Abstract: Disclosed are rapid and reproducible methods for separating and purifying nucleic acids from paraffin-containing tissue samples. The disclosed methods involve a melting step, where paraffin-containing tissue samples are heated in the presence of a detergent, causing the paraffin to melt and tissue sample cells to lyse. From the resulting two-phase mixture (i.e., a paraffin phase and an aqueous phase), the aqueous phase is collected for purification of nucleic acid. Protease(s) can be used at one or more points in the separation process to facilitate tissue cell lysis and/or degrade proteins that could degrade nucleic acid or interfere with subsequent genetic manipulation or analysis.

Abstract: High yield, high reliability, flip-chip integrated circuit (IC) packages are achieved utilizing a combination of heat and pressure to bond flip-chip die and to cure no-flow underfill material. The underfill comprises a filler or low coefficient of thermal expansion (CTE) material to decrease CTE of the cured underfill. The filler material can be selected from the group comprising silica, silicon oxide, silicon dioxide, silicon nitride, aluminum oxide, aluminum nitride, or a mixture thereof. The filler material may also increase the viscosity of the uncured underfill and/or increase the modulus of elasticity of the cured underfill. In some method embodiments, a thermocompression bonder is used to simultaneously provide solder bump reflow and underfill curing. Application of various methods to a component package, an electronic assembly, and an electronic system are also described.
