FLEXIBLE PRINTED CIRCUIT BOARD

A flexible printed circuit board according to the present invention comprises a first base sheet, a second base sheet, and a first protection sheet. The first base sheet comprises a first Teflon filmand a first circuit pattern disposed on the first Teflon film. The second base sheet comprises a second Teflon film and a second circuit pattern disposed on the second Teflon film, and is laminated onthe first base sheet. The first protection sheet covers the first base sheet. A portion of the first base sheet that is exposed to the first protection sheet is surface-modified. 根据本发明的柔性印刷电路板包括：第一基片、第二基片和第一保护片。第一基片包括第一特氟隆膜和布置在第一特氟隆膜上的第一电路图案。第二基片包括第二特氟隆膜和布置在第二特氟隆膜上的第二电路图案，并且第二基片被层压在第一基片上。第一保护片覆盖第一基片。第一基片的暴露于第一保护片的一部分被表面改性。
