Abstract: The invention relates to a ball-limiting metallurgy (BLM) etching system and process. The BLM stack is provided for an electrical device that contains an aluminum layer disposed upon a metal first layer. A metal upper layer is disposed above the metal second layer, and an alternative metal third layer is disposed between the metal second layer and the metal upper layer. The etching system and process utilizes an etching solution that includes a nitrogen-containing heterocyclic compound, an ammonium hydroxide compound, an oxidizer, and a metal halide compound. Etching conditions prevent any metallization that is dissolved from redepositing, thus avoiding lowered yields.

Abstract: “BOX HANDLES” are handles that are applied to an ordinary shipping box in order to make the box easier to lift and carry. The handles are made of two parts, one being the handle, the other being the handle re-inforcement piece. The two parts are attached to each other with adhesive to form one finished handle. Two of these finished handles are then attached to a box. One to each side panel. When the box is filled, closed and ready for shipping, the handles make the box easier to lift and carry.
