Surface mount technology is a method of applying lead solder to PCB pads to fix Surface Mount Device (SMD) components on PCBs. SMT facilitates the pickup of the electronic component and accurate placement on PCBs. Heads and nozzles for each axis use suction cups to pick up electronic components from tape feeders. The components are inspected before a vision camera to check pickup location and alignment, and then are moved to PCBs waiting on the conveyer for placement. This paper presents an algorithm that identifies the shortest path from sLa to pLb without stopping before the camera for visual inspection. The simulations verified that the fly motion method reduced the time involved by 16% compared to the stop motion method.
