Side Wall Frames

For over 25 years, A.T. Wall Company has been a leading producer of tubular side wall frames for hybrid microelectronic circuit packages used in defense, commercial electronics, and medical applications worldwide. These tubular frames serve as sidewalls for hermetically sealed flat packs that demand restrictive dimensional tolerance and precise metallurgical qualities.

The Warwick plant utilizes a unique manufacturing process involving hydraulic press forming of nickel alloy plate circles into cups, followed by traditional tube annealing, cold drawing, and cutting to size. A.T. Wall is currently the only sidewall frames manufacturer capable of producing Kovar tubular frames through this process.

In addition, a number of secondary operations are offered, including lap grinding and sidewall hole piercing.

If you require production quantities, you'll find that A.T. Wall is the undisputed leader when it comes to a broad selection of sizes, shapes, and materials... delivered fast.
