Abstract
The present image sensor mounting system is particularly adapted to the mounting of a linear sensor array, of the type having a transparent window on a front surface and a thermal and electrically conductive back surface. The system provides superior electrical and thermal transfer characteristics. A heat sink having at least one flat surface is positioned to make thermal contact with the back surface of the image sensor. A multilayer circuit board having layers of conductive material separated by layers of insulating material and having an opening therethrough sufficient in size to accept the heat sink provides the system support. A metal plating extends from one surface of the board through the opening in the board to the opposite surface of the board with selected ones of the layers of conductive material making electrical contact with the metal plating. The heat sink is mounted in the multilayer circuit board opening in thermal and electrical contact with the metal plating. A layer of thermal and electrically conductive grease is layered between the at least one surface of the heat sink and the conductive back surface of the linear sensor array.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
