High precision screen printer – VS1520A

VS1520A Aurel Fine line screen printer

Aurel VS1520A uses highly advanced mechanical and electronic solution to guarantee superior quality in fine-line printing for multilayer hybrids circuits. The automatic vision system ensures resolution better than 2 microns.

All the machine’s movements are motorized and programmable by S/W through an user friendly menù.

All the print parameters (pressure, speed, down stop, print gap) are programmable and storable in work recipes to grant the minimum setup time.

Applications

Aurel VS1520A is a free standing high precision screen printer with cabinet and security cover that can print area up to 400 x 300 mm, assuring uniform deposition from corner to corner.

Some applications for electronic and general industrial purposes are:

  • Thick film and polymer pastes
  • Multilayer Hybrids
  • Solder paste for SMT
  • Glues, adhesives, resins
  • Through holes metallization
  • Solder resist
  • Flexible foils, PET film, paper
  • Solar cells, semiconductors, glass, quartz
  • Polymeric pastes LTCC and Via Filling
  • Silver Sinter
  • Heaters on metal substrates

Control systems

  • The machine is PC controlled and allows a great deal of flexibility on all functions Windows © Operating System
  • Wide Touch screen monitor with user friendly interface
  • Print and flood, alternating print and after print delay
  • Programmable print parameters (printing stroke, pressure, print gap & down stop)
  • Machine diagnostic
  • Machine hood & lifting and locking safety switches
  • Work recipes and data logging

Head

  • The intelligent head on high precision slides represents the latest state-of-the-art design with motorized and programmable axes for fine teaching and adjustment of parameters.
  • High sensitive squeegee for fine-line printing, low pressure, constant angle, no vibration.
  • DC motor driven head allows smooth movement and precise speed & stroke adjustment in both directions.
  • Configurable head, single squeegee, double squeegee, squeegee and flood blade.
  • Motorized and programmable screen Z axis for screen height and slow snap-off function – very important for fine line printing.

Vision

The vision camera is mounted on a X axis with linear motor. The movement on this axis and the movement of the table in the Y-axis cover the complete substrate area.

This allows to look at the fiducial marks, the vias or a pad wherever they are placed on the substrate.

A special optic and IR lighting system is integrated in the TV-camera assembly. Room lighting or PCB colours no longer influence the reliability of the vision system.

The vision system is PC based with a very advanced software for easy teaching and automatic adjustment of all parameters and values.

Work table

  • High precision fast linear motors. Alignment on the X-Y and Theta axes between screen and substrate.
  • Substrate hold down by vacuum, Venturi ejector included. Vacuum detector for substrate presence and chamber sensor.
  • Easily exchange different fixtures according to the substrate size: acrylic or aluminium nest, micro porous stone, multi-holes chuck, universal table for PCBs.

Other options

  • Paste Reload Dispenser
  • PHM, Programmable Holes Metallization and VIA filling
  • Substrate cleaning via roller contact, air knife, ionizer bar
  • Led UV LAMP
  • Bar code reader
  • Pneumatic screen locking
  • PPI, Post Print Inspection
  • Climatization system
  • Automatic stencil cleaning (only for stencil)
