PCB/Flexible PCB
Our PCB factory is principally engaged in the manufacturing of high density single sided, double sided and multi-layer boards up to 12 layers. Established in 1977 in Hong Kong, our PCB capabilities has grown to a powerful workhorse of over 600 experienced and skilled technicians and engineers. In the fiscal year 1998/99, our annual output reached 3 million square feet and has added boards for a diverse customer base including market leaders in PC systems, computer peripherals, learning aids, telecommunication, power supplies, and instrumentation worldwide. In 1992, we formed our Single-sided Division to serve a variety of needs; specialists in paper phenolic base material keep ourselves active in the demanding market place.
Sophisticated, computer controlled electrical test machines, open-short tests, and high resistance leakage-short tests thoroughly check and confirm each printed circuit board manufactured for our clients retain the highest level of excellence that has earned us our reputation as one of the leading PCB manufacturers in China. Computer Numerical Control (CNC) machines and automated facilities ensure that each process in the technical development of your product proceeds with precision and efficiency. As the electronics world is moving towards high technology, we know the importance of quality and reliability in today’s demanding market place. We are continuously upgrading our facilities, incorporating the latest sophisticated PCB technology to meet future market challenges.
