TecnoCut PlateChanger Set Up /1

• HARDWARE (complete)
• both glued / not glued emulsion setup
• cabling of the interface PlateChanger - LNGS
  level adapter board NI7344
• cabling and pneumatic connection of the
  air/vacuum device for the glass window
• cabling and pneumatic connection of the oil
  dispenser
• oil dispenser mechanical support (new design by
  LNGS)

• additional tools
• frame press to help vacuum on the glass window
  (new design by LNGS)
• compressed air nozzle to help emulsion detachment
  from the glass window (electrovalve, cabling,
  pneumatic connection and mechanical support)
• compressed air to help emulsion detachment from
  the cleaning tool surface (electrovalve, cabling,
  pneumatic connection)
• proximity switch to inhibit microscope movements
  when platechanger arm is over the glass window
  (switch, cabling, mechanical support)

TecnoCut PlateChanger Set Up /2

• FIRMWARE (complete - version 4)
• platechanger state can be read outside for
  synchronization with the software
• emulsion counter is removed
• an additional input signal is provided to manage
  the (un)load of the last emulsion plate
• provide compressed air to help the emulsion
  detachment from the cleaning tool surface
• provide vacuum when the arm put the emulsion on
  the cleaning tool surface

• SOFTWARE (minimal software available)
• Basic Digital IO interface complete (through new
  module FlexStage5)
• Scanning process integrated with oil distribution
  (customized VertigoScan7)
• Fiducial Mark Finding integrated with oil
  distribution (new FlexMapX)
• macros to manage the Load/Unload/OilDispense jobs
  (new module TCPlateChanger)
• Synchronization with the platechanger to improve
  reliability at startup, after failures, (manage
  problems like load command received when
  unload is expected, restart after software or
  platechanger crashes, )

TecnoCut PlateChanger Set Up /3

• TEST AND MEASURE
• Full brick load/unload skipping oil (mark
  finding, area scanning, ) ok (glued/not
  glued)
• Scanback and totalscan of some bricks (oil
  distribution included) (after tuning of mark
  finding and platechanger alignment tools)
• not glued too lateral mark finding failures
  (focus problems outside the vacuum channel due to
  oil)
• glued ok but frequent cleaning of separators,
  suckers, surfaces,

Conclusions
The hardware and firmware set up can be
considered closed for what concerns the requested
functionalities. Mark finding improvements
useful for not glued emulsions (in progress)
manage and/or trace the lateral mark clone
problem focusing before lateral mark
search Now, standard measures are necessary to
verify the reliability and stability of the
system.
