Abstract:
A method of making a wiring board having a low CTE isolator incorporated in a resin core is characterized by the provision of an adhesive substantially coplanar with the metallized isolator and the metal layers on two opposite sides of the resin core at smoothed lapped top and bottom surfaces so that a metal bridge can be deposited on the adhesive at the smoothed lapped bottom surface and connect the metallized isolator with a surrounding heat spreader on the bottom surface of the resin core. In the method, routing circuitries are also deposited on the adhesive at the smoothed lapped top surface so as to provide electrical connections between contact pads on the isolator and terminal pads on the resin core.

Claim (Index 1):
A method of making a thermally enhanced wiring board having isolator incorporated therein, comprising steps of:\n providing an isolator having opposite planar first and second sides, wherein the isolator is made of a thermally conductive and electrically insulating material; depositing first and second metal films respectively on the first and second sides of the isolator to provide a metallized isolator; providing a laminate substrate that includes a resin core, first and second metal layers respectively disposed on opposite first and second sides of the resin core, and an aperture formed in the laminate substrate, wherein the first and second metal layers each have a planar surface; inserting the metallized isolator into the aperture of the laminate substrate with the first metal film on the isolator and the first metal layer of the laminate substrate facing towards the same direction, and then dispensing an adhesive into a gap between the metallized isolator and the laminate substrate within the aperture to adhere sidewalls of the metallized isolator to sidewalls of the aperture; removing an excess portion of the adhesive, thereby the adhesive having a first surface substantially coplanar with the first metal film on the isolator and the first metal layer of the laminate substrate, and an opposite second surface substantially coplanar with the second metal film on the isolator and the second metal layer of the laminate substrate; depositing a continuous thermally conductive joint layer on the first surface of the adhesive, the first metal film and the first metal layer, to connect the first metal film on the isolator to the first metal layer on the resin core; and forming contact pads on the second side of the isolator, terminal pads on the second side on the resin core, and routing circuitries that electrically connect the contact pads to the terminal pads.
