CHENGSHUO | ENGINEERING CONCEPT REVIEW Reference concept: Coaxial center contact Page: https://chengshuoprecision.com/components/shafts-and-pins/coaxial-center-contact/ Our component / drawing revision: [ ] Assembly and mating interfaces: [ ] Please review: 1. Contact drawing with socket, insulator and termination interfaces 2. Approved base alloy, complete coating specification and finished dimensions 3. Quantities, dimensional records and connector-level validation responsibilities Sample acceptance to agree: 1. Mating tip: Define diameter, usable length, lead-in geometry and finished condition. 2. Insulator seat: Control locating diameter and shoulder position to the mating interface. 3. Termination cup: Specify cup depth, wall and access opening with internal edge requirements. 4. Coating allowance: Agree dimensions after plating and required finish documentation. Material grade / finish: [ ] Sample / production quantities: [ ] Target timing / delivery destination: [ ] AI-generated engineering concept, not a production photograph or completed delivery. Feasibility, process route and acceptance criteria require review of our actual drawing.
