Abstract: A method for utilizing one or more pre-formed underfill compositions in the application of surface mount components, most commonly chip scale packages (CSP's), to substrates for use in electronic devices. The pre-formed underfill of the invention is applied directly to the top and/or sides of the CSP before the reflow process and softens during reflow to flow across the circuit/board gap. One underfill composition utilized for this method comprises a thermoplastic film system that provides a coating on the component that is smooth and non-tacky. The film may be applied selectively to parts of the CSP such that it overhangs the top of the component and upon reflow flows over the edge of the CSP to form a connection with the substrate. A second pre-applied underfill composition or solder paste may be applied as an adhesive to provide sufficient tack in order to hold the electronic assembly together during the assembly process and to serve as a flux to facilitate solder wetting.

Abstract: A novel method of producing maize grain with desirable functionality has been developed involving planting two different maize hybrids within the same field. The two maize hybrids are planted in alternating blocks of rows. One hybrid is male sterile such that the second hybrid provides pollen for the entire field. This leads to blocks of two separate types of grain which may be harvested and processed separately.

Abstract: The present invention is directed to a cationic polymer emulsion binder that may be combined with a cationic active ingredient and used as a non-woven binder. This combination of cationic binder and cationic active ingredient may occur as a mixture of a cationic binder and at least one cationic active ingredient, which is then applied to loose fibers to form a non-woven; or the combination may occur after a non-woven is formed using a cationic binder, and said non-woven is then contacted with a cationic active ingredient. Non-woven wipes of the invention retain far less cationic active ingredients during use, resulting in less waste and less use of the active ingredients for the same effect as wipes made with anionic or non-ionic binders.

Abstract: These compounds contain an oxetane functionality and a styrenic functionality. The oxetane functionality is homopolymerizable in reactions that undergo cationic or anionic ring opening, and the styrenic is polymerizable with compounds such as electron acceptor compounds. The dual functionality allows for dual cure processing. The compounds will have the structure in which R1 is a methyl or ethyl group; R2 and R3 are H or a methyl or ethyl group; R4 is a direct bond or a divalent hydrocarbon; X and Y are independently a direct bond or an ether, ester, amide, or carbamate group, provided both X and Y are not a direct bond; Q is a divalent hydrocarbon (which may contain heteroatoms of N, O, or S); and G is —OR1, —SR1, or —N(R2)(R3), in which R1, R2 and R3 are as described above.

Abstract: These compounds contain an oxetane functionality and a cinnamyl functionality. The oxetane functionality is homopolymerizable in reactions that can undergo cationic or anionic ring opening, and the cinnamyl functionality is polymerizable with compounds such as electron acceptor compounds. The dual functionality allows for dual cure processing. The generic structure of such compounds is in which R is a methyl or ethyl group, X and Y independently are a direct bond, or an ether, ester, or carbamate group, and Q is a divalent hydrocarbon (which may contain heteroatoms of N, O, or S), provided that X and Y will not both be direct bonds in the same molecule.
