For flat cables, all the signal pairs are arranged side-by-side from one to each other. If a user would like to switch a signal from A1 of P1 end to A1 of P2 end, the user may need to utilize either a flexible printed circuit (FPC) or redesigned paddle card to solve this signal switching challenge. However, the FPC cost and the paddle card redesign cost are high compared to flat cable. Thus, a flat cable folding method for switching signal from one side to another side so as to easily switch a signal from A1 of P1 end to A1 of P2 end is disclosed herein.

A Folding Method of Flat Cable for Switching Signal 

For flat cables, all the signal pairs are arranged side‐by‐side from one to each other. If a user would like  to switch a signal from A1 of P1 end to A1 of P2 end, the user may need to utilize either a flexible  printed circuit (FPC) or redesigned paddle card to solve this signal switching challenge. However, the FPC  cost and the paddle card redesign cost are high compared to flat cable. Thus, a flat cable folding method  for switching signal from one side to another side so as to easily switch a signal from A1 of P1 end to A1  of P2 end is disclosed herein. 

For a miniSAS to miniSAS twinaxial cable assembly as shown below, A1 signal of P1 end can be  connected to A1 signal of P2 end following the folding method below (right to left steps).
