Wang Quan Technology (Kunshan) Co., Ltd. established a back-end taping factory in Kunshan in April 2001, and at the same time started to build a factory on Huangpujiang Middle Road. In December 2002, the new factory was completed and began full manufacturing. Wang Quan's products are SMT chip resistors, including chip resistors, array resistors, and network resistors. The current monthly production capacity is 9 billion PCS, which are mainly used in desktop notebook computers, computer peripheral products, network communications, mobile phones, etc. In order to adapt to the trend of miniaturization of electronic products and the requirements of high precision, the company actively develops smaller and more precise products. The company actively completes certifications that meet international standards, and has successively completed ISO9000, ISO14000 and other certifications. As a member of the global village, Wang Quan must also fulfill its environmental protection responsibilities. Therefore, in 2004, it completed the lead-free electroplating terminal electrode and mass-produced RoHS-compliant products in July 2005. Wangquan adheres to the chairman's business philosophy. Maintaining integrity is the principle of persistence, giving back is the unchanging concept, surpassing is the eternal goal, maintaining talent is the driving force of progress, research and development is the rock of development, and continuous efforts are made to make progress. The company has a total investment of US$100 million, covers an area of 119,000 square meters, and now has more than 2,800 employees. In the next 2-3 years, it will realize the corporate vision of becoming the first in the market share of chip resistors in East China.
