What brand of large-size solder paste printing machine is easy to use? Now there are many brands of printing presses, and the price differences of different brands are very different. Some people may think that machines are different. In fact, they are not. Each has its own advantages. There are good and bad. It's not all defined. The brand is easy to use. Automatic solder paste printing machine has obvious advantages, but it also has many disadvantages. There are many surface mount technology processes. One production and manufacturing needs to go through many processes. As long as one of them has a problem, the whole product will have defects. Therefore, the requirements for meritorious operation are very high, and important printing is easy to affect the quality of products.

Printing is a process based on hydrodynamics, which can be maintained repeatedly and repeatedly, and a certain amount of material (solder paste or adhesive) is coated on the surface of PCB. Generally speaking, printing is a very simple process. The PCB is kept at a certain distance or in full contact with the steel plate or wire mesh. Under the action of the scraper, the material will flow through the surface of the steel plate or wire mesh and fill the notch on it, so that the material will stick to the surface of the PCB, and then separate the PCB from the wire mesh or steel plate.

In the process of printing solder paste, the substrate is placed on the workbench, mechanically or vacuum clamped and positioned, aligned with positioning pin or vision, or screen or template is used for solder paste printing. In the automatic printing machine, the solder paste is distributed automatically. During the printing process, the printing scraper presses down on the template to make the bottom surface of the template contact the top surface of the circuit board. When the scraper passes through the entire length of the corroded graphic area, the solder paste is printed on the pad through the opening on the template or screen.
