  • Publication number: 20220173066
    Abstract: Embodiments of the present disclosure are directed to using direct ink printing on chips or interposer pads to replace the other die bonding process, e.g., conductive adhesive, Anisotropic Conductive Film (ACF), solder, etc. Direct printing on contact pads of chips and/or interposers to replace using ACF bonding provides simplicity of manufacturing process, reduced cost by eliminating ACF, reduced interconnect resistance by eliminating ACF interface, and increased reliability by eliminating ACF bonding instability. Direct printing according to embodiments of the present disclosure can make complex design patterns with fine pitch capability (sub 10 micron is feasible by using aerosol jet printing, 30 microns or above for screen printing). Such direct printing can also enable roll to roll printing process for high volume production.

  • Publication number: 20220132651
    Abstract: Heat management in electronic components is an important factor in managing the performance and longevity of such electronic components. By omitting a thermal interface layer and providing thermal vias between a heatsink and an electronic component, such as a surface mount technology (SMT) package, such components may improve thermal transfer to the heatsink and simplify assembly. Thermal vias may be fused during reflow to the heatsink and/or electronic component. As a benefit to the improved heat transfer provided, electronic components may operate at a lower temperature or be configured to perform greater heat-producing activities.

  • Publication number: 20220025218
    Abstract: An antimicrobial metallized thin film is provided that can be quickly and easily attached to surfaces of objects. This film includes a polymer substrate onto which a metallized layer is formed. The metallized layer comprises an exposed antimicrobial metal physical contact surface. Ions from this physical contact surface destroy the viral coating and ribonucleic acid of contacting viruses rendering the viruses inactive and noninfectious. The film can be attached via an adhesive layer disposed between and in contact with the polymer substrate and the communal surface. This arrangement allows the film to economically refurbish communal surfaces with a film overlay rather than completely replacing communal surfaces with antimicrobial materials. The film mitigates the likelihood of viruses such as coronaviruses, noroviruses, rhinoviruses, and the like from spreading due to contact with the refurbished communal surfaces.
