Drilling, exposure, forming and testing are the key processes in PCB manufacturing. The performance, function and reliability of relevant equipment will directly affect the processing quality of PCB. With the rapid development of 5g communication, automotive electronics, consumer electronics and other industries, the market demand for medium and high-end PCB boards is increasing day by day. Due to its more complex structure and greater processing difficulty, it puts forward higher requirements for the technical level of PCB special equipment.
Through independent research and development and innovation, the issuer has built the core technology covering the four key processes of PCB, as follows:
Serial number core technology name mainly applies product technology protection means
1. Patents and software copyrights of main products of motion control technology of high acceleration and deceleration direct drive motor
2 precision mechanical design and advanced assembly technology, main product patents and proprietary technology
3. Patents and software copyrights of main products of CAE optical electromechanical joint digital virtual simulation technology
4 special software platform and core algorithm technology software copyright and proprietary technology of main products

6. Micro blind hole drilling technology, laser drilling equipment patent and software copyright
7. High precision lightweight workbench manufacturing technology, mechanical drilling equipment, mechanical forming equipment patents and proprietary technology
8. Patents and software copyrights of multi scene precision electrical performance testing technology and testing equipment
The advanced technology of the issuer's core technology is as follows:
1. Motion control technology of high acceleration and deceleration direct drive motor
Most of the motion modes of PCB special equipment are short-distance, fast start and stop, high acceleration and deceleration, fast and stable point motion, while the linear motor driving technology is generally used in the occasions of ultra-long stroke and ultra-high running speed. Therefore, most of the early PCB special equipment used the driving mode of rotating motor and rolling bead wire rod, although it can achieve large thrust and acceleration, However, it will adversely affect the accuracy and service life of the product. After years of research and development, the issuer has repeatedly summarized that using the characteristics of no intermediate mechanical transmission link in the linear motor drive technology, the system response time is greatly shortened (electromagnetic conversion time is the mechanical response time). Combined with the issuer's self-made lightweight sports body, the issuer has earlier adopted the linear drive technology in its Chinese counterparts, and designed and customized high peak thrust, high response The special linear motor with low electrical time constant and low heat consumption is used in the transmission system of various types of special equipment of the issuer, which greatly improves the performance. Especially for the application of the moving shaft of PCB mechanical drilling machine, the electromechanical matching of the issuer's mechanical drilling machine is greatly improved, and the acceleration and deceleration and response speed of the drilling machine are greatly improved. The XY axis motion acceleration of PCB mechanical drilling equipment using this technology can reach 1.5 times of gravity acceleration, and the Z axis acceleration can reach 5 times of gravity acceleration. Compared with the equipment using ball screw transmission technology, the drilling efficiency is increased by about 15%, and the drilling accuracy is also significantly improved.
2. Precision mechanical design and advanced assembly technology
PCB special equipment covers multiple modules such as mechanical system, optical system, control system and software system, involving hundreds of devices such as spindle, servo motor, workbench and hood. However, the PCB production process has high requirements for machining accuracy, and the allowable error is generally in micron or even submicron level, The issuer needs to have extremely precise mechanical design ability and assembly ability. In terms of mechanical design, the issuer's R & D personnel have many years of experience in precision mechanical design of PCB special equipment. Through the analysis of the stress and deformation of each part, they can identify the weak links in the mechanical structure, optimize its topology by means of material selection and structural design, and select or select the precision parts that can meet the needs of customers, Lay the foundation for the precision of the whole machine. In terms of assembly technology, the issuer cooperated with special tooling and fixtures to create a unique assembly process method, and reasonably allocated and optimized the total tolerance between different assembly processes and parts, so as to continuously improve and break through the processing accuracy of the issuer's products.
3. CAE optical electromechanical joint digital virtual simulation technology
Under the traditional R & D process, the R & D personnel first design the prototype drawings, and the production and assembly personnel trial produce the physical prototype according to the prototype drawings. According to the test results of product function and performance, the scheme is continuously modified and optimized, and the prototype production and test are repeated until the product meets the design requirements. With the continuous improvement of the technical level of PCB special equipment, the difficulty of R & D continues to increase. The problems of high R & D cost and long R & D cycle caused by the traditional R & D process are becoming increasingly prominent, which is difficult to meet the highly iterative product needs of downstream customers.
The issuer is one of the first enterprises in the industry to apply CAE digital virtual simulation technology to product design. The R & D team of the issuer combines the professional knowledge of mechanical design, electrical engineering, electronic technology, optoelectronics and laser technology, automatic control technology, computer software and other disciplines with many years of practical R & D experience, and endows simulation parameter conditions in digital modeling, so as to construct a complete virtual digital prototype, The digital prototype simulation is used to simulate the actual working situation, and the digital test and verification of the main parameter performance is carried out to provide guidance for the scheme optimization, so as to ensure the success of the physical prototype at one time, save the time of repeated physical verification, avoid the waste of prototype materials, and greatly improve the R & D efficiency.
4. Special software platform and core algorithm technology
Due to the gradual complexity of the software system and the professionalism and diversity of the software development of PCB special equipment, the software developers of the issuer, with many years of experience in the development of PCB special equipment, summarized cases and application scenarios, made a forward-looking prediction of the future technology, established special software development system tools, adopted platform design and reserved multiple ports. At the same time, the issuer modularizes the used function development software package, which is convenient for product iterative combination and upgrading, and continuously expands the unique algorithms such as packaging path optimization, laser energy control, dynamic following and so on. For the document analysis of proprietary processing programs in PCB special equipment industry, the issuer has also formed a unique analysis method, which can quickly and accurately convert them into machine executable documents. On the software platform, the issuer has also established an agile software system development process to fully combine software development with business requirements and guide the continuous innovation and development of software technology. The issuer uses the "funnel" mode to sort, classify and sort thousands of information through the process, and finally form the task objectives of each role's daily work, so as to ensure the efficient and high-quality progress of software development.
