T Stamped Copper Heat Sinks for the Electronics Industry

(click on thumbnail to enlarge)

An electronics customer contracted OMNI Engineering, Inc. to manufacture these circuit board heat sinks to be used across various product applications. Composed of C102 copper and C110 half-hard copper, the customer's drawings called out dimensions of .064" to .250" in length, .140" to .517" in width, and .0314" to .375" in thickness. The miniature/micro miniature progressive stamping was performed on our 22 ton Bruderer presses. This capability allows us to meet tolerances of ±0.0005" throughout the 20,000 to 50 million of these components that we produce annually. After stamping the heat sinks are deburred, this is followed by the application of matte sulfate nickel and tin plating with inlayed materials such as tin and silver.

Quality is maintained through dimensional and visual Inspection, and the use of an F.O.V. Smartscope, automated inspection system. All parts meet MIL-STD-202 standards for solderabilty, with orders being manufactured with 2 to 4 week lead times.
