Abstract
An isolation resistor is incorporated into the plunger of a probe tip spring pin by, for example, doping a ceramic that is used to form the plunger, or forming the plunger of first and second electrically coupled materials, at least a first of which has a resistivity sufficient to serve as an isolation resistor. Alternately, an isolation resistor is embedded in a printed circuit board trace that is used to couple either an upper or lower blind plated hole to a via. A probe tip spring pin is then inserted into the upper blind plated hole.
