For those who are new to SMT electronic placement, the Full-auto SMT Stencil Printer is just a bit confusing. Next, let’s introduce the working principle and usage skills of the Full-auto SMT Stencil Printer.
What is the working principle of Full-auto SMT Stencil Printer?
What are the tips for using Full-auto SMT Stencil Printer?
What are the precautions when using Full-auto SMT Stencil Printer?
First of all, we need to know that in the work of Full-auto SMT Stencil Printer, the requirements for Full-auto SMT Stencil Printer are very high, the solder paste release effect is good, the printing process is relatively stable, and it is suitable for the printing of fine-pitch components.
Secondly, when the Full-auto SMT Stencil Printer squeegee moves forward at a certain speed and angle, it exerts a certain pressure on the solder paste and pushes the solder paste to roll in front of the squeegee, and the Full-auto SMT Stencil Printer generates the solder paste into the net. The pressure required for the hole or leak;
On the one hand, the viscous friction force of the solder paste causes the solder paste to shear at the junction of the Full-auto SMT Stencil Printer squeegee and the stencil. The shear force reduces the viscosity of the solder paste and facilitates the smooth injection of the solder paste into the template. Openings or leaks. Full-auto SMT Stencil Printer squeegee speed, squeegee pressure, angle of squeegee and template, and viscosity of solder paste all have certain restrictions. Therefore, only by controlling these parameters correctly can the printing quality of solder paste be guaranteed;
On the other hand, when the Full-auto SMT Stencil Printer squeegee moves forward at a certain speed and angle, it generates a certain pressure on the solder paste and pushes the solder paste to roll in front of the squeegee, generating the pressure required to inject the solder paste into the mesh. , The viscous friction force of the solder paste causes the solder paste to shear at the junction of the squeegee and the stencil, and the shear force reduces the viscosity of the solder paste, thereby smoothly injecting into the mesh; when the Full-auto SMT Stencil Printer squeegee When leaving the template opening, the viscosity of the solder paste quickly returns to its original state.
When we are working, only when the solder paste rolls in front of the Full-auto SMT Stencil Printer squeegee, can the pressure to inject the solder paste into the opening be generated; the degree to which the solder paste fills the template opening determines the amount of solder paste, and the Full-auto SMT Stencil Printer releases The completeness of the mold determines the omission of the solder paste and the integrity of the solder paste pattern.
Therefore, introducing the working principle of Full-auto SMT Stencil Printer will be of great help to people who are new to the SMT industry. I hope everyone can remember carefully. If there is anything you don’t understand, you can contact ETA at any time. There will be professional Full-auto SMT Stencil Printer equipment technicians to explain to you!
