Abstract: The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.

Abstract: The present disclosure generally relates to adhesive mounting assemblies that are capable of attaching or adhering to a surface and that can be removed from the surface without causing damage to the surface. In some embodiments, the mounting assemblies are peeled off the surface. The present disclosure generally relates to adhesive articles including a mounting device. The adhesive articles have one or more adhesive areas (which can be part of one continuous adhesive area) exhibiting adhesive properties and one or more non-adhesive areas that lack significant adhesive properties. At least one of the non-adhesive areas is located in an area and/or has a size, shape, and/or geometry that lowers and/or controls at least one of the average peel force and/or the peak peel force of the adhesive article such that the peel force of the adhesive article does not exceed the threshold for causing damage to the surface from which the adhesive article is peeled.

Abstract: A peelable adhesive article capable of adhering to a substrate wherein subsequent removal of the adhesive does not damage the substrate, and methods of making and using said peelable adhesive article. The adhesive articles comprise a peelable adhesive adjacent to a major surface of a backing, wherein the backing has a modulus of elasticity and/or modulus of secant between 100 to 18,000 psi as measured by ASTM D638-14 and/or ASTM D412-06a. The backing may be a multilayer backing comprising a core layer and at least one skin layer in a ratio of 2:1 to 100:1.

Abstract: A method of making a sacrificial fiber, comprising: forming a molten sacrificial composition comprising a poly(hydroxyalkanoate) and a metal catalyst; extruding the molten sacrificial composition to form a sacrificial fiber comprising the poly(hydroxyalkanoate) and the metal catalyst, where the concentration of the metal catalyst in the sacrificial fiber is at least 0.1 wt %.

Abstract: An enhanced substrate for making a printed circuit board (PCB) includes a silane applied to the ends of glass fibers in via holes. In one embodiment, during a plated through-hole (PTH) via fabrication process, glass fiber bundles exposed in a drilled through-hole are selectively sealed. For example, after the through-hole is drilled in a substrate, the substrate may be subjected to an aqueous silane bath (e.g., an organo trialkoxysilane in an aqueous solution of an acid that acts as a catalyst) to deposit a layer of silane on the exposed glass fiber bundle ends. For example, trialkoxy groups of the silane may react with exposed silanols on the glass to form a siloxane, which is further polymerized to form a silane polymer barrier layer on the exposed glass fiber ends. The barrier layer effectively seals the glass fiber bundles and eliminates the conductive anodic filament (CAF) pathway between PTH vias.

Abstract: An enhanced mechanism for via stub elimination in printed wiring boards (PWBs) and other substrates employs laser resin activation to provide selective via plating. In one embodiment, the resin used in insulator layers of the PWB contains spinel-based non-conductive metal oxide. Preferably, only insulator layers through which vias will pass contain the metal oxide. Those layers are registered and laser irradiated at via formation locations to break down the metal oxide and release metal nuclei. Once these layers are irradiated, all layers of the PWB or subcomposite are laid up and laminated. The resulting composite or subcomposite is subsequently drilled through and subjected to conventional PWB fabrication processes prior to electroless copper plating and subsequent copper electroplating. Because metal nuclei were released only in the via formation locations of the appropriate layers, plating occurs in the via barrels only along those layers and partially plated vias are created without stubs.
