Figure 3BAs shown, the tilting device 220 is configured to drive the receiving board carrier 210 to tilt toward the stopper 212 at an angle θ2 when the receiving board carrier 210 receives a plurality of printed circuit boards P. In one example, the angle θ2 is between 60° and 80°, for example, 70°. In one example, the tilting device 220 is configured as a cylinder.
