In this paper, three-dimensional finite element analysis using the commercial ANSYS software is performed to study the thermal performance of a thermally enhanced FC-PBGA (flip-chip plastic ball grid array) assembly in both natural and forced convection environments. The thermally enhanced FC-PBGA assembly is a basic FC-PBGA assembly with a lid attached on top, after which an extruded-fin heats...

Acrylic polymers are widely used for fabricating pressure-sensitive adhesives (PSAs) with the inherent unique advantages of transparency and superior intrinsic adhesive properties over other polymer-based adhesives. In this study, we have developed and evaluated a method of obtaining by radical copolymerization PSAs for liquid crystalline (LCD) applications. Various factors including the amount...

The polymer poly(2-ethyl-2-oxazoline), sold under the trade name Aquazol, is gaining appeal for many conservators due to its excellent adhesive qualities and wide-ranging solubility in polar organic solvents including water. This chemically stable polymer is being used as an adhesive, clear coating, and consolidant. During the last year, substitutions of Aquazol-solvent solutions for hide glue ...

The viscosity of polymer liquid is an important parameter used in oilfield. Understanding the loss rule and regularity will help to improve distribution water injection quality ensure effective liquid. According oil-water data previous flooding fluid, it found that within range 5%-20%, with average 9.8%. reasons single well pipeline are complex varied, which closely related reducing substances,...

The properties of thin polymer films are known to be different than the properties of bulk polymers. Both dewetting studies1,2 and temperature-dependent thickness measurements3 showed that thin polystyrene films can exhibit polymer mobility even at temperatures well below that of the bulk-polymer glass transition (Tg). Subsequent work by a wide range of groups has shown that the thermal propert...

The adhesive proteins employed by mussels have very specialized amino acid compositions undoubtedly related to the particular challenges of achieving permanent adhesion in the wet marine environment. Mussel adhesive proteins (MAPs) are known to contain high levels of the catecholic amino acid 3,4-dihydroxy-L-alanine (DOPA). Catechols are versatile in a chemical sense, participating in redox rea...

AddJoining technique has been recently introduced to produce metal–polymer composite hybrid layered structures. The methodology combines the principles of joining and polymeric additive manufacturing. This paper presents three process-variants investigated demonstrated for material combination aluminum 2024-T3 acrylonitrile butadiene styrene form single lap joints. microstructure mechanical per...

The interest in the development of biobased adhesives has increased due to environmental concerns. Moreover, as production engineered wood products (EWPs) is expected grow, market needs transit toward formaldehyde-free products. Cellulose nanoparticles (CNPs) are a material with unique properties and advantages for producing hybrid materials adhesives. Besides their traditional use reinforcing ...
