This paper describes a 320 Gb/s high-speed multichip ATM switching system for broadband ISDN. This system employs a copper-polyimide MCM with 4-layer copper-polyimide signal transmission layers and 15-layer ceramic power supply layers. The system uses 64 MCMs that are interconnected by 98-highway flexible printed circuit connector. Si-bipolar VLSI's are mounted on MCM's using the 150 μm very-thin pitch outer lead TAB technique. In addition, a high-performance heat-pipe air cooling technique is adopted. The system switches ATM cells up to 320 Gb/s throughput, which is applicable for future B-ISDN
