Abstract
An FPC assembly (10) includes a circuit unit (12) with two different pitch arrangement connectors (14, 16) at two opposite ends. The circuit unit (12) includes a signal FPC (18) and a grounding FPC (20). A buffer layer (22) with adhesives on two opposite surfaces (24, 26) is sandwiched between the signal FPC (18) and the grounding FPC (20), and thus the signal FPC (18), the buffer layer (22) and the grounding FPC (20) are adhesively fastened with one another as one circuit unit (12). The signal FPC (18), the buffer layer (22) and the grounding FPC (20) respectively include contact tail holes (34, 35) at two opposite ends for receivable engagement with the corresponding contact tails (36, 37) of the connectors (14, 16).
