| titleOfInvention | Photosensitive dry film resist laminates and wiring boards |
| abstract | The invention belongs to the technical field of electronic materials. The invention discloses a photosensitive dry film resist laminate, which comprises: a support layer, including a first surface and a second surface; a resist layer, which is arranged on the first surface of the support layer, and the resist layer includes Resist; the first peel strength is between the first side and the resist layer, the second peel strength is between the second side and the resist layer, and the first peel strength is greater than the second peel strength; the support layer satisfies, After the second surface is peeled off from the resist layer, the residual amount of the resist on the second surface is less than or equal to 0.01 wt %. The invention adopts a photosensitive dry film resist laminate without a protective layer, which solves the quality problem of the resist layer caused by the defects of the protective layer, and can reduce the cost and the process of covering the protective layer; One side of the resist layer is modified, so that when the photosensitive dry film resist laminate is wound up, the resist layer will not be damaged by adhesion, and the resist layer can be easily released from the roll for lamination. |
