Methods and apparatuses for roll coating are provided. The roll coating system () includes a coating roll () having a deformable inner layer () with a surface thereof covered by a deformable outer layer (), the inner layer being softer than the outer layer. A substrate () is conveyed to the nip () between the coating roll and a back-up roll (). A metered coating material is transferred from the coating roll to a patterned surface structure () of the substrate at the nip to form a conformal coating on the patterned structure of the substrate.

Methods and apparatuses for screen or stencil printing a pattern on a substrate are provided. The substrate () has its major surface in contact with a first major surface () of a stencil shell () having apertures (). A coating material is disposed onto the second major surface () of the stencil shell () to flow through the apertures () to contact the substrate (), where the coating material is at least partially cured. The substrate () is separated (C) from the first major surface () of the stencil shell () after the curing () and a pattern () of the at-least-partially-cured coating material is formed on the substrate ().

Methods and apparatuses for applying coatings on a moving web are provided. A coating die and a back-up roll engage with each other. The back-up roll includes a shell rotatably supported by a pressurized air layer. When a coating material is dispensed from the coating die onto the web to form a liquid coating, the pressure of the air layer is controlled such that the shell translates in space to balance forces from the air layer and the coating bead, while the web is being translated to drive the shell.

A printing system () including a printing roll () is provided. The printing roll () includes an elastically deformable and compressible inner layer () and a thin outer shell () to cover the inner layer (). The thin outer shell () includes a pattern of raised print features () to receive ink material thereon. The inner layer () is softer and thicker than the thin outer shell (), and optionally, the thin outer shell () is removable from the inner layer (). The inner layer () of the printing roll () has a thickness, a compression force deflection value and an elastically-deformable compressibility such that the raised print features () of the printing roll () do not slide or deform with respect to the printed web () in an amount to generate a substantially visible dot gain.

A composite article includes a conductive layer with nanowires on at least a portion of a flexible substrate, wherein the conductive layer has a conductive surface. A patterned layer of a low surface energy material is on a first region of the conductive surface. An overcoat layer free of conductive particulates is on a first portion of a second region of the conductive surface unoccupied by the patterned layer. A via is in a second portion of the second region of the conductive surface between an edge of the patterned layer of the low surface energy material and the overcoat layer. A conductive material is in the via to provide an electrical connection to the conductive surface.

Methods of passivating an adhesive via printing an ink onto a release liner, and adhesive articles or products made by the same are provided. An ink pattern is printed onto a release liner to form a pattern of features. The features are at least partially embedded in an adhesive layer such that when the release liner is peeled from the adhesive layer, the passivation features remain with the layer of adhesive to form selected areas having adjusted adhesive functionality. Articles including the passivated adhesive on a release liner are also disclosed.

Electronic devices including a layer of polymeric material and solid semiconductor dies partially embedded in the layer are provided. The dies have first ends projecting away from the first major surface of the layer. The electronic devices can be formed by sinking the first ends of the dies into a major surface of a liner. A flowable polymeric material is filled into the space between the dies and solidified to form the layer of polymeric material. The first ends of the dies are exposed by delaminating the liner from the first ends of the dies. Electrical conductors are provided on the layer to connect the first ends of the dies.

Processes for automatic registration between a solid circuit die and electrically conductive interconnects, and articles or devices made by the same are provided. The solid circuit die is disposed on a substrate with contact pads aligned with channels on the substrate. Electrically conductive traces are formed by flowing a conductive liquid in the channels toward the contact pads to obtain the automatic registration.

Automatic registration between circuit dies and interconnects

A method of patterning a conductive layer to form transparent electrical conductors that does not require etching is disclosed. The method includes peeling a strippable polymer layer from a substrate coated with the conductive layer to pattern the conductive layer. In some embodiments, a resist matrix material is patterned over the conductive layer to prevent removal of the conductive layer beneath the resist matrix material. In other embodiments, a liner having a pressure sensitive adhesive surface is brought into contact with the patterned strippable polymer material to remove both the patterned strippable polymer material and the conductive layer beneath it.
