Overview
Behavior Tech Computer, commonly known as BTC and formally identified as Behavior Tech Computer Corporation, is a Taiwanese technology manufacturing company headquartered in New Taipei. Established in 1982 in Xizhi by Ke-Kang Su, the company initially concentrated on keyboards for IBM PC-compatible computers, while also producing power-supply units and computer cases. Its early keyboard business was notable because BTC developed and manufactured its own switches rather than depending entirely on outside suppliers. The company began with capacitive keyboard designs using foam-and-foil switch elements and later introduced mechanical keyboards based on a design licensed from a Japanese company. BTC expanded rapidly during the 1980s and 1990s. By 1986, it was producing approximately 25,000 keyboards per month and had reported sales of about US$5 million. That year it established an American subsidiary in Fremont, California. By 1993, BTC had become Taiwan's largest keyboard manufacturer and was described as the world's third-largest keyboard producer. Its international presence continued to grow through branch offices in London, Germany, France, and the Netherlands. European sales represented a significant portion of the company's revenue during the early 1990s, reflecting BTC's development as an export-oriented manufacturer. The company broadened its activities beyond keyboards as computer-peripheral markets matured. Its portfolio came to include mice, sound cards, graphics cards, scanners, webcams, GPS receivers, complete computer systems, and other hardware. In 1993, BTC formed a joint venture with Oak Technology to manufacture graphics cards using Oak accelerator chips. It also entered optical storage, producing CD-ROM drives and later video CD players, as well as ergonomic keyboards. BTC constructed or operated manufacturing capacity for optical drives in Taiwan and established a multilingual-keyboard plant in France. Its CD-ROM production reached approximately 30,000 drives per month when the products entered the market in 1995. BTC also participated in broader industry initiatives. In 1997 it joined a hardware-manufacturer alliance led by Rockwell Semiconductor to promote the K56Flex modem-transmission standard. At the same time, declining margins in conventional keyboard manufacturing encouraged a shift toward optoelectronics and multimedia products. By 2003, optoelectronic products accounted for a larger share of sales than traditional input devices, while exports represented roughly 90 percent of total sales. The company operated through a combination of original-equipment manufacturing, original-design manufacturing, and distribution of BTC-branded products in Asian, North American, and European markets. During the early 2000s, BTC maintained a substantial international operating network. Its activities included offices, factories, distribution facilities, and warehouses across Taiwan, mainland China, Europe, North America, and other Asian markets. The company continued to invest in research and development, quality assurance, and high-volume keyboard production, even as it diversified into optical and multimedia hardware. Its production footprint included facilities or operations associated with Taiwan, France, South Korea, Hungary, the Czech Republic, Dongguan, and other locations. The optical-disc business subsequently came under pressure from intense competition, patent-related issues, changing market economics, and the effects of the global financial crisis. In 2005 BTC began transferring optical-drive production to Foxconn as a contract manufacturer. In 2006 it closed laser-assembly lines, stopped selling its own optical-drive brand internationally, and retained only more limited drive-related activities in selected markets. In 2008 it exited the optical-disc-drive business altogether. By the mid-2010s, BTC had pivoted toward industrial LED production. The available reference material does not establish the company's current operating status, present product range, website, or executive leadership.
History
Behavior Tech Computer was founded in 1982 in Xizhi, New Taipei, by Ke-Kang Su. Its initial business focused on keyboards for IBM PC-compatible computers, supplemented by power-supply units and computer cases. Early BTC keyboards used capacitive switching based on foam-and-foil elements. Unlike many Taiwanese competitors, BTC developed its own switches, giving it greater control over product design and manufacturing. The company expanded during the 1980s. In 1986, it was producing about 25,000 keyboards per month, had sales of approximately US$5 million, opened a subsidiary in Fremont, California, and began Taiwanese production of mechanical keyboards using a Japanese-licensed switch design. By 1993, BTC was Taiwan's largest keyboard manufacturer and ranked third globally. It developed a growing European presence, with offices in London, Germany, France, and the Netherlands. European markets accounted for about one-quarter of revenue in 1993. BTC became publicly listed on the Taiwan Stock Exchange in 1995. During the 1990s, BTC diversified into a broad range of computer hardware. Products included mice, sound cards, graphics cards, scanners, webcams, GPS receivers, complete computer systems, ergonomic keyboards, and optical-disc equipment. In November 1993, it created a joint venture with Oak Technology to manufacture graphics cards using Oak accelerator chips. BTC entered the optical-storage market with CD-ROM drives and later video CD players. It also established optical-drive production capacity in Taiwan and a multilingual-keyboard operation in France. By the spring of 1995, its CD-ROM output was approximately 30,000 units per month. As keyboard prices and profit margins declined, the company moved toward optoelectronics and multimedia hardware. Webcams, optical drives, and GPS products became increasingly important. By 2003, optoelectronics accounted for 42 percent of sales, compared with 17 percent for traditional input devices. Exports represented about 90 percent of sales. BTC combined OEM and ODM contracts with sales of its own branded products in Asia, North America, and Europe. Its international infrastructure included offices and manufacturing or distribution operations in Taiwan, mainland China, Europe, South Korea, and the United States. The company maintained substantial manufacturing and engineering capacity in the early 2000s. In 2004 it employed more than 710 people worldwide, including hardware engineers, software developers, and quality-assurance staff. A large keyboard plant established during this period was designed for monthly output of roughly 1.5 million to 2.5 million keyboards. Its broader network included facilities or activities in Taiwan, France, South Korea, Hungary, the Czech Republic, Dongguan, and other locations, supported by warehouses and distribution hubs in several countries. Optical drives eventually became difficult to sustain amid intense competition, intellectual-property concerns, and weakening market conditions. In 2005 BTC began outsourcing optical-drive production to Foxconn. In 2006 it closed laser-assembly lines and stopped selling its own branded optical drives internationally, while continuing limited sales in China and Taiwan. In 2008 it exited the optical-drive sector entirely. The available account attributes the decision to patent conflicts and the impact of the Great Recession on Taiwan's economy. By the mid-2010s, BTC had pivoted toward industrial LED production. This marked a significant change from its historical identity as a major keyboard and computer-peripheral manufacturer. The supplied reference material does not provide reliable current information about its corporate status, present leadership, product catalogue, or official website.
