Packaging Technique for High Density Packaging using Flex Circuits in a Unique Manner

       This article describes a unique packaging concept due to
the structural assembly and lack of internal cabling.

      The idea utilizes flex circuit routed along and retained on a
(three) structural member of polycarbonate or similar material.
Three unique members are required to construct a multitude of
structural configurations.  The structural members are shown in Fig.
1. Each separate structural member is shown in Figs. 2 through 4.
The specific configuration shown is due to a packaging concept being
submitted.  This idea shows a unique method for establishing the
Octagonal Configuration.

      The concept is as follows:

      At the circuit containing connectors, etc., is routed and
restrained along a (one of three) structural member to the mating
surfaces male or female.  The mating surfaces could be the same
pattern or generic.  Two distinct surfaces would exist (male and
female).

      As the members are connected, the surface A is over center,
hence interference fit.  Using the male or Surface B, the flex
circuits are squeezed together making sufficient contact for sealing
and/or displacement.  As the surfaces are cammed together (rotated
into place) the cam or bump locks into the recession on B.

      To remove, Surface C is pulled into contact with Surface D and
the cam is removed from the recess.  As part I is pulled further, a
force n...
