smt machine program management specification
The smt machine is a necessary production equipment in SMT production. The smt machine processing and production must be programmed. If the smt machine’s program management is not good, it is easy to cause bad batches of SMT products. Therefore, SMT processing companies must manage the smt machine program and make a set of reasonable management standards.
The engineers in the smt machine processing and production workshop combined the monthly plan and the BOM and PCB number map provided by the engineering department to prepare the product program for the new product proofing in advance to ensure that the program can be produced before going online.
For the permanent BOM changes issued by the SMT patch production engineering department, the engineer needs to modify the smt machine program backed up by the computer immediately. After the modification is completed, the new program needs to be copied into the computer backup to overwrite the old program, including the smt machine stored in it. Procedures to ensure that the product can be directly produced without adjusting the procedure before it goes online.
…
When the new product is produced for the first time, the engineer needs to enter the smt machine program into the smt machine to adjust the coordinates, angles, and parts database to ensure the smooth and qualified production of the new product.
Preparation for offline programming of smt machine
1. First, organize the customer’s BOM. Programming needs to be done on the computer, so it must be electronically filed. Generally in excel format
2. Extraction of coordinates. There are three situations:
(1) If the customer sends the coordinates of the exported excel or txt file, it is enough to directly use the programming software to merge the coordinates with the BOM you have organized.
(2) If the customer sends a PCB file, then you need to export the coordinates yourself. Generally, you can export it in excel format with protel99 or PADS2007.
(3) The customer only provides a BOM, but the coordinates are not available. At this time, a scanner is needed. After scanning the PCB, the points are saved in CAD format, and then the coordinates and BOM are combined.
3. After the BOM and coordinates are synthesized, check whether there is any omission or relocation. If there is, the engineering department needs to contact the customer to confirm, and save it in the format required by the machine after OK.
