factory/facilities

Ideally located in Southern China, our PCB factory is a 4-stories building with a total floor space of 21,000 square-meters. Within the same campus, there is also a separate 4,000 square-meters Tooling factory providing tight integration and rapid response to support our customers' requirements. We have instituted a straight quality policy and our facility is currently ISO-9001:2000, QS-9000:1998 certified. To further enhance our Quality and Green (Q&G) initiatives, our target is to complete certifications for ISO-14001 and ISO/TS-16949 in 2005. A member of Hong Kong Printed Circuit Association (HKPCA), we have been actively engaged in various industrial tradeshows and associations.

In 2003, we have expanded our products to flexible PCB. Our single-sided flexible circuits for optical drives have been well accepted and recognized for its extraordinary reliability under extended flexural bending tests. Now, we have the ability of manufacturing multi-layer Flexible Circuits for various consumer electronics such as cellular phones. Our current manufacturing capacity is 40,000 square-meters per month for rigid boards and 25,000 square-meters per month for flexible circuits.
