Step, prepare the chip processing machine The main information required for chip processing programming:
1. Basic information of the PCB board, the length and width of the PCB board.
2.mark point basic information information, optical mark point coordinate parameters on the PCB board.
3.PCB board information, PCB board is how many consecutive plate.
4.SMT placement information, including placement number, coordinates, Angle, etc.
The customer will provide the corresponding BOM list, placement site number drawings, templates, etc.
The second step, the step of formal processing programming of the chip mounter: The formal programming of the chip mounter is divided into two stages, which is offline preparation work.
The second is online debugging.
The specific details of each SMT processing plant vary according to their respective SMT patch model number and management mode. The off-line preparation of the chip machine programming is as follows:
1. First sort out the BOM list provided by the customer, the programming needs to be carried out on the computer, so it is best to provide electronic files. Usually in excel format.
2. Extraction of coordinates.
According to the three types of documents provided by the customer:
(1) If the customer has sent the coordinates of the excel or txt document that has been exported, then directly use the programming software to combine the coordinates with the BOM list that you have sorted out.
(2) The customer sent the PCB file, then you need to export the coordinates yourself, generally with protel99 or PADS2007 you can export excel format.
(3) The customer only provides a BOM, can not provide coordinates, at this time you need a scanner, the PCB scan after the point saved into CAD format, and then the coordinates and BOM synthesis.
3. Check whether there is any omission or double position after the BOM and coordinate are synthesized. If there is, the engineering department needs to contact the customer to confirm, and save it into the format required by the machine after OK. Placement machine online programming debugging steps:
1. Import the programmed program into the smt mounter equipment;
2. Find the origin and make mark mark;
3. Gradually correct the digit coordinates;
4. Optimize the saving procedure, check the component direction and data again;
5. Turn on the patch piece to confirm. Previous: The role and maintenance of the main accessories of the placement machine Next: the factors that affect the quality of the placement machine
