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.

assembly of so-called peptoids (N-alkylglycine oligomers) we present a new synthetic methodology whereby N-heterocyclic carbene (NHC) based Pd ligands were assembled using a sub-monomer approach and loaded with Pd via solid-phase synthesis. This allowed the rapid generation a library of NHC-palladium catalysts that were readily functionalised to allow bioconjugation. These catalysts were able to rapidly activate
