What stresses affect the PCB splitter

From the perspective of physics, we can understand that when the material cannot produce displacement under the action of external force, its geometry and size will change. This deformation is called strain.

When the material is deformed, the internal reaction force with equal size but opposite direction will be generated to resist the external force. The concentration of distributed internal force at a certain point is called stress. In short, the internal force per unit area at a certain point of the cross section under study is called stress, the normal of the cross section is called normal stress or normal stress, and the tangent of the cross section is called shear stress. Or shear stress.

First of all, like some knife fed PCB splitting machines, the PCB substrate does not move during the cutting process, and the round knife slips. This ensures that the electronic components of the substrate will not be damaged due to movement and is also a factor affecting the stress of the separator. In addition, it can adjust the sliding speed of the circular cutter, the depth of the V-groove, the loss of the cutter, and the accurate adjustment of the interval between the upper circular cutter and the lower straight cutter. Stress of separator.

Secondly, everyone uses the PCB splitter to minimize the stress, so as to avoid other damage caused by PCB rupture and separation process. Some plate splitters complete plate segmentation by crossing V-grooves. The cutting speed is controlled by the knob. The splitting stroke of the circuit board can be set freely, and it is equipped with LCD display. These are also the factors that affect the stress of PCB splitter.
