A brush roller and its manufacturing method and brush roller mold is provided, the brush roller is manufactured by foaming a gaseous pore filler, while solving the problem of using a solid pore filler foaming method to manufacture the brush roller. In addition, the brush roller of the present invention has a plurality of fluid channels communicating between any adjacent two, and the plurality of fluid channels respectively extend to the surface of the brush roller to form pores to improve the fluid permeability of the brush roller, and in the brush roller manufacturing method of the present invention, after the PVA emulsified solution is cured, the compressive stress under the condition of the predetermined compression ratio can be formed to meet the expected brush roller, and it can be used to brush the circuit substrate. |
