a high speed SMD placement system capable of placing 27,000 chips per hour using a dual gantry single PCB coveyor
find:
1) the maximum velocity in the head in only the x direction (neglect air resistance)
2) can a 0.5 hp motor be used to move the head in the x direction? assume 85% efficiency and a direct drive (no gearbox)
