High-end solution for high-precision PCB placement

of the printed circuit in the gripper is recorded beforehand by the bottom camera. This requires a visual check on a reference pin. There is yet another quality control and visual inspection, in case pins have broken off, before the component is placed in position. Finally, the built-in force sensor and programmed force control ensure that nothing is damaged during placement. Although some force is required to press the pins into the openings on the PCB, a need for excessive force indicates that the positioning is not properly aligned with the pattern of the openings. Force measurement is therefore another control measure which guarantees a top-quality end product and a pristine machine. After placement, either the next component is placed or the PCB is fed towards the next process step, depending on the customer’s order.
