The company’s equipment is used in numerous industries, chief among which are aerospace, automotive, batteries, electronic components, general electronics assembly, and medical devices. Miyachi America Corporation has 185 employees, with 11 sales and manufacturing offices serving about 11,000 customers worldwide. More than 80,000 items are manufactured annually. The company is certified to ISO 9001, China Compulsory Certificate (CCC), European Conformity (CE), and Canadian Standards Association (CSA) quality certifications. ==Company History== Amada Miyachi America Corporation, an Amada Group company, was founded as the Weldmatic Division of Unitek Corporation in 1948. Unitek Corporation was founded with the introduction of the first stainless steel orthodontic bracket, manufactured by a group of orthodontists in Pasadena, CA. The name “Unitek” comes from the term “Universal Bracket Technique.” Early welding equipment designed and manufactured by Unitek Corporation included the stored energy resistance welding systems (CD/capacitive discharge), initially developed to weld the brackets on the orthodontic bands used to straighten teeth. This equipment almost immediately found application in the electronic industry, eventually replacing AC/direct energy systems used to manufacture guns for cathode ray tubes. It produced significantly better welds and production yields. Weldable strain gages and many diverse electronics assembly applications quickly followed. Early product lines focused on operator-run semiconductor machines for wire bonding and chip attachment, as well as reflow bonding systems, thermodes, and weld monitors. Although the company did not invent the first resistance welders, it perfected the technology and was the first to apply it to welding small microelectronic modules. Early innovations developed during the 1950s through the 1980s include: * Weldmatic Model 32 Weld Head and its successors used a patented force firing system that was critical in small part welding. Direct mechanical digital readout of firing force evolved and was followed by electronic strain gage force monitoring and profile control systems. * Development of SCR discharge circuitry to replace mechanical relay firing systems (contactors) for the semiconductor industry. * Unibond® pulsed bonding power supply, with patented Voltage + Current feedback control. * Unitip® electrodes for fine wire bonding. * Electro-magnetic weld head system consisting of linear force actuator and microprocessor process control. * Weld Sentry® weld monitors and process control systems. * Unipulse® welding transformers designed for half-cycle, uni-polar operation at speeds up to 5 welds per second. * Micropull electronic controlled wire bond tensile non-destruct and destruct pull testers. * Computer interfaces for wire bond pull testers to provide automated data collection as well as closed loop process control systems to detect operator and/ or machine errors. The company was acquired by Bristol-Meyers in 1978, and again by Minnesota Mining and Manufacturing Company (3M), in 1987. 3M subsequently divested the equipment division from its dental products division in 1988, after which it became an independent company. The company was reorganized as Miyachi Unitek Corporation on September 30, 1994, when Miyachi Corporation purchased it and merged it with the former Miyachi America Company. In October 2013, Miyachi Unitek changed its name to Miyachi America Corporation. The name change aligns Miyachi Unitek with other Miyachi Corporation companies around the globe. The company will continue to use the Miyachi Unitek brand name, taking advantage of its brand recognition in the marketplace. Amada Miyachi America's products are used worldwide in the assembly of precision microelectronic parts, devices, and products in a wide range of industrial applications. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Amada Miyachi America」の詳細全文を読む スポンサード リンク
