The invention provides a high-precision full-automatic BGA repair
workbench. The high-precision full-automatic BGA repair
workbench comprises a handpiece portion mechanism, an X-axis motor, an X-axis sliding rail, a Y-axis sliding rail, a Y-axis motor, a picking-up mechanism, a PCB supporting device, a cooling device, a feeding mechanism, a preheating box, an X shaft, a Y shaft, a datum base plate, a preheating device, a lower hot-air mechanism, a lower CCD vision mechanism, an upper
machine body cover and a lower
machine body cover. The handpiece portion mechanism is arranged on the X-axis sliding rail and comprises a handpiece fixing base, a
surface mounting mechanism, an upper heating mechanism, an upper CCD vision mechanism, a headpiece cover, a heating motor, a
surface mounting motor, a heating motor fixing base, a
surface mounting motor fixing base, a coupler, a lead screw fixing base, a lead screw and a Z-axis sliding rail. According to the high-precision full-automatic BGA repair
workbench, a vision automatic alignment
system is adopted, image capturing and locating are conducted on a PCB and a BGA through a CCD, accurate alignment and surface mounting are achieved through analysis and deviation rectification by
image processing software, and the surface mounting precision can reach + / -0.025 mm; in this way, the consistency of
work quality is guaranteed, and high-end precise electronic products are easily processed.
