The heat dissipation is very important for electronic packaging. We have improved the thermal conductivity of electronic packaging materials by modifying epoxy resin with tetraester diepoxide monomers (TEDE). TEDE was synthesized with p-hydroxybenzoic acid, allyl bromide and glycols, and characterized by 1H-NMR. TEDE modified epoxy resin (TMEP) was cured by 4, 4 '-diaminodiphenyl-methane (DDM). Thermogravimetric (TG) analysis show that the decomposition temperature of TEDE is above 280 °C, and the decomposition temperature of TMEP is above 300 °C in nitrogen atmosphere. Differential scanning calorimetry (DSC) and polarized optical microscope (POM) were employed to illustrate that TEDE is liquid crystalline polymer form room temperature to 220 °C. Dynamic mechanical analysis (DMA) illustrate that the glass transition temperature (Tg) of TMEP materials decrease with the content of TEDE increase. The thermal conductivity was measured by laser thermal conductivity testing equipment. The results show that the glass transition temperature (Tg) of 30%TEDE modified epoxy resin is above 130°C, and the thermal conductivity is 0.64w/(m·K).
Graphene-based films (GBF) were fabricated using a chemical conversion process including graphene oxide (GO) preparation by use of Hummer's method, graphene oxide reduction using L-ascorbic acid (LAA), and finally film formation by vacuum filtration. GBF is considered as a candidate material for thermal management, i.e. for removing heat from hotspots in power electronic packaging, due to its high thermal conductivity. In this work, the GBF heat spreading performance in 3D TSV packaging was analysed using finite element methods (FEM) implemented in the COMSOL software. Both size effects and the influence of the thermal conductivity of the GBF heat spreader on the thermal performance of the 3D TSV package were evaluated. Furthermore, the size effects of the thermal conductive adhesive (TCA) underfill between the chip and the printed circuit board (PCB) were analysed. The results obtained are critical for proper design of graphene-based lateral heat spreaders in high power electronic packaging.
Electronic packaging polymers filled with various solid additives such as silica, flame retardant, etc. have excessively been required for the use in advanced IC packages in recent years. It's necessary to predict the mechanical properties of these electronic packaging materials. On the basis of structural and mechanical characterization of particle filled epoxy materials, a new three-phase (dispersion phase, interface phase, and continuous phase) constitutive model and its simulation calculation are performed for the mechanical properties of the particle filled electronic packaging polymer in this study. In this paper, the interface chemical principle and three phase constitute model are combined, which improve the mechanical property's calculation and composition design method of electronic packaging polymer. With this model, the relationship between mechanical properties of the electronic packaging materials and modulus of matrix, solid particles content, particle size, gradation and thickness of the interface adhesive layer were constructed mathematically. This relationship and its derived patterns can be used in not only the prediction of the mechanical properties of electronic packaging materials but also the instruction of the composition design for particle filled electronic packaging materials
With the electronic packaging techniques and electronic equipments toward a high integration and miniaturization development, high thermal conductivity and excellent thermo-mechanical properties of polymer-based composites have attracted significant attentions in the recent years. SiO2as a common inorganic filler has been widely used in electronics packaging materials, due to its low coefficient of thermal expansion, high storage modulus, high glass transition temperature and stable chemical properties. Although the filling of SiO2can improve the thermo-mechanical properties of polymer-based composites, its lower thermal conductivity limits its application in the field of electronic packaging. Boron nitride (BN), so-called “white graphene”, which has excellent physical and chemical properties, such as excellent mechanical strength, low coefficient of thermal expansion, high resistance to oxidation, outstanding corrosion resistance and high thermal conductivity. Therefore, we hope to combine the excellent properties of SiO2and BN to prepare polymer- based composites with high thermal conductivity and excellent thermo- mechanical properties. In our work, the SiO2@BN hybrids with core-shell structure were successfully prepared by high temperature calcination in nitrogen, and then filled into the epoxy resin to obtain the SiO2@BN/epoxy composites. When the SiO2@BN content was 50 wt%, the thermal conductivity of composites is 2.73 Wm-1K-1, which is about 4.07 times of neat epoxy. The storage modulus (50 °C) and glass transition temperature of the 50 wt% SiO2@BN/epoxy composites are 6.09 GPa and 188.4 °C, which is 3.72 GPa higher than that of the neat epoxy and 54.9 °C higher than the glass transition temperature of the neat epoxy. In addition, the coefficient of thermal expansion of the 50 wt% SiO2@BN/epoxy composites is 31.5 ppm/°C, which is 36.9 ppm/°C lower than the coefficient of thermal expansion of the neat epoxy.
With the rapid development of electronic manufacturing technology, the metallic materials used for electronic packaging products have strongly requirements of improved the performance and reliability. Space material science is an emerging field of space technology and material science. The space environment has the characteristics of containerless, microgravity and ultra high vacuum. The highly undercooled liquid metal can be rapidly solidified under space environment, which provides an effective way to prepare metallic materials with significantly refined microstructure and excellent physicochemical properties. The solidification of metal materials in the space environment has shown a wide application prospect in the field of electronic equipment manufacturing. This article starts with the electrostatic levitation technology, summarizes the recent research results of space materials science, and provides new ideas for the development and preparation of new metal materials for electronic packaging.
Au-30at.%Sn eutectic alloy is useful in electronics for its superior mechanical and thermal conduction properties. Compared with traditional methods (Au-Sn solder preform and evaporation), the electroplating is an attractive method to obtain Au-Sn solder due to its cost-effective. In this work, Au-Sn films were co-electroplated via a pyrophosphate based bath. Electrochemical studies have been conducted to examine the effects of bath temperature on plating process. It was found that the rate for deposition of Au-Sn alloys was increased with bath temperature increased. Besides, the effects of bath temperature on the morphology and composition of electrodeposits were discussed.
With the development of microelectronics and semiconductor, the density of electronic packaging increases quickly, which result in the high demand to the material. Aluminum reinforced with silicon carbide particles composites is one of potential materials for electronic packaging with its excellent properties such as low density, high thermal conductivity, lower coefficient of thermal expansion etc. In order to obtain the final product, packaging component of Al/SiCp must to be bonded with different materials in practical application. It is significant practical to research the infiltration bonding of aluminum silicon carbide electronic packaging materials and metal component. Al/SiCp electronic packaging materials embedded metal components are fabricated by gas pressure infiltration. The microstructure of interface is observed by EDS and XRD, Bend strength is in order to test the joint strength. The result shows that during the fabrication process of Al/SiCp electronic packaging materials, the reliable joint between composites and solid metal (FeNi<sub>50</sub>, Ti) can be realized. In the research of the infiltration bonding of Al/SiCp/FeNi<sub>50</sub>, it is found that (Fe,Ni)<sub>2</sub>(Al,Si)<sub>5</sub> layer and (Fe,Ni)<sub>4</sub>(Al,Si)<sub>13</sub> layer all exist in the interface reactive layer of the joint. With the increment of the infiltration bonding temperature, thickness of the former approximately stay the same, and the relationship between the latter and temperature is near linear. As a result of the formation of intermetallic compound, bending strength of joint is low. Interface bending strength is up to 46% of that of Al/SiCp (467MPa), when the infiltration bonding temperature is 670degC. On the study of the infiltration bonding of Al/SiCp/Ti, it is found that there wasn't any interface reactive layer in the joint. Mechanical and metallurgic combinations were all found in the interface at lower temperatures. When the infiltration bonding temperature is 710degC, atoms in the Al/Ti interface occurs interdiffusion and the interface, which has a 10mum thick diffusion layer, was bonded well. About the mechanical properties, it is found that, the bend strength of Al/SiCp/Ti is much more than that of Al/SiCp/FeNi<sub>50</sub> and with the increase of infiltration bonding temperature, the bend strength increased first and then decreased.
The present study focuses on the cooling performance of an environmentally friendly refrigerant HFO-1234yf which serves as a promising working fluid in miniature scale vapor-compression refrigeration system for the thermal management of electronic packaging with high power density. Experimental work was conducted for its flow boiling heat transfer performance in a microchannel with triangular cross section. Flow convection facilitates the effect of boiling in enhancing the heat transfer, particularly in the region with higher the mass flux and lower heat flux. The onset of boiling effect imposed on heat transfer is also being pre-matured by its increasing counterpart from convective flow. The competition between flow convection and boiling takes place leading to either a reduction or a stall in heat transfer performance. A sustenance in high heat transfer coefficient was observed within a certain range of the vapor quality, whereas a speculated “dry out” effect was also found in presence.
An AlCrFeNi quaternary alloy was prepared by design method of high entropy alloy, and microstructure and mechanical properties of this alloy were studied by means of XRD, SEM, TEM and other testing method. The results show that AlCrFeNi alloy has a simple crystal structure (BCC)and phase composition, microstructure is eutectic alloy of NiAl/(α-Fe, Cr) with the nanoscale eutectic spaces. The room temperature compression yield strength, compression strength and compression rates of the AlCrFeNi alloy are 1180MPa, 2162MPa and 40% respectively. Compared with AlCrFeCoNiCu alloy and NiAl alloy, the AlCrFeNi alloy has excellent mechanical properties. The research results can provide a possibility for new shell materials of micro-electronic packaging.
Nano Cu@Ag core-shell powders for electronic packaging were prepared by Liquid phase reduction method. The core-shell powders were characterized by XRD, SEM and TEM. The key problems in the experiment were presented some resolvable solution, and the coating process was optimized. The results showed that the dispersant PVP was added to make the dispersion effect better or the selection of stirring speed could not be too small, which could avoid the agglomeration of coating powder. In view of the incompleteness of powder coating, first of all, the amount of Ag should not be too small, if the amount of Ag was small, the coating was incomplete, then the mixing rate could not be too large, which the integrity of the coated powder would be destroyed. To solve the plethoric product impurities, firstly, PVP concentration could not be too high, otherwise, it would be residual. Secondly, the amount of reactive Ag could not be excessive, and it was as far as possible to ensure that all Ag coated on the surface of Cu powder. The process optimization results showed that the range of PVP concentration was between 5 g/L and 10 g/L, Cu/Ag molar ratio n<sub>Cu</sub>:n<sub>Ag</sub>=7:1, and the stirring speed of the solution was controlled at about 3000 r/min. The Cu@Ag core shell powder prepared had good dispersion and encapsulation effect.
