basic information

Our company was founded in 1990 with four members. At the time of our establishment, we had no equipment, and each of us primarily worked on renovation projects and manual assembly with just a soldering iron. As the miniaturization of components progressed and the number of prototype and development projects involving BGA increased, the demand for BGA reballing and jumper wiring also grew. Therefore, we decided to introduce BGA rework equipment before implementing basic devices such as reflow ovens. Since then, we have conducted extensive research in technology alongside numerous clients, and we take pride in having established a level of reliability that satisfies our customers, not only for BGA but also for LGA, POP, underfill applications, and 0201 chip mounting. Additionally, our company features a maintained inventory and support for cut parts (My Data), which helps differentiate us from other companies in the same industry. We consider it our mission to address all necessary QCD for development and prototype assembly and provide technical support with customer satisfaction as our top priority. *For more details, please download the PDF or contact us.*
