Shiyu group mainly produces high-precision circuit boards such as mobile phones, automobiles, security and 5g. At present, it has advanced printed circuit board production equipment and manufacturing technology, good production environment and strong production technical force, an excellent technical team and whole process surface treatment equipment, and processes surface treatment processes such as gold deposition and lead-free tin spraying. At present, the company has rented 17000 square meters of workshops, purchased 20 equipment installation production lines, and has an annual output of 2 million square meters of circuit boards. Now, a series of first-class equipment in the industry, such as cosmic horizontal line worth 16 million, Diming electroplating line worth 11 million, and 40 high-precision CNC drilling rigs, are in place. It is expected that 160 high-precision CNC drilling rigs with a total value of 100 million yuan will be deployed after the completion of the project. At present, the company's whole circuit board process and gold deposition process have been put into operation, and all preparations for the crimping process have been completed. After the personnel are in place, it will be officially put into operation in the middle of 2022. The project is expected to produce 2 million square meters of circuit boards in 2023, with an output value of 1 billion yuan.
