What are the main processes of SMT placement machine programming?

The SMT placement machineneeds to be programmed to operate and to perform placement processing. Programming is the first level of production and processing. Once it is not done well, the subsequent production process will not be able to proceed. Experienced engineers are very familiar with SMT placement machine programming, let the engineer to explain the main process of SMT placement machine programming for you in detail:

1. Edit the optimized product program on the SMT placement machine.

1. Call out the optimized program.

2. Make the image of PCB MarK and partial Mak.

3. Components without images need to be imaged and registered in the image library.

4. Unregistered components need to be registered in the component library.

5. Multi-tube vibrating feeders with unreasonable emissions need to be redistributed according to the length of the device body. As far as possible, arrange devices that are close to the length of the device body on the same rack. There may be no idle material stations in order to shorten the distance of picking up components.

6. Change the multi-pin, narrow-pitch devices with larger outlines, large-size PLCC, BGA, and long sockets in the program to Single Pickup to improve placement accuracy.

7. After saving, check whether there is any error message. If there is any error message, modify the program according to the error message until there is no error message.

2. Proofreading check and backup patch program

1. According to the component list in the PCBA process file, check whether the component name, tag number, model specification of each step in the program is correct, and correct the incorrect place according to the process file.

2. Carefully check whether the components of the placement machine feeder station are consistent with the picking program table.

3. Through the main camera, check whether the X and Y coordinates of the components are consistent with the PCB component center, and check whether the schematic diagram of the component position and the corner Θ are correct according to the process file. If it is not correct, it needs to be corrected. This step can also be corrected according to the actual deviation after the first piece of SMT is mounted.

4. The correct product program needs to be copied to the backup U disk for storage.

5. After the proofreading check is confirmed to be correct, the production will start.

The above is the main process of SMT placement machine programming explained by the editor. I hope it will help your career!
