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.

DETAILS

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

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

INTELLIGENT DOUBLE SQUEEGEE HEAD

AUTOMATIC VISION SYSTEM

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
