Abstract
A microchip ( ) is mounted to a chip carrier ( ) in such a way as to avoid an earth fault between the chip ( ) and the carrier ( ). When mounting chips, the chip ( ) is placed on a chip carrier ( ) that includes an electrically and thermally conductive element ( ). The element includes a surface ( ) and a recess ( ) arranged relative to the surface. The microwave chip ( ) is arranged at the surface ( ) of the electrically and thermally conductive element ( ) by means of a fixing or bonding substance ( ), which is disposed at least partially in the recess ( ). When mounting the chip, the chip ( ) is positioned so that an earth plane ( ) of the microwave chip ( ) will lie level with the surface ( ) of the electrically and thermally conductive element ( ). The chip carrier ( ) is suitable for a chip mounting process and can be produced both readily and inexpensively.
