Stamping of Aluminum Inlaid Copper Leadframe for the Automotive Industry

At G&M Manufacturing we specialize in multiple capabilities including stamping and various ancillary processes. In this project a customer in the automotive industry needed a terminal and leadframe array for an automotive hybrid circuit. This circuit required wire bonding to aluminum inlayed surfaces. The primary process was stamping with our 80 ton press. After stamping we utilized our vapor degreaser to clean the C194 Aluminum inlay leadframe. Overall part dimensions were 58 mm x 56 mm x 4 mm with a material thickness of .064 mm. At G&M we stand behind our work, the quality of this part was verified through OGP vision inspection to verify part integrity and the required ±.025 mm tolerances. We manufacture 85,000 parts annually for this customer. This project features our capabilities to manufacture and finish parts utilizing multiple applications and materials.
