Development History

Yantai Crystal Technology Electronics Co., Ltd. was brought into being with a total investment of 15 million CNY, and it was engaged in the production of HC-49U quartz crystal at first.

Yantai Crystal Technology Electronics started to make HC-49S quartz crystal.

Yantai Crystal Technology Electronics released HC-49S SMD quartz crystal to the market.

Shenzhen Crystal Technology Electronics Co., Ltd. was established.

Shenzhen Crystal Technology Electronics passed ISO 9001:2000 certification, while quartz crystal filter and tuning fork crystal were put into batch production in Yantai.

A branch office was set up in Suzhou City, Jiangsu Province, China.

Crystal Technology Electronics (HK) Co., Ltd. was founded. Then, our seam sealed SMD crystals were produced, and their sizes are 8×4.5mm, 7×5mm and 6×3.5mm.

Shenzhen Crystal Technology Industrial Co., Ltd. was officially inaugurated, and it was focused on diversified business. Then, 5032 SMD crystal was constructed, and our products were confirmed to be Pb-free by SGS.

SJK was honored as the BEST SUPPLIER by TXC Corporation, and 5032 crystal oscillator was successfully developed.

3225 quartz crystal and 3225 crystal oscillator were fabricated, and we built up a SMD production line (30% share) in Anhui Province, China.

Our company passed ISO 14001:2004 certification, and we were recognized as the Green Partner of Sony as well as Excellent E-Business Enterprise. Additionally, Kingdee K/3 ERP system was introduced.

We became an official agency of TXC to sell TXC’s TCXOs and VCTCXOs. In this year, our products passed RoHS certification, and the small sized 3225 SMD crystal oscillators were released to the market to work with M/P, GPS and bluetooth. Moreover, new but strong shareholders were introduced to broaden product catalog, and we were authorized by ZhongJingWei Micro-Electronic Technology Development Co., Ltd. to sell their IC products.

We passed DNV (ISO080000) certification, and our 3225 SMD crystal obtained relevant intellectual right. On the other hand, our company was named as a High-Tech Enterprise.

We were authorized to sell keyboard encoder IC and mouse IC of ELAN Microelectronics Corporation as well as touch screen IC supplied by ZILLTEK Technology Corporation.

Our company was awarded as 2010 China Top 10 Potential Enterprise of Electronic Component, while our 2520 SMD crystal and 2016 SMD crystal were successfully developed. In addition, we offered a 2.4G solution for keyboard and wireless mouse.

SJK was named as 2011 China Top 10 Famous Brand of Electronic Component, and our general manager, Sun Gang, was selected as 2011 China Top 10 Outstanding Talent of Electronic Component. At the same time, we became a member unit of Shenzhen Entrepreneur Association, and we were allowed to sell YOBON power-supply IC and MOS-based power supply.

SMD quartz crystal with an ultra small size (1.6×1.2mm) was put into production.
