SMT production refuelling requires the operator to check the same material, machine and station position when loading, and inform IPQC to check and confirm. The wrong material connection is a major production anomaly. You have to review, first of all, pay attention to what is wrong, and second, pay more attention in the future. Finally, have a good attitude, and pay attention to those links when receiving materials in the future.
The wrong material is inevitable in SMT production, and the probability of serious appearance will be much less. It also depends on whether your company's management and supervision system is complete!
