Abstract

The invention disclsoes an electronic system with a composite substrate. The electronic system comprises a circuit board mounted on a metal frame. High heat generated electronic components are adaptedto mount on the lead frame and relatively low heat generated electronic components are adapted to mount on the circuit board. Metal lines are used for electrical coupling between the circuitry of theIC chip and the circuit board. After the whole electronic system is packed with rubber, the bottom of the metal frame is exposed for dissipate heat. An electronic system with the composite substrategains both advantages-good circuitry arrangement capability from the circuit board and good heat distribution from the lead frame.
