I was set up your machine one week ago. İt’s good working. Thank you for all.

—— Erdem

The machine operates well, we will purchase it again

—— Jon

The machine works very well, now we train all workers.

What are the factors affecting the stress of the PCB board?
Latest company news about What are the factors affecting the stress of the PCB board?

From the physics point of view, we can understand that when the material can not produce displacement under the action of external force, its geometry and size will change. This deformation is called strain. When the material is deformed, an equal-sized but opposite-direction reaction force is generated inside to resist the external force, and the concentration of the distribution internal force at one point is called stress. To put it simply, the internal force per unit area of a point in the section examined is called stress. Vertically perpendicular to the same section is called normal stress or normal stress, and tangent to the same section is called shear stress or shear stress.

 

We are an independent manufacturer of PCB separators,and we have great advantages and strengths for all aspects of the board. Regarding the stress of the cutting, it is also a problem that the design engineers of the router often think about. We usually say that the punching machine of the stamping machine is small in stress, and the laser dividing machine has no stress. What are the specific factors that affect the stress of the PCB boarding machine?

 

First of all,like some knife-type PCB separators,the PCB substrate is not moving during the cutting process, and the round knife slips, which can ensure that the electronic components of the substrate are not damaged by the movement, and is also a factor that affects the stress of the separator. In addition, the circular knife slip speed can be adjusted, the V-groove depth, the tool loss, the precise adjustment of the spacing between the upper circular knife and the lower straight knife, etc. all have an influence on the stress of the router.

 

Secondly, everyone uses the PCB cutting to minimize the stress, so that the PCB crack damage caused by the board can be avoided. Some sorting machines complete the sub-plate by crossing the V-groove. The cutting speed is controlled by the knob. The splitting stroke can be freely set and displayed by the LCD. These are also the factors affecting the stress of the PCB sub-board.
