|Used for:||PCB Screen Printing Stencil Machine|
|Our Main Market||Whole of the world|
emi-automatic printing machine: simple operation, fast printing speed, simple structure, the disadvantage is less control of printing process parameters, printing centering accuracy is not high, solder paste release is poor, generally applicable to 0603 (inch) above components, pins PCB printing process with a pitch greater than 1.27mm.
Semi-automatic solder paste printer
Fully automatic printing machine: high printing centering accuracy, good solder paste release effect, and stable printing process, suitable for printing with fine pitch components. The disadvantage is high maintenance cost and high requirements for the operator's knowledge level.
Solder paste and patch glue are all thixotropic and sticky. When the smt printer scraper moves forward at a certain speed and angle, it exerts a certain pressure on the solder paste, pushing the solder paste to roll before the scraper, and generating the pressure required to inject the solder paste into the mesh or the drain hole;
The sticky friction of the solder paste causes the solder paste to produce a shear at the intersection of the smc printing machine scraper and the mesh plate. The shear force reduces the viscosity of the solder paste and facilitates smooth injection of the solder paste into the template opening or the drain hole. Scraper speed, squeegee pressure, angle between the squeegee and the stencil, and the viscosity of the solder paste all have certain restrictions, so only by properly controlling these parameters can the solder paste quality be guaranteed.
SMT printing machine main technical indicators
The main technical specifications of the SMT press include the largest printing area, printing accuracy, repeatability, and printing speed.
1, the largest print area: according to the largest PCB size to determine.
2, printing accuracy: According to the PCB assembly density and pin spacing or the smallest ball distance device to determine the general requirements of ± 0.025mm.
3, repeatability: General requirements to achieve ± 0.01mm.
4, printing speed: according to production requirements.
