PCB thickness tester

The utility model relates to the technical field of PCB manufacturing, in particular to a PCB thickness tester. The device comprises a base, a fixed block, a sliding block, a positioning assembly, a first sensor, a test table and a rotating table, a rotating motor is arranged in the rotating table, an output shaft of the rotating motor is in driving connection with the test table, a second sensoris downwards arranged at the bottom of the test table, and a control device is arranged on one side of the fixed block; the positioning assembly, the first sensor, the rotating motor and the second sensor are all electrically connected with the control device; in practical application, a to-be-tested PCB is placed between the fixed block and the sliding block, the positioning assembly drives the sliding block to move to clamp the to-be-tested PCB, the test motor drives the top test bench to rotate to the position over the to-be-tested PCB, and the thickness of the PCB can be measured through the first sensor at the bo
