Printed circuit boards (PCBs), as the carrier for electrical interconnection of electronic components, are widely used in all aspects of our lives, ranging from consumer electronics such as mobile phones and computers to communications, industrial control, medical,
aerospace and other industries. Precision electronic equipment. It is one of the core basic components of the electronic information industry and an important cornerstone that supports the continuous development of information technologies such as 5G and artificial
intelligence. It is closely related to intelligent and automated modern industrial production.As various industries explore high-quality digital transformation, printed circuit boards are developing in the direction of high density and high precision, and their reliability has increasingly become the focus of enterprises. At the same time, consumer electronic
products are evolving towards smaller and smarter products. In this process, the traditional manual visual inspection method can no longer meet the quality control requirements of high-standard printed circuit boards. As an important automated inspection process,
flying probe testing can complete circuit continuity and insulation testing more accurately and efficiently.
As an equipment company specializing in the R&D and manufacturing of PCB testing equipment, Kunshan Jingmei Electronic Technology Co., Ltd. (hereinafter referred to as "Jingmei Electronics") has numerous high-end equipment and provides end users with high-
quality testing equipment, test OEM, and wire pins. Products and services such as jig making. With the help of Schneider Electric solutions, Jingmei Electronics has developed into a leader in high-end flying probe testers.
Although the flying probe tester has unparalleled advantages in manual visual inspection, there are still some difficulties in technological breakthroughs in its core component servo system, including debugging and response speed, parameter adaptability, precision
positioning control, torque/speed performance, detection time, Overload capacity, etc. Based on its professional technology accumulation in the field of servo motion control, Schneider Electric's new generation Lexium 18 series servo is composed of Lexium 18 servo
driver and BCH18 servo motor. By optimizing the system structure and simplifying the mechanical structure, it can meet the flying probe tester's requirements for accuracy, The demand for stability and agile response has become a reliable tool for Jingmei Electronics to
upgrade its testing equipment and further expand its testing business.
Among them, the Lexium 18 servo driver adopts a highly robust design and uses high test standards to ensure system stability (EMC test standard >= 120% IEC standard). Combined with the online automatic resonance suppression function, the driver can automatically
detect when it is turned on, without cumbersome parameter adjustments, and can be copied and applied to the same model, greatly improving the adaptability of the equipment and realizing "plug and play" for Jingmei Electronics. Effect. In addition, the anti-interference
ability of the system is improved by adding low-frequency filters to the high and low-speed PTI. The Lexium 18 servo driver also supports 16-bit high-precision analog input, which meets the positioning accuracy control requirements of Jingmei Electronics within 50um.
On the other hand, the BCH18 servo motor adopts an advanced motor structure design with spoked permanent magnets embedded in the rotor. By increasing torque density and reducing cogging torque, it shortens its body length by 20%-35% while increasing its overl
oad capacity to 350% and increase the maximum speed from 5000rpm to 6000rpm. By optimizing the T-N curve, especially the torque output capability in the high-speed area, the positioning accuracy and speed of the BCH18 servo motor can reach 4200rpm with the
high-precision control of the Lexium 18 servo driver. Data shows that with the support of Schneider Electric's Lexium 18 series servo, Jingmei Electronics' flying probe test time for ordinary detection boards has been reduced to 76 seconds, reaching higher process standards.
As the core basic component of industrial automation equipment, servo systems are particularly important for their precise positioning capabilities, adaptability, response capabilities, stability and safety performance. Schneider Electric, a global digital transformation expert in
the field of energy management and automation, always adheres to innovation and is committed to providing stable, reliable, convenient and cost-effective digital solutions, empowering enterprises to save overall costs and create more value, and We will work with more partners
to promote the process of industrial automation.
