AUREL Automation SPA.

DESCRIPTION 

The series VS screen-stencil printer uses highly advanced mechanical and electronical solutions to guarantee superior quality in fine-line and fine-pitch printing on Ceramic substrates, LTCC, PWB, WAFERS, GLASS, METAL etc.. The Automatic Vision System ensures resolutions better than 2 microns. All the machine's movements are motorized and programmed by a user friendly menu.

HEAD 

AUREL Model VS1520A
  AUREL Model VS1520A Screen-Stencil Printer

bullet

The new very intelligent head on high precision slides represents the latest state-of-the art design with motorized and programmable axis for fine teaching and adjustment of parameter.

bullet

High sensitive squeegee for fine-line printing, low pressure, constant angle, no vibrations.

bullet

DC motor driven head allows smooth movement and precise speed & stroke adjustments in both directions.

bullet

Configurable head in Single Squeegee, Double Squeegee, Squeegee and Flood Blade.

bullet

Motorized and programmable screen Z axis for screen height and for "slow snap-off function very important for fine line printing.

CONTROLS 
bullet

The machine is PC controlled and allows a great deal of flexibility on all functions. Only one colour monitor for camera images and menu.

bullet

Print and flood, alternating print, contact and off-contact print, double print and after print delay.

bullet

Machine diagnostic.

bullet

Machine hood & parts lifting and locking, setting up, and complete parameters controls & storage

WORK TABLE   VISION  
bullet

High precision motor alignment on the X-Y and Theta axis with 1 micron resolution for a perfect alignment between screen and substrate.

bullet

Substrate hold down by vacuum, pump included. Vacuum detector for substrate presence and chamber sensor.

bullet

Are available special fixture and chuck as porous plates for green tape as universal table for PWB's.

bullet

The vision camera is mounted on a X-rail, with the movement on this axis and the movement of the table in the Y-axis, the complete substrate area is covered. This allows to look at the fiducial marks, the vias or a pad wherever they are placed on the substrate.

bullet

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.

bullet

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

INFORMATION  
 
ACCLIMATIZATION SYSTEM   AUTOMATIC STENCIL CLEANING  

The machine con be equipped with the automatic control of temperature and humidity.  This con be very important for increased mechanical accuracy and to keep the pastes at the temperature level required for superior results.

A special cleaning system composed by a cleaning roller and a vacuum bar provides the solution for the stencil cleaning. The system is programmable as stroke, frequency, wet or dry and vacuum on/off.
