The invention provides a novel circuit forming method, and relates to the technical field of circuit forming. The new circuit forming method comprises the following steps: S1, pretreating a product substrate; S2, coating photoresist on the pre-treated substrate by using a coating roller to obtain a product with a photoresist pattern; S3, baking the product coated with the photoresist pattern to cure the photoresist; and S4, etching the baked product with the cured photoresist pattern to remove a copper foil which is not covered by the photoresist, and then, carrying out development to remove the photoresist on the surface of the product to obtain a required circuit pattern. According to the invention, the circuit board is manufactured by using a roller pattern coating method, so that the processes of exposure, development and the like are omitted, the original production process steps can be simplified, the labor and equipment costs are greatly reduced, adverse effects caused by manualoperation are avoided, the product quality can be ensured, and the production efficiency is improved.
