ABSTRACT:
An electrical feed through for use in a high temperature oven such as the oven in a gas chromatograph. The feed through includes printed circuit boards which are maintained in compression to prevent the boards from physically separating at the elevated temperatures used in the oven. The structure that provides the compression also does not allow any flexure, torsional or longitudinal stress on the boards. The boards include an enhanced connector pad which is made from a continuous annular copper ring which is connected to all of the conductive layers of the board.
