A metallized substrate 2 with solder pad connection of a single-device chip 1 thereto is shown in cross-section in Fig. 1. The substrate interfaces with a ceramic metallized thermal interposer 3 which is soldered to the deformed pins 4. The metallized pads on the interposer together with thermal grease 5 provide an additional thermal path from the chip through the pins to the substrate and the cap 6. Fig. 2 illustrates a multi-chip embodiment with the cap removed.
