Automatic screen printer achieves high-accuracy

With high-speed printing within six seconds plus printing time, Juki Automation Systems has introduced the RP-1 Automatic Screen Printer. Achieving high-accuracy positioning of ±10μm, the RP-1 high-speed and high-precision printer is equipped with the Motion Screen feature that automatically corrects the printing position by moving the screen.

Additionally, optional “Automatic Solder Dispenser” and “High-speed Cleaning” functions are now available, enabling higher-speed printing, stable repetitive printing accuracy and reduction of environmental load.

“Automatic Solder Dispenser” is a function to keep the dispensed solder amount optimal. This dispenser automatically supplies solders by measuring the solder’s rolling diameter with a sensor and adjusting the volume accordingly. Therefore, the printing pressure on the PWB is kept stable at all times, preventing solder paste from bleeding or blurring. Also, a complete consumption of solder paste significantly reduces discarded solders.

The “High-Speed Cleaning” function automates the mask cleaning procedure, which used to be done manually. With its specially-shaped blade scraping solder leftovers, it reduces operation time of moving the cleaning unit. Higher cleaning frequency leads to improved printing accuracy. Also, a required cleansing paper is only 8mm, making this procedure extremely economical.
