Use of Insulating Stanchions for the Prevention of Electrical Shorts

      A family of insulating stanchions for inhibition of electrical
shorts as well as enhancement of mechanical stability on all
electrical components with exposed conductive material is provided.
Sample drawings for the design of a TO-220 and TO-18 package are
shown in the Figure.

      It is important that the insulating stanchion be constructed in
such a manner as to allow for component wash during the manufacturing
process yet restrict the flow of foreign material around any exposed
conductors during device operation.

      Stanchions could be designed for all commercially available
component packages, including SIPs, DIPs, and SOICs.  In some cases,
a top mount clip-on approach may be required to prevent assembly
problems during the board process.  In those cases, the stanchion
would provide electrical insulation only and no added mechanical
support.  Use of stanchions in general has been shown to reduce
manufacturing fallout in cases where mechanical integrity and form
factor of the component is critical.
