Pin Array Location Technique

      Disclosed is an inexpensive technique of locating individual
pins in a pin array to maintain pin to pin X, Y, Z relationships for
attachment to a printed wiring board.

      With location plate 1 assembled to printed wiring board 2,
individual pins 3 are loaded into plated through holes in printed
wiring board 2 resting in location plate indentations.  A pin
organizer 4 is assembled over the pins 3 which works in conjunction
with the location plate 1 to provide accurate X-Y location of the
pins 3.  The pins can now be captured by placing the assembly on an
arbor press base 8 and exerting force 9 to a rubber sheet, 5.  The
pressing operation takes place with hard rubber 6 and steel plate 7
barriers between the arbor of the press and the rubber sheet 5.  The
pins 3 are now locked into an X, Y & Z location.  After removing the
barriers and location plate 1, the pins 3 and rubber sheet 5 can now
be moved relative to printed wiring board 2 for subsequent
manufacturing operations, maintaining pin to pin X, Y, Z location.
Rubber pad 5 and pin organizer 4 are removable after pins 3 are
secured to the printed wiring board 2.
