    Abstract: This invention is a zincating process of aluminum surfaces for subsequent plating in which the aluminum surfaces are cleaned, contacted with an acidic etching solution comprising a peroxygen compound, the acidic etching solution being substantially free of corrosive nitrate compounds, and contacting the aluminum surfaces with a zincate solution containing 6-60 g/l zinc and 100-500 g/l hydroxide ion. The acidic etching solution is substantially free of toxic inorganic fluoride compounds in order to simplify waste treatment. This invention may be understood with reference to FIG. 2, in particular Step 6.

    Abstract: A printed circuit board assembly employing a solder vent hole adjacent solder filled interconnect vias connecting to a conductive pallet, is disclosed. The solder vent hole allows gases to escape from an otherwise sealed cavity during solder reflow, relieving positive pressure and thereby allowing solder to flow into it. By providing an escape path for trapped air and gases generated during solder paste reflow, the out-gassing pressure and weight of the molten solder is sufficient to allow the solder paste to flow into the cavity.

    Abstract: The density of electronic packaging and the electrical reliability of the sub-assemblies utilizing stacked blind vias are improved by providing a blind, landless via in a first dielectric layer laminated to a conductive metal core serving as a ground plane or a power plane. A hole is provided through the dielectric layer extending to the core. A metal, such as copper, is deposited electrolytically using the metal core as the cathode, or electrolessly without seeding into the hole. The metal is deposited on the core and progressively builds in the hole to the depth required for the via. A second dielectric layer is laminated to the first, and is provided with a second layer blind via aligned with the first via. This second via may be formed by conventional plating techniques. Multiple dielectric layers with stacked blind vias can be assembled in this manner.
