Abstract
A burr-suppressing copper foils are described. In an embodiment, the burr suppressing copper foil includes a poly-based film having an adhesive on a first side and an adhesive on a second side. A copper foil contacts the adhesive at the first side of the poly-based film to removably couple the poly-based film to the copper foil. A metallic burr suppressor contacts the adhesive on the second side to removably couple the poly-based film to the metallic burr suppressor.

A burr-suppressing copper foil comprising:
- a poly-based film having an adhesive on a first side and an adhesive on a second side;
- a copper foil contacting the adhesive at the first side of the poly-based film to removably couple the poly-based film to the copper foil;
- and
- a metallic burr suppressor contacting the adhesive on the second side to removably couple the poly-based film to the metallic burr suppressor.
A method of manufacturing a burr-suppressing copper foil, the method comprising:
- providing a copper foil, a metallic burr suppressor, and a poly-based film, the poly-based film having an adhesive applied to opposing sides of the poly-based film;
- attaching the copper foil to the poly-based film at a first side of the poly-based film using the adhesive;
- and
- attaching the metallic burr suppressor at a second side of the poly-based film using the adhesive.
A method for manufacturing a printed circuit board (PCB), the method comprising:
- constructing a book having a burr-suppressing copper foil on at least one exterior sides of the book, the burr-suppressing copper foil comprising a poly-based film having an adhesive applied at opposing sides, a copper foil coupled to the poly-based film on a first side of the poly-based film and a metallic burr suppressor coupled to the poly-based film on a second side of the poly-based film, the metallic burr suppressor being an outer layer of the book;
- applying a lamination cycle to the book using a laminating press to cure the book;
- and
- after the lamination cycle, drilling the laminated book.
