The instant invention relates to a method for treating a surface of a metal, a metal alloy or a metal oxide by contacting the at least one section of said metal, metal alloy or metal oxide with an acidic aqueous precoat solution comprising one or more than one tetrazole and/or triazole in combination with an acidic cleaning step which is performed either prior to or following the precoat step. It has surprisingly been found that when such pretreated surfaces are subsequently contacted with triazine compounds that the surfaces exhibit an improved resistance to delamination under thermal, humidity, and chemical stress conditions. This is demonstrated by increased adhesion strength and wedge void reduction.

A laser-processing apparatus for forming features in a workpiece includes at least one sensor for generating process control data representing a) at least one characteristic of the apparatus either before, during or after the workpiece is processed to form a set of features, b) at least one characteristic of the workpiece either before, during or after the workpiece is processed to form a set of features, and/or c) at least one characteristic of an ambient environment in which the apparatus is located either before, during or after the workpiece is processed to form a set of features. A controller executes, or facilitate execution of, a candidate feature selection process whereby process control data is processed to estimate whether any of the features formed in the workpiece are defective and the location of any feature estimated to be defective is identified.

The instant invention relates to an electrolyte solution for a battery, the solution comprising an additive selected from the group consisting of polyquaternized polymers; the invention further relates the use of such additive and a battery comprising said additive.

Numerous embodiments are disclosed. Many of which relate to methods of forming vias in workpieces such as printed circuit boards. Some embodiments relates techniques for indirectly ablating a region of an electrical conductor structure of, for example, a printed circuit board by spatially distributing laser energy throughout the region before the electrical conductor is indirectly ablated. Other embodiments relate to techniques for temporally-dividing laser pulses, modulating the optical power within laser pulses, and the like.

An apparatus for non-immersive wet-chemical treatment of a surface of a workpiece (2) comprises: a holding device (7) for holding the workpiece (2) with the surface in a predominantly upright orientation; a liquid application system (5) for flowing liquid (6) across the surface of the workpiece (2), when held by the holding device (7), as a film flowing in a predominantly downwards direction; a receptacle (4) for collecting liquid (9) that has flowed across and detached itself from the surface; and a system (11,12,16,18-20,22,24) for recirculating liquid collected in the receptacle (4) to the liquid application system (5). The system (11,12,16,18-20,22,24) for recirculating liquid comprises a device (22,23) for introducing sparging gas (21) into the liquid.
