A position detector senses a position of the leadframe sheet as the leadframe sheet moves along the machine track. A controller including a processor is coupled to the position detector for receiving the position of the leadframe sheet. A pressurized gas stopper is positioned within the inner space including a gas distributor having at least one gas inlet for receiving a pressured gas supply and at least one gas outlet for directing a flow of gas toward the leadframe sheet sufficient to stop movement of the leadframe sheet. The controller provides control signals for controlling the flow of gas to provide non-contact stopping of the leadframe sheet at one or more locations along the machine track."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pressurized gas stopper for leadframe transporting apparatus","description":"An apparatus for transporting a leadframe sheet during semiconductor die assembly includes a rail having sub-rails defining a machine track and an inner space along which the leadframe sheet is moved.","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9721818","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
