Printed-circuit board
A printed-circuit board includes: a film-shaped thermoplastic base member having plasticity; a pattern fuse formed from a metal foil layer provided on a principal surface of the base member; a cover member covering at least part of the pattern fuse from an opposite side of the base member; and a first heat-resistant protection film provided on a region overlapping with at least part of the pattern fuse and covering the pattern fuse from a cover member side.
1. A printed-circuit board comprising:
a film-shaped thermoplastic base member having plasticity;
a pattern fuse formed from a metal foil layer provided on a principal surface of the base member;
a cover member covering at least part of the pattern fuse from an opposite side of the base member;
a first heat-resistant protection film provided on a region overlapping with at least part of the pattern fuse and covering the pattern fuse from a cover member side; and
a second heat-resistant protection film provided on a region overlapping with at least part of the pattern fuse and covering the pattern fuse from a base member side.
2. The printed-circuit board according to claim 1 , wherein
the cover member contains thermoplastic resin.
3. The printed-circuit board according to claim 1 , wherein
the base member contains thermoplastic resin.
4. The printed-circuit board according to claim 1 , wherein
the base member and the second heat-resistant protection film are bonded to each other with a thermoplastic adhesive for the second heat-resistant protection film.
5. The printed-circuit board according to claim 4 , wherein
the adhesive for the second heat-resistant protection film has an opening which opens at a region overlapping with part of the pattern fuse.
6. The printed-circuit board according to claim 1 , wherein
materials of the base member and the cover member are an identical type of material.
7. A printed-circuit board comprising:
a film-shaped thermoplastic base member having plasticity;
