. After bending, the shank relaxes in the realigned position in
respect to the adjacent pins.

      The angular ends are fixed at approximately 120 degree angle
from the straightener's body.  This is to provide good visibility of
the adjacent pins.  The length of the angular end is slightly shorter
than the pin shank.  The thru hole diameter is somewhat larger than
the shank diameter.  The actual sizes of the body and ends depend on
the array density.
