Zhang Jianzhou stated that the high input of research and development expenses is a necessary prerequisite for the production of 'core technology'. Nasda is the scarce chip research and development, consumables production, and the whole industrial chain layout of the printer design and manufacturing. The mid- to low-end high-grade production has been put into full production, and the market share has gradually increased. At the same time, in the field of chip design, the company's phase-change memory, FPC chips, and SoC chips have enabled the company to maintain its market competitiveness for a long time.
