Method of Fabricating Micro-mesh, Multi-usable Connectors

      Described is a method of fabricating micro-mesh
multi-usable connectors for use in micro-electronics applications.
The fabrication produces a connector that requires no extra external
holding devices and is designed for high density usage and is
repairable, restorable and has multiple uses.

      Typically, in order to achieve a component interconnection, the
most reliable way is to interconnect input/output (I/O) devices by
using self-aligning connector technology.  However, in high density
applications, such as the interconnection of micro-electronics, the
connectors are seldom repairable.

      The concept described herein provides a method for fabricating
a high density, multi-usable interconnection device.  The method
involves the utilization of VELCO*-type pad on pad technology
consisting of two parts: a fibrillar, woven part, and a hooked part.
The hooked, or male, part is electroplated with Pd or Pd-Ni dendrite.
Overplating of dendrite is not necessary in this case since small
branches of the dendrite would act as hooks.  The fibrillar, woven
structure, is obtained by the electroplating of conductive polymers,
such as polyacetylene or polyaniline.

      The fabrication method used in producing the micro-mesh, multi-
usable connector is performed as follows:
      1) High density Cu-polymer-type flex connector is fabricated
using conventional flex technology, either by using an...
