Johnson Matthey Electronics Introduces a New Fast Cure Die Attach Adhesive for Plastic Molded Leadframe Packages.SINGAPORE--(BUSINESS WIRE)--May 5, 1998 -- JM825 Dramatically Improves Production Cycle Times by More Than 80 Percent And Enhances Product Reliability Without Capital Investment To address customers' needs for higher reliability and yields, Johnson Matthey Johnson Matthey plc (LSE: JMAT) is a British chemical company which has its headquarters near Holborn in central London. It is traded on the London Stock Exchange and is a constituent of the FTSE 100 Index. Electronics (JME JME Journal of Medical Ethics JME Juvenile Myoclonic Epilepsy JME Jones Matrix Eigenanalysis (method to measure polarization mode dispersion, ITU-T) JME Java Management Environment JME Java Management Extensions ), a global supplier of high-technology materials to the microelectronics industry, has developed a new, fast curing die attach paste for plastic molded leadframe packages. The product was introduced here today at the SEMICON SEMICON Semiconductors Equipment and Material International Conference Singapore Test, Assembly & Packaging show. Called the JM825, the new paste is intended for high-volume, high-capacity leadframe applications, including quad flat packages (QFPs), plastic leadless chip carriers (PLCC (Plastic Leaded Chip Carrier) A plastic, square, surface mount chip package that contains leads on all four sides. The leads (pins) extend down and back under and into tiny indentations in the housing. See chip package. ), small outline integrated circuits Integrated circuits Miniature electronic circuits produced within and upon a single semiconductor crystal, usually silicon. Integrated circuits range in complexity from simple logic circuits and amplifiers, about 1/20 in. (1. (SOICs) and plastic dual in-line packages (PDIPs). JM825 improves upon industry standard epoxy pastes, which are used by more than 80 percent of the die attach adhesive market, with proprietary technologies and improved chemical properties that drastically increase paste and package reliability without further capital investment. JM825 will be manufactured at JME sites in San Diego and Singapore. Historically, the snap-cure die attach process has been difficult to implement due to the high equipment costs, inconsistent thermal exposure, potential voiding at cure, and high thermally induced stress for larger die size applications. The JM825 incorporates a proprietary, high-functionality epoxy resin matrix that maintains existing technology protocols, but features excellent cure times of less than 10 minutes in conventional box ovens, thereby improving productivity and capacities without the need for additional investments. "This new die attach product gives semiconductor companies a new choice to reduce their packaging costs and make better chip packages," said Bernard Ho, marketing manager for die attach products. "Not only have we reduced the amount of time the epoxy takes to cure, thereby reducing thermal budgets, we have also cut the moisture absorption rate of the paste, increasing its reliability and performance and therefore that of the finished product, the IC." Other product features include high electrical conductivity, low resin bleed and low outgassing Outgassing (sometimes called "Offgassing," particularly when in reference to indoor air quality) is the slow release of a gas that was trapped, frozen, absorbed or adsorbed in some material. characteristics, which lead to higher JEDEC The division of the Electronic Industries Alliance (EIA) that deals with semiconductor standards (officially, the JEDEC Solid State Technology Association of EIA). JEDEC was formed in 1958 when the Joint Electron Tube Engineering Council (JETEC) split into two Joint Electron Device classifications. Johnson Matthey Electronics is a world-leading supplier of high-technology materials to the semiconductor and microelectronics industries, with 24 manufacturing locations worldwide generating annual sales of more than $650 million.
