3.7 HOME position and registration hole system
The HOME position must be on the machine's axis of symmetry (registration hole system) to
ensure correct alignment of a double-sided board.
Double-sided boards are rotated about this axis of symmetry.
Inaccuracies in the HOME position result in misalignment when double-sided boards are
rotated during the machining process.
The HOME position is contained on the configuration diskette supplied as standard. With the
BoardMaster program and configuration diskette correctly installed, the HOME position
corresponds to the setting for the x/y coordinates as measured during the acceptance test.
Please note:
The registration hole system can only be guaranteed to be parallel for the
current position of the registration hole strips.
The front registration hole slide must be pushed against the pin in the
reference groove (reference point).
An additional hole must be drilled in the rear registration hole strip for
each format if board material of different sizes is used.
To do this, move from the HOME position towards the rear registration
hole strip.
Now move the rear registration hole strip to the required position.
Once the necessary tool change has been made automatically (2.95 mm
drill with a different colour spacer ring must be positioned in the tool
magazine by now), another hole is drilled in the slide.
The position of the slide for the various holes should be recorded or
marked on the circuit board plotter.
This guarantees parallelism for different formats.
You will need to perform a test run on the machine to check the coordinates
of the H
OME
position on new machines and after transporting the system.
The individual steps are described in the next section, "Checking and correcting the HOME
position".
No further action is required if the preset coordinates are correct. If this is not the case, the
corrected coordinates will have to be entered in BoardMaster.
See the section entitled "Programming the HOME position in BoardMaster".
