Abstract:

The invention features and methods and compositions for oxide production on a Copper substrate, e. g. , a Copper or Copper alloy substrate, to provide for improved adhesion of Copper substrate to polymeric material, e. g. , such as used in manufacture of printed circuit boards. The oxide-producing compositions of the invention, which may be either acidic or ammoniacal, comprise 1) a source of Cu (Cupric) ions; 2) a source of a primary electrolyte that is non-interactive with Copper ions; 3) a Cuprous ligand, e. g. , a halide ion, preferably chloride, which also serves as a secondary electrolyte; and 4) an optional organic. Acidic oxide-producing compositions comprise a strong acid as the primary electrolyte. The primary electrolyte of ammoniacal oxide-producing compositions is a non-interactive, ammonium salt of acid, which provides a highly soluble Cupric ammonium salt. The secondary electrolyte of the oxide-producing compositions is selected so as to be compatible with the primary electrolyte.

Abstract:

A cylindrical housing includes a piston displaceable therewithin, wherein the piston includes a piston plate mounted to an opposed end of a piston rod, wherein the piston plate is in operative communication and directed through a guide tube having a tube floor to effect crushing of an associated can member directed between the piston plate and the guide tube floor. Feet structure is arranged to intersect the guide tube between the piston plate and the guide tube floor to properly position a can member to effect crushing thereof.
