Thermal Analysis of Novel Underfill Materials with Optimum Processing Characteristics

چکیده
This work encompasses the development of low-viscosity cyclic oligomer underfill formulations that cure without heat evolution. Boron nitride, silica-coated aluminum nitride, and alumina ceramic powders were used as fillers in cyclic butylene terephthalate oligomer melts. The melts were heated with a suitable catalyst to induce polymerization. The effects of the filler type and composition on the thermal and mechanical properties of the poly(butylene terephthalate)/filler composites were examined with differential scanning calorimetry, temperature-modulated differential scanning calorimetry, thermogravimetric analysis, thermomechanical analysis, and dynamic mechanical analysis. Scanning electron microscopy was employed to elucidate the morphology of these composites. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 98: 1300–1307, 2005

متن کاملDouble-Layer No-Flow Underfill Materials and Process
The no-flow underfill has been invented and practiced in the industry for a few years. However, due to the interfering of silica fillers with solder joint formation, most no-flow underfills are not filled with silica fillers and hence have a high coefficient of thermal expansion (CTE), which is undesirable for high reliability. In a novel invention, a double-layer no-flow underfill is implement...

Ten different underfill materials with different size and content of filler and epoxy are studied in this paper. Their curing conditions such as time and temperature are measured by a differential scanning calorimeter (DSC) unit. Their material properties, such as the CTE (coefficient thermal of expansion), T g (glass transition temperature), dynamic storage modulus, tangent delta, and moisture...
متن کاملScanning Acoustic Microscopy Investigation of Engineered Flip-chip Delamination
The rapid uptake of flip-chip technology within the electronics industry, is placing the reliability of such assemblies under increasing scrutiny. A key feature of the assembly process is the application of underfill to reinforce the attachment of the die to the printed circuit board. This has been identified in numerous studies as one of the major ways in which the reliability of the devices c...
متن کاملUnderflow Process for Direct-Chip-Attachment Packaging
-In flip-chip packaging an underfill mixture is placed into the chip-to-substrate standoff created by the array of solder bumps, using a capillary flow process. The underfill mixture is densely filled with solid silica particles to achieve the desired effective coefficient of thermal expansion. Thus during the flow process the underfill mixture is a dense suspension of solid particles in a liqu...
