A customer in the automotive industry needed a brass leadframe insert for an automotive transmission control unit. At G&M Manufacturing, our unique mix of stamping and secondary operations were the right mix for this project. Initially we used our 60 ton capacity Bruderer straight side press to stamps the brass leadframe. We used half hard temper C260 brass with a thickness of .02″. The overall part dimensions were 4.3″ long, 2.2″ wide and .15″ high and kept within a ±.001″ tolerance which was required for the subsequent insert molding process. An X-ray machine was used to verify the thickness of the palladium. Per the customer’s specifications the leadframe insert was finished with palladium plating over a nickel undercoat. We also conducted OGP vision system inspection for our 400,000 annually fabricated parts. This project features our unique stamping and plating capabilities for high volume projects.
