MULTI-STAIR AND MULTI-WIRE SUBCARD OF CONNECTOR

摘要

The wide width copper memberes for grounding are deposited between narrow width copper members in patterns for signal transmission to absorb the crosstalking between the signal copper lines. The auxiliary card comprises pattern layers an which ground patterns are formed between the signal patterns, epoxy laminate layers to isolate the pattern layes, and ground pattern connector for connecting ground patterns of each pattern layer through holes.
