Abstract

An interconnect system is designed to reduce the number of components in an interconnect system and increase the interconnect reliability. The system is used to connect two or more printed circuit boards in parallel. The system uses solder as the conductive interface between the interconnect pin and the plated hole in the printed circuit board.

Multiple Electronic Board Interconnect System

       An interconnect system is designed to reduce the number
of components in an interconnect system and increase the interconnect
reliability.  The system is used to connect two or more printed
circuit boards in parallel.  The system uses solder as the conductive
interface between the interconnect pin and the plated hole in the
printed circuit board.

      As shown in the figure, a printed circuit board 1 is spaced at
a desired distance from printed circuit board 2 and printed circuit
board 3 by the assembly of round or square pins 4.  These pins are
held in printed circuit board 1 by means of an interference fit.  The
pins are then soldered to board 1 using an automated solder reflow
system. Printed circuit boards 2 and 3 are soldered to opposite ends
of the connector pins.  The holes in boards 2 and 3 do not require
the same interference fit as board 1 because the pins are previously
soldered to board 1.

      The interconnect pins are used to make the electrical
connection between the printed circuit boards and also provide the
mechanical strength to maintain the proper spacing between the
printed circuit boards.

      This interconnect system can use various-length pins 5 which
provide a connection between selected printed circuit boards.  These
pins can be located on a very close centerline distance from each
other to obtain a very high interconnect pin count.  Alternate design
