Multichip modules for automotive applications
A. Simsek, Wilhard Strohschein, H. Reichl · 1999
A 16-Bit Microcontroller Multichip Module (MCM) is described which is EMC compliant and suitable for automotive and industrial applications. The MCM was developed in laminate technology with wire-bond chip interconnection. A custom-specific package was realised in reflow-soldered edge clip gullwings in standard QFP-outline. The EMC-constraints were easily solved by shielding the MCM with its own ground-plane. Reliability and cost-targets are met by the widely-structured, low-cost 4 layer laminate technology. It can be used in a wide range of industrial and automotive applications like sensor interfaces, equipment and engine control, intelligent CAN-Bus components, controller for power switches even at high environmental requirements. This paper will discuss different MCM technologies, applicable for the realization of microcontroller modules.
