We found the misalignment sometime during SMT 0402chips. So, we made the pick up speed a bit slower then the condition was better however it was time-consuming and delay shipment. We r using Yamaha 100Xg SMT M/C and no probelm in mounting 0602 or bigger than that. Is it caused by 0402 Feeders? Need feeder alignment? I'm seeking some advice if you have some idea for mounting 0402 chips and smaller than that.
Thanks in advance
