Embedded FMS has many advantages, such as control flexibility, simplicity, good real-time, low cost etc. Open CNC system integrated embedded FMS can solve the existing problems between traditional NC system and industrialized production of NC application software. This paper adopts the structure of “NC embedded PC type”, designed an open CNC system based on the IPC and movement control card. The open...
Currently, ball grid array (BGA) is the mainstream technology of semiconductor package. The alignment accuracy of BGA ball mounting processing has a great impact on the rate of finished products. In order to reduce the accuracy requirement for mechanism and increase the automation level, visual servo technology is introduced to BGA ball mounting processing in tins paper. Coaxial lighting is adopted...
