Each need to carry out SMT SMD processing of the circuit board is different, so its placement procedures will be different, then in the patch processing before the patch staff is how to edit the patch machine? Next we come together to understand it.
The key components of SMT SMD programming:
1, component layout information: in short, this information describes the specific location, rotation angle, and model number of each component that needs to be placed on the PCB board. This information usually includes the component model, bit number, X-axis and Y-axis coordinate values, as well as the expected placement angle. The origin of the coordinates is usually set in the lower left corner of the PCB board.
2, benchmark identification parameters: benchmark data covers the location of the reference point, color, brightness and search range. Before the start of the placement operation, the camera on the placement machine will first look for these datum points. Once the datums are found, the camera reads their coordinate positions and sends them to the system's microprocessor for analysis. If there is any deviation, the microprocessor will issue a command to adjust the movement of the actuator through the control system, thus ensuring the precise alignment of the PCB. In order to guarantee the accuracy of positioning, it is usually necessary to set at least two reference points.
3、Component information database: The database stores the size of each component, the number of pins, pin spacing, and the type of suction nozzle that matches it.
4, the feeder configuration data: this part of the data specifies the feeder used by each component and its specific placement in the mounter feeding platform.
5, PCB board parameters: PCB data involves the size of the PCB board, the thickness of the PCB board as well as possible piecing board settings and other key parameters.
When all the above information is configured, you can start its mounter operation process on the mounter, (Note: different mounter manufacturers will be adjusted according to the order, there may be a gap).
