Techniques for combining multiple materials or layers, often with specialized surface treatments, coatings, or assembly methods, to create functional or aesthetically enhanced plastic articles, including consumer goods and encapsulated electronics.

Methods and equipment for continuously shaping plastic materials by forcing them through a die, often involving screw extruders, heating elements, and downstream calibration.

Processes involving the application of heat and pressure to shape thermoplastic or elastomeric materials, often using molds or presses, to achieve specific forms or material properties.

Methods and tooling for forming structural components from fibrous materials impregnated with resin, involving processes like prepreg handling, resin infusion, and co-bonding during curing.

Methods and apparatus for cleaning polishing pads, dressers, chamber components, or finished substrates to remove residues, debris, or contaminants, often involving specialized nozzles, fluids, or mechanical actions.

Design and application of abrasive tools and deburring heads tailored for specific geometries, materials, or access constraints, including flexible, expandable, or multi-component designs for precision finishing.

Manufacturing methods for optical components such as lenses, waveguides, films, and filters, requiring high precision in molding, surface treatment, or material composition to achieve specific optical properties like refractive index, microstructures, or tinting.

Methods for temporarily attaching a wafer or substrate to a carrier for thinning, dicing, or other processing, followed by controlled debonding, often using light-sensitive resins, temporary adhesives, or roughened interfaces.

Systems and methods for precisely controlling welding parameters such as power, speed, oscillation, and material feed to optimize weld quality, consistency, and efficiency, often involving automated or semi-automated processes.

Techniques and devices for measuring, monitoring, and controlling the surface topography, film thickness, or other characteristics of a workpiece during or after grinding/polishing to achieve specific finish requirements.

Mechanisms and control systems for reliably feeding, conveying, and separating print media, including managing media roll changes, adjusting airflow, and adapting to different media characteristics.
