Founded in 1999, Hangzhou Freqcontrol Electronic Technology Ltd. is
a China leading manufacturer of piezoelectric crystal wafers,
substrates, components and single crystal growth. We, known as the
"CQT Group" in global market, headquartered in Hangzhou, China,
empowered by its manufacturing sites in Shanghai, Jiaxing and Deqin
etc.
Our products are mainly used in RF Telecom, Semiconductor, Biotech,
Optical engineering and frequency control industries. The monthly
production capacity: 500K single quartz blanks (SC, AT, IT, FC,
etc.), 20K quartz wafers (AT, ST, X, Z, etc.), 10K LiNbO3 wafers
(3~8 inch), 10K glass wafers (Fused silica, Borofloat33, Corning,
etc.), 8K LiTaO3 wafers (3~6 inch), and 100K filters/oscillators
(VCXO, TCXO).
Our company vision is to be a reliable primary Microelectronic
substrates supplier in today's world.
The CQT Group consists of five major plants with total floor area
over 10,000 m2. Our production machines include crystal growth furnace, wire saw,
X-ray orientation, grinding machine, polishing machine, chamfering
machine, CNC, REDOX chambers etc. Inspection equipment include
Flatmaster 200, AOI, profilometer, optical imager, X-ray inspector
etc. We are also equipped with Class 100 and 1000 clean rooms.
The CQT group is primarily known as the expert of hexagonal
crystals, We master the manufacturing process of single & doubly
rotated quartz blanks, and we can provide quartz of any orientation
cut whether given by IRE , Miller index, Euler angle or
conventional sign.
In addition to our leading quartz blank manufacturing capabilities,
the last decade sees our major technological breakthroughs. We
overcome the 3~6 inch ultra-thin wafer mass production barrier,
obtained the reduction technology of black LiNbO3 & LiTaO3 wafers,
and achieved 8 inch LiNbO3 wafer mass production successfully.
