FPC and use this FPC's smart mobile phone

The utility model provides a FPC and use this FPC's smart mobile phone, FPC includes first overburden, face of weld golden finger, substrate layer, copper line layer and the second overburden of stack setting in proper order, the width of copper line layer tip chap gradually forms non - face of weld golden finger, and the tin hole had all been seted up to face of weld golden finger and non - face of weld golden finger. FPC's terminal surface arrive respectively first overburden and second overburden apart from the imbalance, or FPC's terminal surface arrive respectively a plurality of face of weld golden fingers by the capped end apart from the imbalance, or FPC's terminal surface arrive respectively a plurality of face of weld golden fingers initial exposed position department apart from the imbalance, or FPC's terminal surface arrive respectively the width of a plurality of copper line layers tip initial chap position department apart from the imbalance, or FPC's terminal surface arrive respectively a plurality of non - face of weld golden fingers initial exposed position department apart from the imbalance, or FPC's terminal surface arrive respectively a plurality of cross the tin holes apart from the imbalance. Its have structural strength higher with be difficult for cracked advantage.
