Problem of the Slot Connector Model Extraction by De-embedding Methodology

Problem of de-embedding methodology for slot connector model extraction had been studied in this paper. De-embedding is effective for linear subtraction of trace length effect for connector model extraction. In slot connector, there is golden finger stub inside and it causes PCB material and contact point dependent reflection which are non-linear effect. This will cause gap between actual and simulated characteristics of slot connector and result in over-estimate of signal margin of system linkage.
