摘要
An information handling system (IHS) has a circuit board assembly with a dual-sided interposer substrate that is inserted between a baseboard and a processor integrated circuit having a second pattern of electrical contacts. The dual interposer substrate formed of a stack of printed circuit boards (PCBs) provides communication channels between a first coupling pad on the baseboard that has a first pattern of electrical contacts and a second coupling pad on top of the dual interposer substrate that provides the second pattern of electrical contacts. The second pattern receives another type of processor integrated circuit than a type supported by the first pattern. Stacked vias formed through the stack of PCBs electrically connect respective electrical contacts of the first and second coupling pads to form a corresponding communication channel. One or more grounded vias mitigate signal integrity (SI) anomalies on the communication channels.
