V1 for laser direct imaging LDI

Automation for direct imaging V1

V1 automation for LDI

The V1-LDI Loader/ Unloader was designed to load direct imaging machines reducing to drastically the human intervention. This machine was designed to serve medium and prototype PCB shops with a big mix of jobs.  

The V1 – LDI Loader has the capability to load and unload inner and out layers with dry film, roller clean the top surface and  them and lay them on the DI table to be exposed.  The Loader has a full integration with the DI in order to know when the board has been exposed, when it need to be flipped and when to be removed from the table.  The full protocol integration with the DI is designed to generate a job list with as many as required different jobs.

Equipped with 2 L rack Stations, first one used to load non exposed panels and second one as a buffer station.  A full integrated cleaning device guarantees the panel is roller cleaned before laid on the DI table.  The machine comes equipped with an automatic turning device in order to expose both sides (A and B) without human intervention.

The V1- LDI Loader can be installed to any Direct Imagine machine available in the market.

The design of our LOADER/UNLOADER LDI-V1 grants a full-time operation of the Direct Imagine machine. This automation will be able to cover with full guaranties the loading and unloading of the Direct Imagine machine even with single panels jobs. This mean the automation and the Direct imagine are fully connected and able to change jobs without the need of  manual intervention.

Main advantages of the TECHNO SYSTEM LDI-V1  in front of competitors are:

  • Reduced foot print. Techno System only requires 1,1m at the side of the DI
  • High speed performance, less than 19.5 seconds per cycle including roller cleaning, flipping alignment and placing in DI table
  • No need to identify the size of the panel. This makes preparation of the loader very easy requiring very short preparation time.
  • Cero position of the panel can be in any corner of the panel, selected by customer.
  • Automatic alignment of 100% of the panels before loading  into the DI table. This assures perfect alignment on the DI table and no alignment failures.

    • CCD camera installed in the system combined with  our 6 Axis robotic arm are capable to align on the fly all panels with  no time consuming. Alignment includes X, Y and rotation of the panel.
    • For Out layer loading we can do hole registration on each panel, which will guaranty that holes are place precisely in the target recognition area of the DI . If panels are not perfectly cut or have the minimum twist, DI can easily miss the holes and abort the exposure due to hole registration area.
    • Techno System , installs a Fanuc high end robotic arm which grants extremely high reliability of the system.
    • For batch change identification tree ways of operation are possible.
      1. Plastic sheets to identify the change of the batch.
      2. Last panel of the batch displaced 1 ,5 cm
      3. By counting panels.
    • By using the tilted L Rack, we can operate a with thin core down to 50 microns, at high speed.
    • Techno System Install air knifes on top and bottom L Rack for additional loading securities.
    • High speed Turning device for side B printing Prepared for 50 micron up to 3,2mm.
    • Roller cleaner device integrated on  the loader.
    • Machine equipped with 2 L racks on over the other with simple and comfortable access.
    • Optionally the loader can work with extra thin PI material of 25 micron. L racks in horizontal position instead of semi vertical. (Optional )
    • Full lateral access to the DI for maintenance. No need to move that machine to access the DI side for maintenance.


A or B of the batch the robot will signal the LDI to change the batch file and print accordingly. Batch recognition is made by manually offsetting the last panel (during loading into the rack) within each batch 10-15 mm to the right of the other panels. Alternatively, a separator sheet can be placed between batches. The Loader will provide a signal to the LDI confirming the last panel in a Batch. In the case this does not correspond to the batch quantity data programmed into the LDI the process will stop the Loading devise and sound an alarm.
