    Abstract: Method and apparatus for determining a quality or characteristic of connectors in electronic components is provided. Methods include applying a UV-responsive indicator solution active for Pd, Ni, or Cu to a connector on an electrical component; irradiating the connector with UV radiation; detecting a response to the UV radiation; and determining a quality of the connector based on the response to the UV radiation. Apparatus includes an enclosure; a support; a dispenser oriented toward the substrate support; a source of UV-responsive indicator solution active for Pd, Ni, or Cu ions fluidly coupled to the dispenser; a UV source coupled to the enclosure; and a radiation sensor positioned to detect light inside the enclosure.

    Abstract: A process of forming a macromolecular block copolymer includes forming a first high molecular weight polymer using a first extruder of an extruder system that includes multiple extruders. The first extruded high molecular weight polymer has a first length terminating at a joiner of the extruder system and has a first set of material properties along the first length. The process also includes forming a second high molecular weight polymer using a second extruder of the extruder system. The second extruded high molecular weight polymer has a second length terminating at the joiner of the extruder system and has a second set of material properties along the second length. The process further includes bonding the first extruded high molecular weight polymer to the second extruded high molecular weight polymer to form a macromolecular block copolymer having a first segment of the first length and a second segment of the second length.
