An exemplary film hole forming apparatus () includes a chemical etching system () and a driving system (). The driving system includes a transmission belt, which passes through the chemical etching system. A material of the transmission belt is polytetrafluoroethylene, polytetrafluoroethylene-containing material, polyvinylidene fluoride, metal, or metal-sandwiched composite. An exemplary method for forming film holes includes the following steps: providing a flexible printed circuit board () to be etched, with copper holes () pre-formed thereat and the copper holes exposing a base film () at corresponding positions; and transporting the flexible printed circuit board into a chemical etching system by a transmission belt to form film holes in the base film.

Apparatus for forming film hole

A method for manufacturing of flexible printed circuit boards is provided. The method includes the steps of: providing a tape substrate having an electrically insulating layer and an electrically conducting layer; forming a wiring pattern at the electrically conducting layer; attaching a back film on a surface of the tape substrate; and cutting the tape substrate to get a number of flexible printed circuit boards attached on the back film.
