Abstract
Electrical connection between a measurement instrument and a semiconductor device having internal elements sealed in a non-conductive package, is established by way of leads which protrude out of the semiconductor device, when it is mounted on an antistatic socket apparatus. The socket apparatus has a bearer which is made of a non-conductive material that has a resistance selected to permit diffusion of static charges but which otherwise maintains adequate electrical insulation properties. Protrusions on a mounting surface of the socket support the package through contact surfaces which have a total area smaller than that of the mounting surface of the bearer and which reduce the static charge generating frictional contact between the package and the socket apparatus.
