VS1520A High precision screen printer

VS1520A High precision 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 menu.
• 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 storing 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.
