Single/ Dual Beam Switchback Zero Insertion Force

       Disclosed is an electrical contact for making high
performance interconnections to electronic packages with Zero
Insertion Force (ZIF) of the electronic package into the package
containing the described contacts.

      Test equipment used for the verification of electronic packages
generally calls for the use of ZIF contacts to make the interconnect
between the test station and the package. As technology advances,
these connectors need to provide high performance and reliable
interconnects.

      The contact design described in this article provides a dual-
point contact to a cylindrical mating pin which occurs in a single
motion for these two points of contact.  The dual switchback beams
provide an extension in beam length over a short vertical distance
which provides sufficient elasticity to conform to the mating pin
size and position. The single base beam interfaces with the actuation
mechanism and provides substantially greater spring force in the
direction of the mating cylindrical contact.

      In the figure, items 101 and 109 show a dual-contact and a
quad-contact version connector, respectively.  Item 101 points to the
Single Beam section of this contact.  This portion of the contact
provides the elasticity for conforming to the mating cylindrical
contact.  The surface area, item 103, is where the actual mating
occurs.  Upon actuation, a wiping occurs across this surface.  Item
