Cover Assemblies

The interior of any electrical system is where all its core functions occur, within wires, batteries, circuits, microchips and more. To ensure long life, sufficient protection must be engineered to protect high performance circuits. COINING’s Cover Assemblies (CCA) designed and manufactured provide the necessary hermetic seal for delicate electrical components in even the harshest of environments. Our CCAs improve on the traditional methods of assembly, alignment, and attaching individual parts by supplying one integrated cover assembly that mates to the IC package.

How it’s made
Our CCA’s are made by implementing a Microstamping and Solder preform which are stamped and welded together. This process is done either manually or automated. Our fully automated manufacturing capability can easily scale to a wide range of volume needs. It is determined by the size of the CCA, the smaller the CCA the more automated the process. Our engineering team can help you design a cost-effective solution that will work the first time, every time and for extended life in the harshest environments.
