Abstract
The voltage at a node of an integrated circuit can be measured or controlled using a two-wire kelvin contact with spring-based probe pins by offsetting and tapering the lower end section of the spring-based probe pin. As a result, multiple spring-based probe pins can be connected to a single contact bump, such as a solder bump.
