Abstract
Official abstract text for this publication.
A polymerizable composition includes at least one monomer, a photoinitiator capable of initiating polymerization of the monomer when exposed to light, and a phosphor capable of producing light when exposed to radiation (typically X-rays). The material is particularly suitable for bonding components at ambient temperature in situations where the bond joint is not accessible to an external light source. An associated method includes: placing a polymerizable adhesive composition, including a photoinitiator and energy converting material, such as a down-converting phosphor, in contact with at least two components to be bonded to form an assembly; and, irradiating the assembly with radiation at a first wavelength, capable of conversion (down-conversion by the phosphor) to a second wavelength capable of activating the photoinitiator, to prepare items such as inkjet cartridges, wafer-to-wafer assemblies, semiconductors, integrated circuits, and the like.
First claim
Opening claim text (preview).
The invention claimed is: 1. An anisotropic conductive polymer sphere comprising a polymeric core having at least a portion of an outer surface of the sphere coated with at least one down-converting material that responds to X-ray photons. 2. The anisotropic conductive polymer sphere of claim 1 , further comprising an outer coating of silica. 3. The anisotropic conductive polymer sphere of claim 1 , wherein the at least one down-converting material is in a form of nanoparticles. 4. An anisotropic conductive polymer sphere comprising a polymeric core having at least a portion of an outer surface of the sphere coated with at least one up-converting material that responds to near infrared photons. 5. The anisotropic conductive polymer sphere of claim 4 , further comprising an outer coating of silica. 6. The anisotropic conductive polymer sphere of claim 4 , wherein the at least one up-converting material is in a form of nanoparticles.
