Hand Tools Grounding for Manufacturing Sensitive Parts Assemblies

      Disclosed is a solution for making traditional manufacturing
tools ESD approved so that sensitive parts are protected from static
discharge.

      A variety of small hand tools are not grounded while operators
are using the tools for manual assembly in manufacturing.  These hand
tools and fixture handles are not built from ESD materials and cause
grounding discontinuity during manual assembly, such as driving
screws or inserting components.

      Grounding problems for small hand tools such as commercial
screw drivers with plastic handles, tools handles or knobs exist
during the manual assembly process in manufacturing.  These tools
have originally been designed to provide no electrical conductivity
between the operator and the parts.  In case of charge build-up from
the operator due to improper grounding of the operator (or the
parts), there is a great chance for static discharge via the part.

      The following are four possible techniques to protect sensitive
parts assembly from static damage:

1.  Kit package to fit existing tools (as shown in the figure)

2.  Plastic sleeve fitted to hand tool

3.  Spray coating

4.  Molded handles from ESD materials
