Summary:The embodiment of the invention provides a tin spraying thickness testing device. Comprising a base station for bearing the PCB, a pressing block and a rolling wheel, wherein the pressing block is used for being laminated on a tin spraying test position of the PCB on the base station, and a rolling surface is formed on the top surface of the pressing block; the rolling wheel is used for rolling on the rolling surface of the pressing block so that the pressure of the pressing block on the tin spraying test position of the PCB is uniformly distributed; the rolling surface and the bottom end face of the pressing block are parallel planes, and the mass of the pressing block and the mass of the rolling wheel are matched with the designed thickness of a tin layer to be tested in the tin spraying testing position. According to the embodiment of the invention, the pressing block and the rolling wheel are matched for use, the pressing block is firstly pressed on the tin spraying test position of the PCB, then the roll
