Guan Bao Technology Co., Ltd., formerly known as Li Chi Precision Electronics Industry Co., Ltd., was established in 1988 to produce resistors and resistors, such as chip-mounted resistors and chip-loaded resistors for module-integrated circuits and ceramic substrates. . In 1998, the company started to develop the SMD diode process. In 1999, it obtained the manufacturing process patent. In June 2002, it began mass production of patch diodes. In April 2003, the trial production of the Schottky diode was implemented. In October, the company produced a diode to provide a truly small, light, and small signal electronic product for the consumer and high-tech era, and to solve the problem of general patch diode thickness. . In order to improve the market demand for technology, quality, and customer diversity, it was deconstructed by Lizhi Electronics Co., Ltd. in November 2003, and was injected with NT$200 million in funds. Guan Bao Technology Co., Ltd. was established, and Mr. Xu Shengxiong continued to serve as a director. Long, Cheng Chengcheng sincerity, transcendence and harmonious enterprise spirit, with innovation, core competitiveness, rapid response, positive intention and execution, in the original patent process and structure of high-quality semiconductor diode products, with strategic alliance partners Fully support the opening of the Innovation Bureau.
