Asymtek's Conformal Coating Technology Adds Reliability to Medical Electronics.Protects Circuitry in Implantable Devices such as Pacemakers Pacemakers Definition A pacemaker is a surgically-implanted electronic device that regulates a slow or erratic heartbeat. Purpose Pacemakers are implanted to regulate irregular contractions of the heart (arrhythmia). CARLSBAD, Calif. -- Asymtek, a Nordson company and leader in dispensing technology and pioneer in jetting technology, improves the reliability of implantable medical devices by supplying equipment to apply conformal coating Conformal coating material is applied to electronic circuitry to act as protection against moisture, dust, chemicals, and temperature extremes that if uncoated (non-protected) could result in a complete failure of the electronic system. materials that protect the electronics inside the devices. Jetting conformal coating materials onto the electronics in life-saving medical devices, such as pacemakers and defibrillators, protects the electronic circuitry from moisture, dust, chemicals, solvents and other types of environmental contaminants. Conformal coating also dampens the effects of mechanical and thermal stresses, vibrations and electrical noise that can impair the functioning of the devices. Asymtek's SC-400 PreciseCoat[TM] Conformal Coating Jet enables the application of coating materials to highly selective areas, especially on small substrates, devices or substrates with high-component density where there are tight tolerances between coated and uncoated areas. Delivery of the coating is so accurately controlled that only the part of the device that needs coating is protected, without the need to mask any surrounding areas. It is a clean process, which is especially important in the manufacture of sensitive implantable medical devices. "When assembling something as critical as a pacemaker pacemaker Source of rhythmic electrical impulses that trigger heart contractions. In the heart's electrical system, impulses generated at a natural pacemaker are conducted to the atria and ventricles. , medical device manufacturers do the utmost to make their products reliable," said Jim Klocke, senior business development manager of Asymtek. "Applying conformal coating to the electronics in these devices provides extra assurance that they will be reliable and perform as designed."

About Asymtek Asymtek([R]), a world leader in automated fluid dispensing and pioneer of jetting technology, designs and manufactures a full line of dispensing and conformal coating systems for semiconductor package and printed circuit board assembly as well as automotive, medical, aerospace, disk drive, flat panel display A thin display screen for computer and TV usage. The first flat panels appeared on laptop computers in the mid-1980s, and the LCD technology became the standard. Stand-alone LCD screens became available for desktop computers in the mid-1990s and exceeded sales of CRTs for the first time , optoelectronic, appliance and other precision industrial manufacturing applications. Asymtek products deliver a wide variety of fluids, including glues, epoxies This article is about the band named the Epoxies. For the adhesive, see Epoxy. The Epoxies are an American band from Portland, Oregon formed in 2000. Heavily influenced by punk rock and New Wave the band has described themselves as robot garage rock. , solder pastes, coatings and gasketing materials. Founded in 1983 and acquired as a subsidiary of Nordson Corporation (Nasdaq:NDSN NDSN National Drug Strategy Network ) in August 1996, Asymtek is an ISO (1) See ISO speed. (2) (International Organization for Standardization, Geneva, Switzerland, www.iso.ch) An organization that sets international standards, founded in 1946. The U.S. member body is ANSI. 9001:2000 certified company. Asymtek has received numerous awards, including Intel's prestigious Supplier Continuous Quality Improvement award for three years in a row: 2003, 2004 and 2005.
