Context Before

Geometry loss describes the insertion loss incurred from abrupt structures of the PCB traces. Real PCB channels include many abrupt structures, such as vias and layer swaps.

Evidence

These are like bumps in a highway

Context After

, and signals could reflect backward and be interrupted increasing insertion loss.

② Atomic Claim

關於 PCB：這些結構可以類比為高速公路上的顛簸。
