摘要：
A low impedance, low crosstalk disk drive suspension circuit has multiple traces carrying a first polarity of a differential signal, interleaved with multiple traces carrying the second polarity of a differential signal. Each pair of conductors consisting of a trace of the first polarity and a trace of the second polarity may cross over each other at multiple crossover points. The crossover connections may utilize a second layer of copper trace conductors over the first and main layer, or alternatively the crossover connections may utilize an isolated portion of the suspension substrate.
