Hangzhou freqcontrol electronic technology Ltd. Is a leading Chinese manufacturer who involves in piezoelectric crystals, surface acoustic wave filters and the single crystal growth as well as substrates process which for use in the telecommunications and general time and frequency industries.
Rely on our manufacturing facilities and our sister partners we register this organization as cqt (China quartz technology ) for the strategic cooperation, we are able to supply a very broad range of all high precision single quartz blanks with all different possible orientation for tc control; Lithium niobate and lithium tantalate substrates (3", 4" and 6" ) for RF signal picking up in smart mobile and all custom sized special glass substrates for optical windows as well as all commercial-end frequency controlled component at bulk and saw industry for 3G, 4G, and 5g application,
We has been servicing for microelectronic manufacturers, defense related contractors, national laboratories, universities and scientists around the world since 1990. Our expertise is specialty on the single piezo crystal science, all kinds of quartz blank and lithium niobate lithium tantalate wafer manufacture, we are committed to the supply of all types of substrate wafers to the microelectronics industry.
We focus on innovation, cost-effectiveness, and superior quality for our customers. Our accomplishments are the result of the combined efforts of all of our employees, who are dedicated to the highest ethical and quality standards.
From 2007 marked our continued expansion with the addition of ln, lt, qtz substrate products on 3", 4" and also 6" with the most thinner at 0.1-0.15 mm which will make chips to be possible to be packed within more the most of smallest packages.
Up to 2010 years, we developed production capability to all different kind of glass substrates up to 12" to apply for both semiconductor and optical industry.
Expansion into existing markets with leading edge products that exploit today′s advanced manufacturing technologies has become the mainstay of our successful business growth.
CQT's primary goal is "To be a reliable primary microelectronics substrates supplier in today's World". The entire organization, beginning with top management, has worked consistently to meet this goal.
Our reputation for quality is based on a commitment to the newest and most effective design, manufacturing, testing, and management procedures - including, but not limited to, design for manufacturing, statistical process control, lean manufacturing, and continuous improvement methodologies. We have had a fully implemented and effective IATF16949 Quality Management System.
CQT is committed to conduct its all operations in a socially responsible, ethical, and sustainable manner to protect the environment and ensure the safety and health of our employees, customers, and surrounding communities. We are also committed to continuous improvement on all environmental issues. CQT maintains ISO9001/ISO14001 certifications and also implements the EICC standards. and implemented the Electrical Industry Code of Conduct as well.
