Foxconn International's departure from mobile phone business is facing a transformation

Foxconn International's departure leaves the mobile phone business in transition On December 2nd, Beijing time, Foxconn International CEO Chen Weiliang announced his departure. Foxconn said that Chen Weiliang will continue to serve as chairman of the company's board of directors. The industry believes that Foxconn's mobile phone business will face transformation.

It is reported that Chen Weiliang had played a major role in the cooperation with Nokia. However, due to sudden changes in the mobile phone market in recent years, new customer cooperation has been hampered, so there is an urgent need to adjust the mobile phone business.

"Foxconn International must transform itself in business before it is possible to get out of the current predicament. This also requires new leaders," said one supplier.

Foxconn stated that Chen Weiliang's departure was due to his desire to focus more on the family side. Since then, he has remained as chairman of the company's board of directors and has participated in the formulation and review of company business plans and strategies. The position of Chief Executive Officer was taken over by Tian Tianxuan, Vice President of Foxconn Technology Group.

Lead Free Piezoelectric Elements


The Co-Al Co-doped Barium Titanate Lead-free Piezoelectric Ceramics was successfully developed by Yuhai company through repeated experiments. By Researching the influence of Co-Al Co-doping on the structure and properties of Barium Titanate-based piezoelectric ceramics, the formulation and preparation technology of Barium Titanate-based piezoelectric ceramics were optimized. Yuhai`s BaTiO3 was prepared by conventional solid-phase sintering method, with the piezoelectric constant d33 (>170pC/N), dielectric loss tgδ≤0.5% and mechanical coupling coefficient Kp≥0.34.

Barium titanate lead-free piezoelectric ceramics are important basic materials for the development of modern science and technology, which was widely used in the manufacture of ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic frequency discriminators, high voltage generators, infrared detectors, surface acoustic wave devices, electro-optic devices, ignition and detonation devices, and piezoelectric gyroscope and so on.

Application: military, ocean, fishery, scientific research, mine detection, daily life and other fields.
