DIMA is introducing a new breed of semi-automatic screen printers belonging to the Hybrid family of production equipment for SMD printed circuit board assembly. The hart of the machine is based on a rigid casting where the motor driven printing head is guided over the frame by linear bearings. All parameters like printing speed, squeegee pressure, lift-off speed, printing stroke and maintenance parameters can be programmed from the windows based user interface. The circuit board can be set up using the highly flexible magnetic locator pins, board supports and vacuum units. Making a test print on a Mylar foil allows you to align the board under the printed pattern so that your production run starts with a perfect print. The printer comes standard with off-line software to prepare production on networked computers at another location. The TFT monitor gives a clear view on the process and the board alignment.

The DIMA Software The printer is equipped with the unique DIMA- software ® user interface teaching the correct position of the board to the software is done by using the self learn modus of the vision system (screen 1). Once the system knows the correct position of the board it will alarm the operator when the board position is not correct. At the same time the software will give the operator instructions about the direction that the PCB has to be moved (screen 2). The acceptance level of the vision system can be programmed between 1 and 100 Micron. As soon as the position of the board is within the given tolerance the navigation cross window changes from red into white and the start buttons become activated. Parameters for switching the vacuum to hold the PCB is controlled by software. All printing parameters can be set by the software. User management software in combination with access passwords ensures full security. An unlimited number of programmers with different process parameters can be stored. For off-line product file editing the Printer can be connected to the company network.
