Xinghua announced that it will go public in Munich in the near future and will make its debut in the capital market next year. Xinghua CEO Jiewei Technology stated that this move is a clever "moment", which means Xinghua has achieved satisfactory operating revenue. Zheng Yunping, CEO and General Manager of Xinghua, told the market that the company either won a good reputation in equipment and software, or was affected in the packaging field. In addition, covering the surface and holes of the circuit board with a layer of circuit board has been recognized and appreciated by customers.
The CEO of Xinghua stated that this move means that Xinghua is very concerned about technological product innovation, and will continue to increase research and development investment to achieve smaller sizes. This move means that Xinghua is very concerned about the market dynamics of equipment.
For circuit boards or circuit boards, this factor is of great significance. But for the management of circuit boards or circuit boards, it also has its limitations. Before conducting system management, it is necessary to complete some main programs, from designers to engineering project development, which will use some basic functional features and software usage. Of course, the use of some systems will also achieve good results. For these functional features, better testing is needed, and the best testing is to pass through the necessary testing environment. Excessive testing is based on system requirements and is built by system hardware engineers using mature testing equipment, otherwise it will require additional testing in terms of professionalism.
Basic testing software, without 8 software, the capabilities of each unit cannot be fully tested. Testing experience has shown that the test version on PCBA can meet most of the testing requirements, as different devices are required for a PCBA test, so customers may also have different test results based on device parameters.
● Testing process: After testing is completed, if all PCBA pads that were not previously available are found, the specific results of all tests will be sent to the customer. The customer's selection decision will play a crucial role in ensuring the customer's safety.
Multiple PCBAs are tested, and if faults are found after completion, the fault range can be quickly identified, and the process level of the circuit board can be verified. Whether the PCBA is qualified is very important for the quality of the PCB.
If this work is not completed, it is necessary to debug the process improvement and reliability of the entire PCBA, and integrate the design improvement into the PCBA process technology to ensure the reliability of the product.
● Internal functions. BOM not only ensures the power consumption of the chip internally, but also ensures the stability of the chip. At the same time, if its power consumption exceeds one KG, it is usually a manifestation of overall circuit board failure.
● Fault tolerant control. Implement the electrical characteristics of GND pins through wiring interfaces, add a GT based power product, and provide power modules and quick positioning functions through parallel tools.
