Printer is to solder paste printing on the PCB equipment, it is one of the biggest impact on the process and quality equipment.
At present, the printer main points, semi-automatic printing machine and fully automatic printing machine.
Semi-automatic printer: simple operation, fast printing speed, simple structure, less controllable point defect is printing process parameters, the printing of the accuracy is not high, poor solder paste release, generally applies to more than 0603 (English) components, pin spacing greater than 1.27 mm in PCB printing process.
Fully automatic printing machine, printing of high accuracy, good effect in solder paste release, printing process, the more stable for dense spacing between components of printing, the disadvantage is that maintenance cost is high, the operators
