First, the printed circuit board graphic alignment
Through the printer camera, the optical positioning point (MARK point) of the substrate and the stencil on the workbench is centered, and then the X, Y, and Θ of the substrate and the stencil are finely adjusted to make the substrate pad pattern and the stencil opening. The graphics are completely coincident.

Second, the angle of the scraper and the circuit board during printing
The smaller the angle between the scraper and the stencil, the greater the downward pressure, the easier it is to inject the solder paste into the mesh, but it is also easy to squeeze the solder paste onto the underside of the stencil, causing the solder paste to stick. Generally 45~60 °. Currently, most automatic and semi-automatic printing presses use 60°.

Third, the amount of solder paste applied to the smt solder paste printing machine (rolling diameter of solder paste)
1. The rolling diameter of solder paste is suitable for ≈h≈10~15mm. 2. The rolling diameter ∮h is too small to cause solder paste to be printed and the amount of tin is small. 3. The rolling diameter ∮h is too large, too much solder paste is in When the printing speed is constant, it is easy to cause the solder paste to fail to form a rolling motion, the solder paste cannot be cleaned, resulting in poor printing release, poor solder paste after printing, etc.; and excessive solder paste is exposed to the air for a long time. The quality of the solder paste is unfavorable. 4. During the production, the operator visually inspects the amount of solder paste on the stencil every half hour, and moves the solder paste outside the squeegee stroke on the stencil to the stencil every half hour. The solder paste is evenly distributed within the stroke of the blade, but it cannot be shoveled into the opening of the stencil.

Fourth, the pressure of the scraper when the smt solder paste printing machine works
The blade pressure is also an important factor affecting the printing quality. The blade pressure actually refers to the depth of the blade falling, the pressure is too small, the blade does not adhere to the surface of the steel mesh, so it is equivalent to increase the printing thickness. In addition, the pressure is too small, the surface of the steel mesh will remain. A layer of solder paste can easily cause printing defects such as printing and bonding (bridge).

?Fifth, the printing speed of smt solder paste printing machine
1. Since the speed of the scraper is inversely proportional to the viscosity of the solder paste, the speed is slower when there is a narrow pitch. The speed is too fast, the time for the scraper to pass through the opening of the steel mesh is relatively short, and the solder paste cannot fully penetrate into the opening. In the middle, it is easy to cause printing defects such as insufficient solder paste or missing printing.
?2. There is a certain relationship between the printing speed and the blade pressure. The descending speed is equivalent to increasing the pressure. Appropriately reducing the pressure can improve the printing speed.
3. The ideal scraper speed and pressure should be just scraping the solder paste from the surface of the steel mesh.

?Six, smt solder paste printing machine working gap
The printing gap is the distance between the steel mesh and the PCB, which is related to the retention of the solder paste on the PCB after printing.

7. Separation speed of stencil and PCB when smt solder paste printing machine works
After the solder paste is printed, the instantaneous speed of the steel mesh leaving the PCB is the separation speed, which is the parameter related to the printing quality. It is the most important in the dense pitch and high-density printing. The advanced printing machine has its steel mesh leaving the solder paste pattern. 1 (or more) a small dwell process, ie multi-stage demolding, which guarantees the best printing.

When the separation speed is too large, the sticking force of the solder paste is reduced, and the cohesive force of the solder paste and the pad is small, so that some solder paste adheres to the bottom surface of the steel mesh and the wall of the opening, causing printing defects such as less printing and tin collapse. The separation speed is slowed down. When the solder paste has a large viscosity and a large cohesive force, the solder paste is easily separated from the stencil opening wall and the printing state is good.

Eight, smt solder paste printing machine cleaning mode and cleaning frequency
Cleaning the bottom of the steel mesh is also a factor to ensure the quality of the printing. The cleaning mode and cleaning frequency should be determined according to the conditions of solder paste, stencil material, thickness and opening size. (Set dry cleaning, wet washing, reciprocating, wiping speed, etc.)
