Abstract: Provided are a flexible circuit mother board and a detection method. The flexible circuit mother board includes flexible circuit daughter boards, at least one detection terminal group and external pad groups corresponding to the flexible circuit daughter boards in one-to-one correspondence. Each flexible circuit daughter board has a bonding pad area adjacent to a corresponding one of the plurality of external pad groups. Each detection terminal group detects at least one flexible circuit daughter board, and each of the at least one detection terminal group comprises a plurality of detection terminals. Each flexible circuit daughter board includes a plurality of capacitors including a first electrode plate and a second electrode plate. Each of the first electrode plate and the second electrode plate is electrically connected to one detection terminal.

Abstract: Provided is an FPC, including a first row of gold fingers and a second row of gold fingers disposed on a same layer, and multiple first connection lines. The first row of gold fingers includes multiple first gold fingers extending in a first direction and arranged in a second direction. The second row of gold fingers includes multiple second gold fingers extending in the first direction and arranged in the second direction. The multiple first connection lines are disposed in a different layer from the second row of gold fingers, electrically connected to the multiple first gold fingers, and insulated from the multiple second gold fingers and extend to an area where the second row of gold fingers is located. The first connection line includes a first wire and a second wire. The first wire includes a first portion, a second portion and a third portion connected in sequence.
