The utility model provides a printing steel mesh for two -sided makeup of PCB, the printing steel mesh is used for printing the tin cream, the printing steel mesh includes the steel mesh body, the symmetry is equipped with the reverse side half tone that is used for printing the positive front of PCB board half tone and is used for printing PCB board reverse side on the steel mesh body, the sculpture has a plurality of fronts to print mesh, every on the half tone of front the degree of depth of openly printing the mesh equals rather than the thickness that prints the tin cream of waiting thatcorresponds, on the reverse side half tone also the sculpture have a plurality of rear surface printing meshs, every the degree of depth of rear surface printing mesh equals rather than the thicknessthat prints the tin cream of waiting that corresponds. The utility model discloses only need just can realize processing the two -sided of PCB board with a production line to reduce line changing man-hour and technical staff's programming man -hour, and effectively reduced the probability that the bad product of quality produced.
