Compositions and methods useful for the singulation of fragile devices from substrates by the process of plasma singulation are described. Thermal resistant coatings comprising ingredients that exhibit both thermal resistance and water solubility are demonstrated. These ingredients which have high ultraviolet interaction allow laser interaction to create masks for thin and small devices, for example, substrates that are thin to 150 microns or less or have devices present that are measured 1 mm on a side or smaller. Methods are presented which apply the composition to the inorganic substrate whereby an ultraviolet sourced laser interacts with the surface and creates a mask which subsequently is processed in a plasma chamber to separate (singulate) the devices within the substrate and subsequently rinse with water to remove/dissolve the laser interactive and plasma protective layer. Once rinsed and clean, the devices proceed by pick and place tooling to final integration to electronic circuitry. The invention coating is a water rinsable creation that achieves high selectivity for both laser and plasma operations.

Methods and devices for forming painted circuits using multiple layers of electrically conductive paint. In one aspect, a painted circuit includes a substrate (111) and one or more paint layer (106, 108, 110, 112, 114, 116, 120, 122) applied to the substrate, where the one or more paint layers each form an electrical component of the painted circuit. A given paint layer of the one or more paint layers includes a conductive paint formulation having a resistance that is defined by a concentration of conductive material that is included in the conductive paint formulation and a thickness of the given paint layer, and lower concentrations of the conductive material included in the conductive paint formulation provide a higher resistance than higher concentrations of conductive material.

Provided are epoxy-based components and methods of fabricating such components. Specifically, an component comprises an epoxy-based composite part and a UV protective coating disposed over the part. This coating allows for the component to be exposed to UV radiation without any additional coating and without deterioration of the epoxy-based composite part. Specifically, the component may be exposed to interior lights and direct sun during its subsequent fabrication and/or transportation. The UV protective coating comprises polyurethane and silicate filler, such as hydrated aluminum silicate and/or hydrated magnesium silicate. The coating may have a transmittance of less than 1% or even less than 0.1% in the UV range. An epoxy primer layer may be formed directly over the UV protective coating followed by various other coatings, including a decorative finish.
