The first step, prepare the main information needed for the programming of the placement machine placement processing:
1. PCB board basic information, PCB board length, width and thickness.
2. mark point basic information, PCB board on the optical mark point coordinates parameters.
3. PCB board wrench information, PCB board is how much even wrench.
4. SMT placement position information, including placement bit number, coordinates, angle, etc.. The customer will provide the corresponding BOM list, SMD bit number drawings, sample boards, etc.
The second step, the chip machine formal processing programming steps: chip machine formal programming is divided into two stages, one is offline preparation work.
The second is online debugging. Each SMT processing plant according to the respective SMT machine models and management model different specific details also vary.
The offline preparation work for the programming of the chip machine is as follows:
1. First collate the BOM list provided by the customer, programming needs to be carried out on the computer, so it is best to provide the electronic file. Usually in excel format.
2. Extraction of coordinates. According to the files provided by the customer, there are three kinds of files as follows:
(1) If the customer sends an excel or txt document with the coordinates already exported, then directly use the programming software to merge the coordinates with the BOM list you have organized.
(2) The customer sent the PCB file, then you need to export the coordinates yourself, generally with protel99 or PADS2007 can export excel format.
(3) the customer only provides a copy of the BOM, can not provide coordinates, then you need a scanner, the PCB will be scanned and save the points into CAD "format, and then the coordinates and BOM synthesis.
3. BOM and coordinate synthesis after checking whether there are missing or repositioned, there is a need for the engineering department to contact the customer to confirm, OK after saving into the format required by the machine.
The debugging steps of the online programming of the chip machine:
1. Will be programmed into the smt placement machine equipment:
2. Find the origin and make mark mark:
3. The bit number coordinates will be gradually corrected;
4. Optimize and save the program, check the component direction and data again;
5. Start the SMD machine and confirm the first part.
