The document describes the process of an inline sequencer configuration for surface mount component assembly. Components are indexed from ammo boxes or reels by dispensing heads and cut from tape. The components are then snapped into carrier clip clamps on a conveyor chain. As the chain travels, the components are verified, have leads cut, and are sensed to check for missing components before being transferred to insertion heads. The insertion heads guide the components into PCB holes, push the components down, and the clinch cuts and clinches the leads before retracting.
